Agent402 MCP — agent-tools.cloud

Hosted MCP connector for the Agent402 server (~1,100 deterministic web tools). Four meta-tools — `search_tools`, `find_tool`, `call_tool`, `about_agent402` — let an agent discover and invoke the full catalog without bloating its tool list. Dual-rail payment: free via proof-of-work for pure-CPU tools, paid via x402 USDC on Base/Polygon/Arbitrum for the rest. No LLM in the serving path. Categories: browser, search, PDF/image/OCR/audio, geo, live data (FX, weather, USGS, gov-data), network truth (DNS/TLS/WHOIS), crypto/x402 helpers, ~1,040 pure-CPU utilities. Self-hostable; also distributed as the [`agent402-mcp`](https://www.npmjs.com/package/agent402-mcp) stdio package and registered with the official MCP Registry as `io.github.MikeyPetrillo/agent402`.

Paid verification

How it works

No sponsored paid call yet.

Pay this endpoint once from your own wallet (Base USDC, up to $1.00) and we call it and record what came back. Your wallet pays the listed recipient directly; Agent Tools never holds funds. Sponsored checks prove delivery; they do not count as demand.
