About fastify-mcp

fastify-mcp

See the examples directory for more detailed examples.

Installation

Session Management

The official MCP TypeScript SDK does not support managing multiple sessions out of the box, and therefore it's the host server's responsibility to do so.

This package uses an in-memory mapping of each active session against its session ID to manage multiple sessions, as recommended by the MCP SDK examples.

Session Events

The Sessions class emits the following events:

• connected: Emitted when a new session is added. • terminated: Emitted when a session is removed. • error: Emitted when an asynchronous event handler throws an error.

Contributing

Please file an issue if you encounter a problem when using this package. Pull requests for new features or bug fixes are also welcome.
