I Was Going to Ship 155 MCP Tools. The Token Math Said 10.
Difficult_Coffee_713 · reddit · 2026-09-26
A developer measured before shipping: 155 one-per-endpoint MCP tools would burn 128K tokens per turn and cause wrong tool picks among near-identical names. They compressed to 10 task-shaped tools plus listroutes/callroute fallbacks, requiring unified response schemas (12 spellings of follower count), readonlyhint, output schemas, and parameter-level docs. Smithery score jumped from 60 to 82.
