Summary
Pi 1.0 supports MCP through Codemode, avoiding stuffing all tool definitions into model prompts and greatly reducing prompt token overhead. The article notes that Chrome DevTools MCP previously consumed about 18,000 tokens before any work began, roughly 9% of a 200K context window; Playwright MCP's…
Key points
- Helps developers understand the actual token cost of MCP tool definitions and how to reduce overhead and tighten permissions via an intermediary layer.
- Token overhead and tool permissions are two major obstacles to MCP reaching production; Codemode-style intermediation offers concrete solutions.
- Teams using multiple MCP servers can evaluate moving tool definitions out of prompts and setting exposure levels by tool sensitivity to reduce misuse risk.
