MCP ServerFree

🔥 Official Firecrawl MCP Server - Adds powerful web scraping and search to Cursor, Claude and any other LLM clients.

Open Source

/ 100

12 capabilities

Capabilities12 decomposed

single-page web content scraping with format selection

Medium confidence

Scrapes individual web pages using the Firecrawl SDK's scrapeUrl() method, returning content in either markdown or HTML format. The MCP server wraps the @mendable/firecrawl-js v4.9.3 client with Zod schema validation for parameters, automatically handling retries via exponential backoff (configurable 1-10s delays with 2x multiplier) and rate-limit errors across up to 3 attempts. Clients specify URL and desired output format through standardized MCP tool parameters.

Solves for

I need to extract readable text content from a single webpage to feed into an LLMI want to scrape a page and preserve HTML structure for downstream processingI need to reliably fetch web content with automatic retry on transient failures

Best for

LLM agents in Cursor/Claude Desktop needing real-time web context

developers building content extraction pipelines with fallback handling

teams prototyping web-aware AI applications without managing HTTP clients

Requires

FIRECRAWL_API_KEY environment variable (for cloud) or FIRECRAWL_API_URL (for self-hosted)

Node.js 18+ (FastMCP runtime requirement)

MCP client supporting stdio, SSE, or HTTP transport

Limitations

Single URL per request — no batching at the scrape level (use firecrawl_batch_scrape for multiple URLs)

Markdown output may lose semantic HTML structure for complex layouts

Rate limiting enforced by Firecrawl API — 3 retries max before failure

What makes it unique

Exposes Firecrawl's scrapeUrl() through MCP protocol with automatic exponential backoff retry logic (configurable via FIRECRAWL_RETRY_* env vars) and Zod-validated parameter schemas, enabling LLM clients to invoke web scraping without managing HTTP or retry complexity

vs alternatives

Simpler than building custom HTTP+retry logic and more reliable than raw Firecrawl SDK calls because MCP standardizes the interface and FastMCP handles transport negotiation across Cursor, Claude Desktop, and other clients automatically

batch url scraping with asynchronous job tracking

Medium confidence

Submits multiple URLs for scraping in a single API call via batchScrapeUrls(), returning a batch_id immediately for asynchronous processing. The server stores no state itself — clients must poll firecrawl_check_batch_status with the returned batch_id to retrieve results as they complete. Internally uses the @mendable/firecrawl-js SDK with exponential backoff retry on submission failures, but does not block waiting for batch completion.

Solves for

I need to scrape 50+ URLs efficiently without making individual API callsI want to submit a batch job and check status later without blocking my agentI need to extract content from multiple pages and process results asynchronously

Best for

agents processing large URL lists (10-1000+ pages)

workflows where scraping latency is acceptable and async polling is feasible

teams with credit budgets wanting to batch API calls for efficiency

Requires

FIRECRAWL_API_KEY environment variable (cloud) or FIRECRAWL_API_URL (self-hosted)

Array of valid URLs (minimum 2, practical maximum depends on Firecrawl plan)

Client-side polling mechanism to check batch status periodically

Limitations

Asynchronous only — returns immediately with batch_id, requires separate status-check calls

No built-in polling loop — client must implement retry logic for status checks

Batch job lifetime limited by Firecrawl API (typically 24-48 hours)

What makes it unique

Implements fire-and-forget batch submission pattern via MCP, returning batch_id immediately without blocking, paired with separate firecrawl_check_batch_status tool for polling — enables agents to submit large jobs and continue reasoning while scraping happens server-side

vs alternatives

More efficient than sequential single-page scraping for 10+ URLs because Firecrawl batches them server-side; more flexible than synchronous batch APIs because clients control polling frequency and can interleave other work

environment-based configuration with cloud/self-hosted api switching

Medium confidence

Configures the entire server via environment variables, enabling seamless switching between Firecrawl cloud (api.firecrawl.dev) and self-hosted instances. The server reads FIRECRAWL_API_KEY for cloud authentication and FIRECRAWL_API_URL to override the default endpoint. Additional env vars control retry behavior (FIRECRAWL_RETRY_*), credit monitoring thresholds (FIRECRAWL_CREDIT_WARNING_THRESHOLD, FIRECRAWL_CREDIT_CRITICAL_THRESHOLD), and transport selection. No config files or code changes required for deployment variations.

