FastMCP Remote Proxy

This project exposes the tools from the remote FastMCP server through a local proxy. The upstream server uses Streamable HTTP and requires OAuth authentication.

Requirements

• Python 3.11 or newer

• uv

Related MCP server: mcp-server-proxy

Setup

uv sync

To create the project from scratch instead:

uv init
uv add fastmcp

Run With Inspector

Start the local MCP Inspector with:

uv run fastmcp dev main.py

The first run opens a browser for OAuth sign-in. Complete the login, then open the Inspector at http://127.0.0.1:6274 and refresh the connection.

FastMCP discovers the server through the standard mcp variable in main.py. The entrypoint can also be specified explicitly:

uv run fastmcp dev main.py:mcp

Run As A Local Stdio Server

uv run main.py

This starts the proxy over stdio for an MCP client such as Claude Desktop.

Publish Changes

git add .
git commit -m "Update FastMCP proxy"
git push

The upstream server is deployed through FastMCP Cloud.
