プロジェクトの歴史

The public repository was created in December 2024, early in the wave of small utilities that filled gaps between rapidly changing MCP client and server transport support. Its README defines two core modes: stdio to SSE/Streamable HTTP and SSE to stdio.

As MCP moved beyond purely local stdio servers, mcp-proxy became a practical compatibility layer rather than a general-purpose network proxy. The README is careful to frame it as a transport switcher for MCP clients and servers, with command-line options for headers, OAuth client credentials, CORS, named servers, and environment passing.

採用の歴史

The project is packaged on PyPI, can be installed with uv or pipx, and is also available through Homebrew and Nix according to the input package facts. That mix made it convenient for both Python tool users and package-manager users who wanted a stable `mcp-proxy` command.

GitHub metadata showed thousands of stars and hundreds of forks by July 2026, and the release feed showed continued 0.x releases into 2026. That adoption pattern matches its niche: a small command-line compatibility tool that becomes widely referenced while clients catch up with newer MCP transports.

使われ方

In stdio-to-remote mode, users place `mcp-proxy` in an MCP client configuration and pass the remote SSE endpoint or Streamable HTTP endpoint as an argument. The README documents optional authorization headers and an `API_ACCESS_TOKEN` environment variable for bearer-token scenarios.

In remote-to-stdio mode, users run `mcp-proxy` with a local MCP server command and a listening port, optionally defining named servers in JSON. This lets remote clients reach local stdio MCP servers at URL paths such as `/servers/<name>/`.

パッケージ好きにとっての重要性

mcp-proxy matters to package users because it turns transport support into a package-manager-installable shim. Instead of waiting for every MCP client to support every transport, users can install one CLI and keep existing server packages unchanged.

It is also a good example of the MCP ecosystem's early packaging style: small, single-purpose CLIs distributed through language-native channels first, then wrapped by system package managers once they become common glue in user configurations.