Solves for

I want to deploy the same server code to cloud and self-hosted Firecrawl instancesI need to configure retry and credit monitoring without editing codeI want to switch API endpoints based on environment (dev/staging/prod)

Best for

teams deploying across multiple environments (cloud, self-hosted, staging)

operators managing Firecrawl infrastructure and needing flexible configuration

CI/CD pipelines requiring environment-specific deployments

Requires

FIRECRAWL_API_KEY (for cloud) or FIRECRAWL_API_URL (for self-hosted)

Optional: FIRECRAWL_RETRY_*, FIRECRAWL_CREDIT_* env vars

Environment variable management system (Docker, Kubernetes, .env files, etc.)

Limitations

All configuration is environment-based — no runtime config API

No validation of env vars at startup — invalid values may cause runtime failures

No config file support — large deployments must manage many env vars

What makes it unique

Supports both Firecrawl cloud and self-hosted instances via FIRECRAWL_API_URL override, with all configuration (retry, credits, transport) driven by environment variables, enabling single codebase deployment across cloud and on-premise infrastructure

vs alternatives

More flexible than hardcoded endpoints because FIRECRAWL_API_URL enables self-hosted switching; more portable than config files because env vars work across Docker, Kubernetes, and serverless platforms without file mounts

zod schema validation for tool parameters with type safety

Medium confidence

Validates all tool parameters using Zod v4.1.5 schemas defined in src/index.ts, ensuring type correctness and required field presence before submitting to Firecrawl API. Each of the 8 tools has a Zod schema (e.g., URL validation, format enum validation, schema object validation) that FastMCP applies automatically. Invalid parameters are rejected with descriptive error messages before API calls, reducing wasted requests and improving error clarity.

Solves for

I want type-safe tool invocation with clear error messages for invalid parametersI need to validate complex parameters (JSON schemas, URL formats) before API callsI want to prevent malformed requests from reaching the Firecrawl API

Best for

developers building agents that invoke Firecrawl tools programmatically

teams requiring strict input validation before API calls

workflows where parameter errors should fail fast with clear messages

Requires

Zod v4.1.5 (included in dependencies)

MCP client passing parameters as JSON

Limitations

Zod schemas are defined in code — no runtime schema modification

Validation errors are Zod-formatted — may be verbose for complex schemas

No custom validation logic — limited to Zod's built-in validators

What makes it unique

Uses Zod v4.1.5 schemas for all 8 Firecrawl tools, validating parameters before API submission and providing type-safe interfaces through MCP, reducing invalid requests and improving error clarity

vs alternatives

More robust than no validation because it catches errors before API calls; more flexible than TypeScript-only validation because Zod works with MCP's JSON-based parameter passing

web search with result ranking and snippet extraction

Medium confidence

Executes web searches via Firecrawl's search() method, returning ranked results with snippets, URLs, and metadata. The MCP server validates search query parameters using Zod schemas and applies exponential backoff retry logic (up to 3 attempts) on transient failures. Results are returned as a structured array suitable for LLM context injection or further processing.

