ToolFit by YourAITools
AI agent tool change detector API (MCP tool diff). Compare an agent tool list now (tools array or public remote MCP URL) with a pin from an earlier ToolFit call (or a baseline array): removed or added tools, changed descriptions with a word diff and new poisoning findings, removed or newly required params, type and enum changes, annotation changes. Verdict: unchanged, compatible, review, suspicious or breaking.
