AI orchestrator cuts token waste by enforcing tool contracts

A content operations orchestrator, designed to manage tasks like planning, drafting, and scheduling posts, experienced significant token usage and errors due to its interaction with an MCP server. Analysis revealed that only three out of eleven available tools were responsible for 91% of the API calls, leading to substantial token overhead from sending unused tool schemas with every request. The system also encountered argument validation errors, often stemming from the model confusing similar tools like 'publish_draft' and 'schedule_post'. To address these issues, the author implemented a new requirement: all 'write' tools must have a documented 'undo' tool, which immediately eliminated tools like 'archive_draft' that lacked a clear inverse operation accessible to the agent.

    11 tools in my MCP server, 3 of them did 91% of the calls: what I ask before adding a 12th

    <p>Two weeks ago the MCP server behind my orchestrator exposed 11 tools. It exposes 4 now. Nothing the agent does changed, because three of those 11 were already doing 91% of the work and I had never bothered to count.</p> <p>The orchestrator is a small thing I run for content op…