Solves for

I need to find current information on the web to answer a user query in real-timeI want to discover relevant URLs before scraping them for detailed contentI need search results with snippets to feed into an LLM's reasoning loop

Best for

LLM agents needing real-time web knowledge (news, pricing, availability)

research workflows combining search discovery with content extraction

applications requiring current information beyond training data cutoff

Requires

FIRECRAWL_API_KEY (cloud) or FIRECRAWL_API_URL (self-hosted)

Search query string (required)

MCP client with tool-calling capability

Limitations

Search quality depends on Firecrawl's underlying search provider (not disclosed in docs)

No advanced query syntax support (boolean operators, site: filters) — simple keyword search only

Result ranking is provider-dependent, not customizable

What makes it unique

Wraps Firecrawl's search() API through MCP protocol with Zod parameter validation and automatic exponential backoff, enabling LLM clients to invoke web search without managing HTTP clients or retry logic, integrated seamlessly with scraping tools for discovery-to-extraction workflows

vs alternatives

Simpler than integrating multiple search APIs (Google, Bing, DuckDuckGo) because Firecrawl abstracts provider selection; more reliable than raw API calls because MCP+FastMCP handles transport and retry automatically

site url discovery and mapping via crawl indexing

Medium confidence

Maps all discoverable URLs on a domain using Firecrawl's mapUrl() method, which crawls the site structure and returns a flat list of URLs. The server wraps this with Zod validation and exponential backoff retry (up to 3 attempts). Useful for discovering site structure before selective scraping or batch operations. Returns a simple URL array without content.

Solves for

I need to discover all pages on a website before deciding which to scrapeI want to generate a sitemap-like structure for a domain programmaticallyI need to find all product pages or documentation pages on a site

Best for

agents performing site reconnaissance before targeted scraping

workflows needing dynamic site structure discovery (no manual URL lists)

teams building web crawlers that adapt to site layout changes

Requires

FIRECRAWL_API_KEY (cloud) or FIRECRAWL_API_URL (self-hosted)

Valid domain URL (required)

Reasonable site size (typically <5000 pages for reliable results)

Limitations

Returns URLs only — no content, metadata, or hierarchy information

Crawl depth and breadth limited by Firecrawl's crawl timeout and resource limits

May miss dynamically-generated URLs (JavaScript-rendered content depends on Firecrawl's JS rendering capability)

What makes it unique

Exposes Firecrawl's mapUrl() through MCP with automatic retry logic, enabling agents to dynamically discover site structure without manual URL lists or sitemaps, paired with batch scraping for efficient multi-page extraction workflows

vs alternatives

More dynamic than static sitemaps because it discovers actual crawlable URLs; more efficient than sequential scraping because it identifies targets before extraction, reducing wasted API calls on non-existent pages

structured data extraction with json schema validation

Medium confidence

Extracts structured data from web pages using Firecrawl's extract() method with user-defined JSON schemas. The server accepts a URL and a Zod-validated schema parameter, sends both to Firecrawl's LLM-powered extraction engine, and returns parsed JSON matching the schema. Includes exponential backoff retry (up to 3 attempts) and validates schema format before submission.

Solves for

I need to extract specific fields (price, rating, availability) from product pagesI want to parse unstructured web content into a structured JSON format for database insertionI need to extract multiple data points from a page using a predefined schema

Best for

data extraction pipelines requiring structured output (e-commerce, real estate, job boards)

teams building web-to-database workflows without manual parsing

agents needing to normalize heterogeneous web content into consistent schemas

Requires

FIRECRAWL_API_KEY (cloud) or FIRECRAWL_API_URL (self-hosted)

URL string (required)

JSON Schema object defining extraction structure (required)

Limitations

Schema complexity affects extraction accuracy — overly complex schemas may fail or hallucinate

LLM-based extraction is non-deterministic — same page may yield slightly different results on retry

No validation that extracted data matches real page content — relies on Firecrawl's LLM accuracy

What makes it unique

Wraps Firecrawl's LLM-powered extract() method through MCP with Zod schema validation for parameters, enabling agents to define extraction schemas declaratively and receive structured JSON without writing parsing logic, integrated with retry logic for reliability

vs alternatives

More flexible than regex-based extraction because it understands semantic content; more reliable than manual CSS selectors because it uses LLM reasoning to find data even when page structure changes, though less deterministic than rule-based approaches

multi-page site crawling with asynchronous job management

Medium confidence

Initiates a full-site crawl via Firecrawl's crawlUrl() method, returning a job_id immediately for asynchronous processing. The server does not block — clients must poll firecrawl_check_crawl_status with the job_id to retrieve crawl progress and results. Internally applies exponential backoff retry on job submission. Crawls respect robots.txt and site rate limits configured in Firecrawl.

