Use MCP servers in Pi with Toolport
Toolport is a free, open source local MCP gateway. Add your servers to Toolport once, flip the Pi toggle, and Pi gets all of them through a single gateway entry. Toolport picks a full tool list or search for each client, and you can change it in Clients.
Setup
- Download Toolport for Windows, macOS or Linux, and add your MCP servers to it (or import the ones your other AI agents already have; secrets go to your OS keychain).
- Open the Clients tab and toggle Pi on. Toolport writes its gateway entry into Pi's config, next to anything already there.
- Restart or reload Pi. Your full server set is available through Toolport, and any server you add later shows up without touching Pi again.
Where Pi keeps its MCP config
Pi MCP config
All platforms ~/.pi/agent/mcp.json
JSON with a top-level mcpServers object.
Good to know
- Toolport leaves Pi's optional lifecycle and idleTimeout keys unset, so the gateway entry uses Pi's own defaults.
Why a gateway instead of Pi's own server list?
- One setup, every agent. The same servers work in Pi and every other AI agent on your machine; add a server once and they all get it.
- Secrets in the OS keychain. API keys are injected at runtime and never sit in Pi's config file.
- Watched by default. Rug-pull and tool-poisoning detection on every tool, plus per-tool governance and a destructive-tool kill switch. How the security works.
Free on this machine. Pro puts it on every machine. Team gives it to everyone.
