Pi adds MCP tools that can be composed in code

Pi now supports MCP, the protocol agents use to connect to external tools. Its Codemode lets the agent combine calls in a JavaScript sandbox, rather than repeatedly passing every intermediate result through the model. The announcement demonstrates combining Linear issue data with TypeSafe’s Jev classifier, making this a concrete integration example alongside the protocol change.

Why it matters

Agent developers get a practical example of composing data retrieval and classification.

More context

Try the updated Pi with a configured MCP server and a small read-only workflow. Jev requires separate provider access; TypeSafe still describes early access. Codemode state lives in the session transcript.

Keep in mind

The demonstration is from Pi’s developer, not an independent evaluation. Tool permissions and provider costs still apply. 1min has not run the integration.
