Overview

What is Fast MCP Server?

Fast MCP Server is a lightweight implementation of the Model Context Protocol (MCP) that exposes custom tools over Server-Sent Events (SSE) for integration with AI clients. It is designed for developers who need a simple, containerized MCP server with example tools like weather lookups.

How to use Fast MCP Server?

Clone the repository, then build and start the Docker container: docker compose build followed by docker compose up -d. Configure an MCP‑compatible client to connect via SSE at http://localhost:8100/sse. Customize the port or host by setting MCP_PORT and MCP_HOST environment variables in docker-compose.yml.

Key features of Fast MCP Server

Exposes tools as MCP endpoints over SSE
Containerized for quick deployment with Docker Compose
Configurable port and bind address
Includes example tools (weather alerts & forecast)
Simple JSON‑RPC communication over SSE

Use cases of Fast MCP Server

Add custom tool support to an MCP‑compatible AI client (e.g., Claude Desktop)
Deploy a lightweight MCP server for prototyping or testing
Run a containerized MCP server in development or CI pipelines
Extend with new tools by editing the Python source and rebuilding

Frequently asked questions

How do I connect an MCP client to Fast MCP Server?

Configure your client to use the SSE endpoint at `http://localhost:8100/sse`. For Claude Desktop, a sample configuration is provided in the `docs` folder.

How can I change the port or host?

Set the `MCP_PORT` and `MCP_HOST` environment variables in `docker-compose.yml` or directly in the container. Defaults are `8100` and `0.0.0.0`.

How do I add my own tools?

Edit `src/server.py` to define new MCP tools, then rebuild and restart the container with `docker compose build && docker compose up -d`.

What happens if I get a 404 on `/sse`?

Ensure the server is bound to the correct port and path. Check that the container is running with `docker ps` and inspect logs with `docker compose logs`.

What are the runtime requirements?

Docker ≥ 20.10 and Docker Compose ≥ 1.29. No other dependencies are needed.
