Toolport

Toolport is a free, open-source, local-first MCP gateway. Set up and authenticate each MCP server once, and every AI client (Claude, Cursor, VS Code, Codex and the rest) shares it. Your agent loads a handful of meta-tools instead of hundreds, cutting tool-token overhead up to 91%. Every call is fingerprinted for tampering, your API keys stay in the OS keychain, and you get a full audit trail. No containers, no sign-up.

What to expect from an ideal product

  1. Toolport acts as a single local MCP gateway, so you configure Claude, Cursor, VS Code, and Codex once instead of re-authenticating each MCP server per client every time your setup changes.
  2. Instead of loading hundreds of individual tools into context, Toolport serves a small set of meta-tools that proxy requests on demand, cutting tool-token overhead by up to 91% and leaving more context window for actual work.
  3. API keys never leave your machine β€” Toolport stores credentials in the OS keychain and fingerprints every tool call to detect tampering, giving teams an audit trail without routing traffic through a third-party server.
  4. There are no Docker containers to manage, no cloud account to create, and no background service to babysit β€” Toolport runs locally, installs without ceremony, and works across MCP-compatible clients out of the box.
  5. For developers running multiple MCP servers simultaneously (filesystem, GitHub, Postgres, browser automation), Toolport eliminates the per-client duplication problem and makes adding a new AI client a one-line config change instead of a full re-setup.
