Returns per-request and monthly cost with sources. ``` ### `run_tool` - The name "run_tool" says "run": a word for a change. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text Run one of our free tools. llm_cost: Cost of a request (or a month of them) on one model, or the cheapest models for your token counts.