Solves for

I need to crawl an entire website and extract all content for indexing or analysisI want to submit a large crawl job and check progress without blocking my agentI need to archive or analyze all pages on a domain systematically

Best for

large-scale content extraction (100+ pages per site)

workflows where crawl latency is acceptable and async polling is feasible

teams building web archival or competitive intelligence systems

Requires

FIRECRAWL_API_KEY (cloud) or FIRECRAWL_API_URL (self-hosted)

Valid domain URL (required)

Client-side polling mechanism to check crawl status periodically

Limitations

Asynchronous only — returns job_id immediately, requires polling for results

No streaming results — must wait for crawl completion before accessing content

Crawl timeout and depth limits enforced by Firecrawl (typically 30min timeout, configurable depth)

What makes it unique

Implements fire-and-forget crawl submission via MCP, returning job_id immediately without blocking, paired with firecrawl_check_crawl_status for polling — enables agents to initiate large crawls and continue reasoning while Firecrawl processes pages server-side

vs alternatives

More efficient than sequential page scraping because Firecrawl crawls in parallel server-side; more flexible than synchronous crawl APIs because clients control polling frequency and can interleave other work without blocking

asynchronous batch status polling with result aggregation

Medium confidence

Polls the status of a previously-submitted batch scraping job using firecrawl_check_batch_status, accepting a batch_id and returning completion percentage, processed URLs, and result data. The server wraps Firecrawl's SDK status check with Zod validation and exponential backoff retry (up to 3 attempts). Enables non-blocking result retrieval for fire-and-forget batch submissions.

Solves for

I submitted a batch scrape job and need to check if it's doneI want to retrieve results from a batch job without re-submittingI need to monitor progress of a large batch operation

Best for

agents implementing polling loops for batch jobs

workflows where batch results are retrieved asynchronously after submission

teams monitoring long-running scraping operations

Requires

batch_id string from prior firecrawl_batch_scrape call (required)

FIRECRAWL_API_KEY (cloud) or FIRECRAWL_API_URL (self-hosted)

MCP client with tool-calling capability

Limitations

Requires valid batch_id from prior firecrawl_batch_scrape call — cannot discover batch IDs

Batch jobs expire after Firecrawl's retention period (typically 24-48 hours)

Status checks consume API quota — frequent polling may incur unnecessary costs

What makes it unique

Exposes Firecrawl's batch status API through MCP with Zod validation and exponential backoff, enabling agents to poll batch job progress without managing HTTP clients or retry logic, paired with firecrawl_batch_scrape for complete async batch workflows

vs alternatives

Simpler than building custom polling logic because MCP standardizes the interface; more reliable than raw SDK calls because FastMCP handles transport and retry automatically

asynchronous crawl status polling with progress tracking

Medium confidence

Polls the status of a previously-submitted site crawl job using firecrawl_check_crawl_status, accepting a job_id and returning crawl progress, completed page count, and result URLs. The server wraps Firecrawl's SDK status check with Zod validation and exponential backoff retry (up to 3 attempts). Enables non-blocking result retrieval for fire-and-forget crawl submissions.

