I have been building an agentic system on a custom internal platform and the llm keeps calling tools with identifiers that dont exist, wrong namespace, wrong handle, wrong enum. gets back an error, retries, still wrong. every bad call is tokens down the drain. I ended up writing a big system prompt to fix it. took weeks of trial and error. its working but i still dont fully trust it. I am curious if others are hitting this or if its just me. Especially if youre running MCP servers on internal platforms the llm has never seen before(the problem occurs most with less powerful models), do you guys have a go to solution for this? Thanks
