mcp-combiner

An MCP aggregator — fronts multiple MCP servers behind a single Streamable HTTP endpoint, so one connection exposes every backend server's tools. Built on FastMCP. Shareable across clients (via sharedserver), it powers the mcp-companion Neovim plugin and the claude-mcp-combiner Claude Code plugin, and works standalone with any MCP client.

PyPI package · command · import package: mcp-combiner / mcp-combiner / mcp_combiner.

⚠️ Renamed from mcp-bridge. If you ran an earlier build:

  • command/import are now mcp-combiner / mcp_combiner; reinstall: uv tool uninstall mcp-bridge then uv tool install … (see Install below).
  • config env vars MCP_BRIDGE_* → MCP_COMBINER_* (and MCP_COMPANION_COMBINER_URL → MCP_COMPANION_COMBINER_URL).
  • OAuth token storage moved to ~/.cache/mcp-combiner/ — you'll re-authenticate each MCP server once (old tokens under ~/.cache/mcp-companion/ are no longer read).

Install

Needs only uv — uvx fetches and runs it, no venv to manage:

uvx mcp-combiner --help                                                # once published to PyPI
# before PyPI (or to track main) — the package lives in the combiner/ subdirectory:
uvx --from "git+https://github.com/georgeharker/mcp-companion#subdirectory=combiner" mcp-combiner

Or install it: uv pip install mcp-combiner (PyPI), or from the repo subdir uv pip install "git+https://github.com/georgeharker/mcp-companion#subdirectory=combiner".

Usage

mcp-combiner --config /path/to/servers.json --port 9741
