Free Agent Tools

Sixteen small, deterministic tools your AI agent can call: score a business idea, check price headroom, work out hotel OTA commission, find open-source swaps for SaaS bills, read a Google or Meta ads notice, precheck an iOS app for App Store 4.2, reality-check an AI YouTube plan, explain AI infrastructure bottlenecks, and plan a Japan trip by city and month.

Add this URL to any MCP client that supports streamable HTTP:

https://free-agent-tools.vercel.app/mcp

No API key, no account, no tracking of tool inputs. Results are rules of thumb and educational estimates, not financial, legal, or investment advice; every result carries a disclaimer for the user.
