Pi.dev adds MCP to core: 'You Said No MCP'

Pi.dev reverses its public no-MCP stance, integrating Model Context Protocol into the core of its agentic coding platform with a 'Codemode' sandbox for tool composition.

Why it matters

A flagship agent platform admitting MCP won - plus its Codemode sandbox reframes MCP tools as composable OpenAPI-style endpoints, which could reshape how small harnesses consume tools.

What you could build with it

A dev-tools team could build an MCP-gateway service exposing a company's internal APIs as Pi-compatible tools, letting small coding agents compose enterprise workflows without custom glue code.

Does it hold up?

Too early to judge the MCP integration itself (announced Sep 29), but the base platform has real third-party adoption - ComfyUI and disclaude both built on pi's documented JSON event stream.
