Free Agent Tools: free remote MCP server

A free, no-auth remote MCP server (streamable HTTP) with 16 small, deterministic tools your AI agent can call: business idea scoring, price headroom, hotel OTA commission, open-source swaps for SaaS bills, Google Ads / Meta Ads notice risk, App Store 4.2 / 4.3 precheck, faceless YouTube reality check, AI infrastructure bottlenecks, viral attention patterns, and Japan trip planning.

Endpoint: https://free-agent-tools.vercel.app/mcp
Landing page with setup for every client: https://free-agent-tools.vercel.app

No API key, no account, nothing to install. Results are rules of thumb and educational estimates, not financial, legal, or investment advice, and every result carries a disclaimer for the user.