Solves for

I submitted a site crawl and need to check progress without blockingI want to retrieve crawl results once the job completesI need to monitor a long-running crawl operation and react when done

Best for

agents implementing polling loops for crawl jobs

workflows where crawl results are retrieved asynchronously after submission

teams monitoring large site crawls with progress feedback

Requires

job_id string from prior firecrawl_crawl call (required)

FIRECRAWL_API_KEY (cloud) or FIRECRAWL_API_URL (self-hosted)

MCP client with tool-calling capability

Limitations

Requires valid job_id from prior firecrawl_crawl call — cannot discover job IDs

Crawl jobs expire after Firecrawl's retention period (typically 24-48 hours)

Status checks consume API quota — frequent polling may incur unnecessary costs

What makes it unique

Exposes Firecrawl's crawl status API through MCP with Zod validation and exponential backoff, enabling agents to poll crawl progress without managing HTTP clients or retry logic, paired with firecrawl_crawl for complete async crawl workflows

vs alternatives

Simpler than building custom polling logic because MCP standardizes the interface; more reliable than raw SDK calls because FastMCP handles transport and retry automatically

mcp protocol bridging with multi-transport support

Medium confidence

Implements a FastMCP server that bridges MCP clients (Cursor, Claude Desktop, VS Code) with Firecrawl APIs using the Model Context Protocol. The server supports three transport mechanisms: stdio (default for local clients), SSE (Server-Sent Events for HTTP), and HTTP (for REST-style clients). Built on firecrawl-fastmcp v1.0.4 framework, it handles tool registration, parameter validation via Zod schemas, and transport negotiation automatically. Clients connect via configured transport and invoke tools as standardized MCP resources.

Solves for

I want to use Firecrawl tools directly in Cursor or Claude Desktop without API wrappersI need to expose Firecrawl as a local MCP server for my LLM clientI want to integrate web scraping into my agent without managing HTTP clients

Best for

developers using Cursor, Claude Desktop, or VS Code with MCP support

teams building LLM agents that need web scraping capabilities

organizations deploying Firecrawl as a local service for multiple clients

Requires

Node.js 18+ runtime

MCP-compatible client (Cursor, Claude Desktop, VS Code with MCP extension)

FIRECRAWL_API_KEY environment variable (cloud) or FIRECRAWL_API_URL (self-hosted)

Limitations

Requires MCP-compatible client — not compatible with standard REST API consumers

Transport selection is fixed at server startup — cannot switch transports dynamically

No built-in authentication beyond API key — relies on Firecrawl API key for security

What makes it unique

Implements FastMCP server with automatic tool registration, Zod parameter validation, and multi-transport support (stdio/SSE/HTTP), enabling seamless integration with Cursor, Claude Desktop, and other MCP clients without custom transport code

vs alternatives

More integrated than raw Firecrawl SDK because MCP standardizes the interface across clients; more flexible than REST wrappers because it supports multiple transports and handles protocol negotiation automatically

exponential backoff retry with configurable rate-limit handling

Medium confidence

Implements automatic retry logic for all Firecrawl API calls using exponential backoff with configurable delays and multipliers. The server reads FIRECRAWL_RETRY_* environment variables (FIRECRAWL_RETRY_MAX_ATTEMPTS, FIRECRAWL_RETRY_INITIAL_DELAY, FIRECRAWL_RETRY_MAX_DELAY, FIRECRAWL_RETRY_BACKOFF_FACTOR) and applies them uniformly across all tools. Retries on transient failures (rate limits, timeouts) but fails fast on permanent errors (auth, invalid input). Delays grow exponentially: initial_delay * (backoff_factor ^ attempt_number), capped at max_delay.

Solves for

I need reliable API calls that automatically retry on transient failuresI want to tune retry behavior for my rate limit and latency constraintsI need to handle Firecrawl API rate limiting without manual retry logic

Best for

production agents requiring high reliability

teams with strict rate limits needing adaptive retry tuning

workflows where transient failures are expected and acceptable

Requires

Environment variables: FIRECRAWL_RETRY_MAX_ATTEMPTS (default 3), FIRECRAWL_RETRY_INITIAL_DELAY (default 1000ms), FIRECRAWL_RETRY_MAX_DELAY (default 10000ms), FIRECRAWL_RETRY_BACKOFF_FACTOR (default 2)

