Exposes Open-Meteo weather API endpoints through the Model Context Protocol (MCP), allowing Claude and other MCP-compatible clients to query current weather, forecasts, and historical data without direct HTTP calls. Implements MCP resource and tool abstractions that translate natural language weather requests into Open-Meteo API parameters, handling coordinate lookup, unit conversion, and response formatting automatically.
Unique: Bridges Open-Meteo's free, open weather API directly into the MCP ecosystem, eliminating the need for custom HTTP client code in LLM applications. Uses MCP's tool and resource abstractions to expose weather queries as first-class capabilities that Claude can invoke naturally, with automatic parameter mapping and response normalization.
vs alternatives: Simpler than building custom REST API wrappers or weather plugins for each LLM framework because it leverages MCP's standardized tool-calling protocol, making it compatible with any MCP client without framework-specific adapters.
Translates human-readable location names (cities, regions, addresses) into latitude/longitude coordinates required by Open-Meteo's weather queries. Likely implements geocoding via Open-Meteo's Geocoding API or similar reverse-lookup service, handling ambiguous location names and returning ranked results so the LLM can disambiguate if needed.
Unique: Integrates geocoding as a transparent preprocessing step within the MCP protocol layer, so Claude can accept natural language locations without explicit coordinate parameters. Handles the full resolution pipeline (name → candidates → selection) within the MCP tool abstraction.
vs alternatives: More seamless than requiring users to manually specify coordinates or implement separate geocoding logic, because it's built into the MCP tool interface and handles disambiguation automatically through LLM reasoning.
Retrieves multi-day or hourly weather forecasts from Open-Meteo and formats them into structured, LLM-friendly representations. Handles variable selection (temperature, precipitation, wind, etc.), time-series aggregation, unit conversion (Celsius/Fahrenheit, metric/imperial), and response truncation to fit within LLM context windows. May implement caching of recent forecasts to reduce API calls.
Unique: Implements forecast aggregation and formatting as part of the MCP tool response pipeline, so Claude receives pre-processed, context-aware weather data rather than raw API responses. Likely includes intelligent variable selection and context-window-aware truncation to maximize relevance within LLM constraints.
vs alternatives: More efficient than having Claude parse raw Open-Meteo JSON responses because the MCP server handles formatting, unit conversion, and context optimization, reducing token overhead and improving response quality.
Provides access to historical weather records from Open-Meteo's archive, allowing queries for past weather conditions at any location and date. Implements time-range filtering, variable selection, and aggregation (daily, weekly, monthly summaries) to support weather analysis, trend detection, and climate pattern reasoning by LLMs.
Unique: Extends the MCP weather integration beyond real-time forecasts to include historical archives, enabling LLMs to perform temporal reasoning and trend analysis. Implements date-range filtering and aggregation within the MCP tool layer, abstracting Open-Meteo's historical API complexity.
vs alternatives: Provides historical context that real-time-only weather APIs lack, allowing Claude to perform comparative analysis and anomaly detection without requiring separate climate data sources or manual data aggregation.
Implements the MCP server-side tool registration and invocation framework, exposing weather capabilities as MCP tools that Claude and other MCP clients can discover and call. Handles tool schema definition (parameters, return types), request routing, error handling, and response serialization according to the MCP specification. Likely uses an MCP SDK or framework (e.g., mcp-python, mcp-node) to manage the protocol handshake and message passing.
Unique: Implements the MCP server-side framework that bridges Open-Meteo's REST API and Claude's tool-calling interface, handling all protocol-level concerns (schema registration, request routing, serialization) so weather tools appear as native capabilities to the LLM.
vs alternatives: Cleaner than custom REST API wrappers because MCP's standardized tool protocol eliminates the need for framework-specific adapters, making the server compatible with any MCP client without modification.
Automatically converts weather data between unit systems (Celsius/Fahrenheit, metric/imperial wind speeds, millimeters/inches precipitation) and formats output according to user preferences or locale. Implements unit mapping tables and conversion logic within the response formatting pipeline, ensuring Claude receives data in the requested system without manual transformation.
Unique: Integrates unit conversion and localization into the MCP response pipeline, so Claude receives pre-formatted data matching user preferences without needing to handle conversion logic. Supports both metric and imperial systems transparently.
vs alternatives: More user-friendly than requiring Claude to perform unit conversions in prompts because the MCP server handles all formatting, reducing token overhead and improving response consistency across different locales.
Implements robust error handling for Open-Meteo API failures, network timeouts, invalid location queries, and out-of-range date requests. Provides meaningful error messages to Claude and may implement fallback strategies (e.g., returning cached data, degrading to lower-resolution forecasts, or suggesting alternative locations). Handles MCP protocol errors and ensures the server remains stable under adverse conditions.
