Typed, sandboxed Code Mode access to configured MCP servers for Pi

About pi-codemcp

Fast, typed, sandboxed Code Mode for every MCP server configured in Pi.

Instead of putting every upstream MCP tool definition into the model context, pi-codemcp gives the agent a small interface for discovery, execution, and reuse:

- codemcpsearch ranks capabilities or pages through a compact inventory without loading full schemas. - codemcpinspect returns exact typed SDK stubs only for selected calls. - codemcpexecute runs one sandboxed Python call graph across one or many MCP servers. - codemcpsavechain turns a repeated call graph into a reusable native Pi tool. - codemcpmanagechains lists chains or performs an explicitly confirmed enable, disable, revalidate, or delete.

Intermediate results stay inside the sandbox. The model receives only the compact value returned by the program.

MCP has an uncomfortable scaling property: the more tools an agent can use, the more tool schemas compete with the actual task for context. Multi-step work also tends to bounce every intermediate result through the model, adding tokens, latency, and opportunities for mistakes.

Cloudflare described a better pattern in Code Mode: give agents an entire API in 1,000 tokens: expose a small search-and-execute surface, let the model write code against a typed SDK, and execute that code in a sandbox. Their work reports a fixed tool footprint and dramatic context savings for very large APIs. The open-source implementation lives in @cloudflare/codemode.
