Todoist AI MCP server is a streamable HTTP service that lets AI agents search, fetch, and manage Todoist data through the MCP protocol. The server includes a focused set of tools designed to support complete Todoist workflows rather than single actions; notably, it provides search and fetch tools that follow the OpenAI MCP specification, delivering JSON-encoded results optimized for OpenAI clients while remaining compatible with the broader MCP ecosystem. The MCP server can be run directly with npx and is reachable at the primary URL https://ai.todoist.net/mcp, facilitating integration with a variety of AI clients including Claude Desktop, Cursor, Claude Code, and Visual Studio Code. In addition to its MCP capabilities, the server is designed to be reused as a library of tools that can be wired into other conversational interfaces outside the MCP setting. It relies on the official @modelcontextprotocol/sdk and the Todoist TypeScript API client to perform Todoist operations and includes references to docs for mcp-server.md and dev-setup.md to guide setup, testing, and local development. OAuth-based authentication flows enable Todoist access via browser-based sign-in through the various clients.