Unique: Implements error handling at the MCP server layer, ensuring Claude receives clear, actionable error messages and can decide whether to retry, use fallback data, or inform the user. Abstracts API-level failures from the LLM, improving robustness.
vs alternatives: More reliable than exposing raw API errors to Claude because the MCP server handles retries, caching, and error translation, reducing the likelihood of conversation failures due to transient API issues.
Analyzes forecast data to identify extreme weather conditions (severe storms, heat waves, cold snaps, high wind, etc.) based on configurable thresholds. Implements condition detection logic that flags dangerous weather patterns and returns structured alerts with severity levels, allowing agents to proactively warn users or trigger contingency workflows. Detection rules can be customized per location or use case.
Unique: Implements configurable alert detection on top of Open-Meteo forecast data within the MCP server, allowing Claude to request 'alerts for dangerous weather' as a single tool call rather than fetching raw forecast and implementing detection logic separately
vs alternatives: More integrated than requiring agents to implement alert logic themselves; more flexible than hardcoded alert rules because thresholds can be customized per use case
Executes SQL queries against Supabase PostgreSQL instances through the Model Context Protocol, translating natural language or structured query requests into parameterized SQL statements. Uses MCP's tool-calling interface to expose database operations as callable functions with schema validation, enabling LLM agents to perform CRUD operations, joins, and aggregations with automatic connection pooling and credential management through Supabase client SDK.
Unique: Exposes Supabase PostgreSQL as MCP tools with automatic credential injection from Supabase client SDK, eliminating manual connection string management and enabling seamless LLM-to-database queries within Claude or compatible agents
vs alternatives: Tighter integration than generic SQL MCP servers because it leverages Supabase's built-in authentication and connection pooling rather than requiring separate database credential configuration
Exposes Supabase Auth session state and user metadata through MCP tools, allowing agents to inspect current authentication context, retrieve user profiles, and trigger auth-related operations. Integrates with Supabase's JWT-based auth system to validate sessions and access user claims without re-authenticating, using the Supabase client's built-in session management.
Unique: Integrates Supabase's JWT-based auth system directly into MCP tool interface, allowing agents to inspect and act on auth state without managing separate credential stores or re-authentication flows
vs alternatives: More seamless than generic auth MCP servers because it leverages Supabase's built-in session management and avoids redundant credential passing between agent and auth system
Invokes Supabase Edge Functions (serverless TypeScript/JavaScript functions) through MCP tools, passing parameters and receiving results with optional streaming support. Uses Supabase's edge function HTTP API to trigger functions with automatic authentication headers and response parsing, enabling agents to execute custom business logic without embedding it in the agent itself.
Supabase scores higher at 42/100 vs open-meteo-mcp at 25/100. open-meteo-mcp leads on ecosystem, while Supabase is stronger on quality.

Performs semantic similarity searches on vector embeddings stored in Supabase PostgreSQL using pgvector extension, translating natural language queries into embedding vectors and executing cosine/L2 distance searches. Integrates with embedding providers (OpenAI, Cohere) or uses pre-computed embeddings, enabling agents to retrieve semantically similar documents or records without full-text search limitations.
Unique: Integrates pgvector directly into MCP tools with automatic embedding generation and distance calculation, enabling agents to perform semantic search without managing separate vector database infrastructure
vs alternatives: More efficient than external vector databases (Pinecone, Weaviate) for Supabase users because it colocates embeddings with relational data, reducing network latency and simplifying data synchronization
Exposes Supabase database schema information through MCP tools, allowing agents to discover table structures, column types, constraints, and relationships without manual schema documentation. Queries PostgreSQL information_schema and Supabase metadata tables to dynamically generate schema descriptions, enabling agents to construct valid queries and understand data relationships.
Unique: Queries Supabase's PostgreSQL information_schema directly through MCP tools, enabling agents to dynamically discover and adapt to database schemas without pre-configured schema definitions
vs alternatives: More flexible than static schema definitions because it reflects live database state, including recent migrations or schema changes
Enforces Supabase Row-Level Security policies within agent queries, ensuring that agents can only access rows permitted by RLS rules defined in the database. Evaluates policies based on authenticated user context (JWT claims, user ID) and applies WHERE clause filters automatically, preventing unauthorized data access at the database layer rather than application layer.
Unique: Delegates authorization enforcement to PostgreSQL RLS policies rather than implementing authorization in agent code, ensuring that data access rules are centralized and cannot be bypassed by agent logic
vs alternatives: More secure than application-level authorization because RLS is enforced at the database layer, preventing accidental data leaks even if agent code has bugs
