Starlette MCP SSE

What is Starlette MCP SSE?

It is a Server-Sent Events (SSE) implementation using the Starlette framework with Model Context Protocol (MCP) integration. The project demonstrates how to add MCP SSE endpoints to a Starlette web application while keeping standard web routes separate.

How to use Starlette MCP SSE?

You can run the server without cloning via uvx --from git+https://github.com/panz2018/starlette_mcp_sse.git start, or install fully with uv venv, activate it, install dependencies with uv pip install -r pyproject.toml, then start with python src/server.py or uv run start. After startup, the SSE endpoint is at /sse and message endpoint at /messages/. Debug using MCP Inspector with the mcp dev ./src/weather.py command and connect at http://localhost:8000/sse.

Key features of Starlette MCP SSE

• Server-Sent Events (SSE) implementation with MCP
• Starlette framework integration with custom routes
• Unified web application with both MCP and standard web endpoints
• Customizable route structure
• Clean separation of concerns between MCP and web functionality