Limitations

Retry logic is global — cannot be tuned per-tool or per-request

Exponential backoff may introduce significant latency for high max_delay values

No jitter — retries use deterministic delays, which can cause thundering herd in concurrent scenarios

What makes it unique

Implements configurable exponential backoff via environment variables (FIRECRAWL_RETRY_*) applied uniformly across all 8 Firecrawl tools, enabling operators to tune retry behavior without code changes or per-tool configuration

vs alternatives

More flexible than fixed retry policies because operators can adjust delays and multipliers; more reliable than no retry because it handles transient failures automatically without client-side logic

Crawl timeout and depth limits enforced by Firecrawl (typically 30min timeout, configurable depth)

What makes it unique

vs alternatives

asynchronous batch status polling with result aggregation

Medium confidence

Solves for

I submitted a batch scrape job and need to check if it's doneI want to retrieve results from a batch job without re-submittingI need to monitor progress of a large batch operation

Best for

agents implementing polling loops for batch jobs

workflows where batch results are retrieved asynchronously after submission

teams monitoring long-running scraping operations

Requires

batch_id string from prior firecrawl_batch_scrape call (required)

FIRECRAWL_API_KEY (cloud) or FIRECRAWL_API_URL (self-hosted)

MCP client with tool-calling capability

Limitations

Requires valid batch_id from prior firecrawl_batch_scrape call — cannot discover batch IDs

Batch jobs expire after Firecrawl's retention period (typically 24-48 hours)

Status checks consume API quota — frequent polling may incur unnecessary costs

What makes it unique

vs alternatives

Simpler than building custom polling logic because MCP standardizes the interface; more reliable than raw SDK calls because FastMCP handles transport and retry automatically

asynchronous crawl status polling with progress tracking

Medium confidence

Solves for

I submitted a site crawl and need to check progress without blockingI want to retrieve crawl results once the job completesI need to monitor a long-running crawl operation and react when done

Best for

agents implementing polling loops for crawl jobs

workflows where crawl results are retrieved asynchronously after submission

teams monitoring large site crawls with progress feedback

Requires

job_id string from prior firecrawl_crawl call (required)

FIRECRAWL_API_KEY (cloud) or FIRECRAWL_API_URL (self-hosted)

MCP client with tool-calling capability

Limitations

Requires valid job_id from prior firecrawl_crawl call — cannot discover job IDs

Crawl jobs expire after Firecrawl's retention period (typically 24-48 hours)

Status checks consume API quota — frequent polling may incur unnecessary costs

What makes it unique

vs alternatives

Simpler than building custom polling logic because MCP standardizes the interface; more reliable than raw SDK calls because FastMCP handles transport and retry automatically

mcp protocol bridging with multi-transport support

Medium confidence

Solves for

Best for

developers using Cursor, Claude Desktop, or VS Code with MCP support

teams building LLM agents that need web scraping capabilities

organizations deploying Firecrawl as a local service for multiple clients

Requires

Node.js 18+ runtime

MCP-compatible client (Cursor, Claude Desktop, VS Code with MCP extension)

FIRECRAWL_API_KEY environment variable (cloud) or FIRECRAWL_API_URL (self-hosted)

Limitations

Requires MCP-compatible client — not compatible with standard REST API consumers

Transport selection is fixed at server startup — cannot switch transports dynamically

No built-in authentication beyond API key — relies on Firecrawl API key for security

What makes it unique

vs alternatives

exponential backoff retry with configurable rate-limit handling

Medium confidence

Solves for

Best for

production agents requiring high reliability

teams with strict rate limits needing adaptive retry tuning

workflows where transient failures are expected and acceptable

Requires

Limitations

Retry logic is global — cannot be tuned per-tool or per-request

Exponential backoff may introduce significant latency for high max_delay values

No jitter — retries use deterministic delays, which can cause thundering herd in concurrent scenarios

What makes it unique

vs alternatives

More flexible than fixed retry policies because operators can adjust delays and multipliers; more reliable than no retry because it handles transient failures automatically without client-side logic
