Automatically generates MCP tool definitions at server startup by parsing the Notion OpenAPI specification (notion-openapi.json), eliminating manual tool definition and ensuring 100% API surface coverage. The MCPProxy class reads the OpenAPI schema, converts each operation into an MCP tool with proper parameter schemas and descriptions, and registers them in the tool registry for client discovery. This approach keeps tools synchronized with Notion API updates without code changes.
Unique: Uses declarative OpenAPI-to-MCP conversion at startup rather than hardcoded tool definitions, enabling zero-maintenance API surface exposure. The MCPProxy translates OpenAPI operations directly to MCP tool schemas with parameter validation, avoiding the need for manual tool registration code.
vs alternatives: Faster to maintain than hand-coded tool definitions and automatically covers new Notion API endpoints without code changes, unlike static MCP server implementations that require manual updates for each API operation.
Implements both STDIO (for desktop AI clients like Claude Desktop, Cursor, Zed) and HTTP (for web-based applications) transport layers through MCP SDK abstractions, allowing a single server binary to serve different client types. The transport layer is selected at startup via CLI arguments and environment configuration, with the server automatically handling protocol-specific serialization, framing, and error handling. This enables deployment flexibility without maintaining separate server implementations.
Unique: Abstracts transport differences through MCP SDK's transport layer, allowing a single codebase to serve STDIO and HTTP clients without conditional logic in the core MCPProxy. The transport is injected at initialization, making the protocol bridge transport-agnostic.
vs alternatives: More flexible than single-transport MCP servers (e.g., STDIO-only implementations) because it supports both desktop and web clients from one deployment, and more maintainable than separate server implementations because transport logic is centralized in the SDK.
Retrieves the schema of a Notion database, including all properties (columns), their types (text, select, date, relation, etc.), and configuration (options for select properties, relation targets, etc.). This capability enables AI clients to discover what properties exist in a database and their constraints before querying or updating rows. The introspection tool fetches the database object from the Notion API and extracts the properties schema.
Unique: Exposes Notion's database schema through MCP tool interface, allowing AI agents to dynamically discover property types and constraints without hardcoding schema knowledge. This enables adaptive database interactions.
vs alternatives: More flexible than hardcoded schema because it adapts to database changes, but requires additional API calls and adds latency compared to pre-configured schema knowledge.
Updates specific properties of a Notion page (when the page is part of a database) with type-aware value conversion, handling different property types (text, select, date, relation, checkbox, etc.) and converting input values to Notion's internal format. The update page properties tool accepts a page ID and a properties object, validates values against the property schema, converts them to Notion format, and sends a PATCH request. This enables AI agents to update database rows without needing to know Notion's internal property value representation.
Unique: Implements type-aware property value conversion, translating user-friendly values (e.g., 'Done', '2025-01-15') to Notion's internal property format (select IDs, ISO dates) without requiring clients to know the conversion rules. The implementation validates values against the database schema.
vs alternatives: More user-friendly than raw Notion API calls because it handles type conversion automatically, but requires schema knowledge to validate values and may not support all complex property types that the raw API supports.
Deletes a Notion page and optionally its nested content (child blocks, database rows) through the Notion API. The delete page tool accepts a page ID and an optional cascade flag, constructs a DELETE request, and removes the page from the workspace. This enables AI agents to clean up pages or remove outdated content programmatically.
Unique: Exposes Notion's page deletion API through MCP tool interface, allowing AI agents to remove pages programmatically. The implementation handles the permanent nature of deletion and provides clear feedback.
vs alternatives: Simpler than manual deletion through the Notion UI, but more dangerous because deletion is permanent and cannot be undone through the API, unlike the UI which provides a trash/recovery mechanism.
Initializes the MCP server by parsing command-line arguments (transport type, port, API token), loading the OpenAPI specification, initializing the MCPProxy with converted tool definitions, creating the appropriate transport layer (STDIO or HTTP), and starting the server. The startup process is orchestrated by the CLI binary (bin/cli.mjs) which delegates to scripts/start-server.ts. This capability handles all initialization logic needed to bring the server from startup to ready-to-accept-connections state.
Unique: Orchestrates multi-step initialization (OpenAPI loading, MCPProxy creation, transport setup) through a single CLI entry point, with configuration driven by command-line arguments and environment variables. The startup process is designed for containerized deployment.
vs alternatives: Simpler to deploy than servers requiring complex configuration files because it uses CLI arguments and environment variables, but less flexible than servers supporting configuration files or dynamic reconfiguration.
Each MCP tool invocation is independently stateless, with authentication credentials (Notion API token) managed via environment variables rather than session state or connection-level auth. When a client calls a tool, the HttpClient retrieves the API key from the environment, constructs the HTTP request with proper headers, executes it against the Notion API, and returns the response without maintaining any inter-request state. This design simplifies deployment and scaling but requires the API token to be available in every server instance's environment.
Unique: Implements strict statelessness where each tool call is independent and authenticated via environment variables, avoiding session management complexity. The HttpClient is instantiated fresh per request with credentials from the environment, making the server horizontally scalable without shared state.
vs alternatives: Simpler to deploy than stateful MCP servers that maintain connection pools or session caches, and more suitable for serverless/containerized environments, but less flexible than servers supporting per-user authentication or token refresh mechanisms.
The MCPProxy class translates between MCP's tool-based abstraction (listTools, callTool methods) and Notion's REST API operations by mapping MCP tool parameters to HTTP request components (URL, method, headers, body). When a client calls an MCP tool, MCPProxy converts the tool name and parameters into an HTTP request using the OpenAPI schema, executes it via HttpClient, and converts the HTTP response back into MCP tool result format. This translation layer abstracts away HTTP details from the MCP client.
Unique: Implements bidirectional protocol translation in MCPProxy where MCP tool calls are converted to HTTP requests using OpenAPI schema as the mapping source, and HTTP responses are converted back to MCP results. This eliminates the need for manual request/response handling code.
vs alternatives: More maintainable than hardcoded HTTP client code because the translation logic is driven by OpenAPI schema, and more flexible than direct REST API clients because it abstracts HTTP details behind the MCP tool interface.

Translates conversational task descriptions into structured Todoist API calls by parsing natural language for task content, due dates (e.g., 'tomorrow', 'next Monday'), priority levels (1-4 semantic mapping), and optional descriptions. Uses date recognition to convert human-readable temporal references into ISO format and priority mapping to interpret semantic priority language, then submits via Todoist REST API with full parameter validation.
Unique: Implements semantic date and priority parsing within the MCP tool handler itself, converting natural language directly to Todoist API parameters without requiring a separate NLP service or external date parsing library, reducing latency and external dependencies
vs alternatives: Faster than generic task creation APIs because date/priority parsing is embedded in the MCP handler rather than requiring round-trip calls to external NLP services or Claude for parameter extraction
Queries Todoist tasks using natural language filters (e.g., 'overdue tasks', 'tasks due this week', 'high priority tasks') by translating conversational filter expressions into Todoist API filter syntax. Supports partial name matching for task identification, date range filtering, priority filtering, and result limiting. Implements filter translation logic that converts semantic language into Todoist's native query parameter format before executing REST API calls.
Unique: Translates natural language filter expressions (e.g., 'overdue', 'this week') directly into Todoist API filter parameters within the MCP handler, avoiding the need for Claude to construct API syntax or make multiple round-trip calls to clarify filter intent
vs alternatives: More efficient than generic task APIs because filter translation is built into the MCP tool, reducing latency compared to systems that require Claude to generate filter syntax or make separate API calls to validate filter parameters
Notion MCP Server scores higher at 46/100 vs Todoist MCP Server at 46/100.
