Toolport

Every MCP client keeps its own copy of your server list. Add a database server to Claude Code and you add it again in Cursor, again in VS Code, again in Codex — four config files, four copies of the same credentials, and four chances to get one of them wrong. Toolport replaces that with a single local gateway: you register each MCP server once, and every agent on the machine connects to Toolport instead.

Lazy tool discovery, not a wall of definitions

The more interesting half is what it does to context. A conventional setup dumps the full tool definitions of every connected server into the model's context on each request, whether or not the task needs them. Toolport exposes a small set of meta-tools instead and loads the real definitions only when the agent goes looking. The project's published benchmark puts the difference at roughly 23,700 tokens down to 886 per request — the basis for its claim of up to 91% fewer tool tokens at the same task success rate.

Runs locally, keeps secrets local

There is no account and no cloud component. Toolport is a desktop application for Windows, macOS and Linux; server credentials live in the operating system keychain rather than in a plaintext JSON file in your home directory. Tool-integrity checking watches for definitions that change after you approve them, which is the practical defence against a server silently swapping a benign tool for a destructive one — and destructive calls can be gated behind human approval.

Observability and team use

A built-in dashboard reports per-server latency, error rates and a full audit trail of what each client called. Toolport for Teams adds shared server catalogues, member management and usage reporting, free for up to five people.

Licence and clients

MIT-licensed and open source. Documented clients include Claude Code, Claude Desktop, Cursor, VS Code, Windsurf, Codex and Antigravity, plus anything else that speaks standard MCP. Version 1.11.0 added support for the 2026-07-28 MCP specification's streamable HTTP transport, including sessionless requests and multi-round-trip approvals.
