Search Agent402's 1123 pay-per-call web tools (encoding, crypto, text, time, math, validation, unit conversions, network, browser, PDF, search, memory). 1076 pure-CPU tools run free right here; the rest need a USDC wallet. Returns slugs + input schemas for call_tool.

Describe a task in plain language and get the best-matching Agent402 tool(s) ready to call — slug, price, input schema, and an example — so you skip searching/exploring. Then run call_tool with the chosen slug + params.

Run an Agent402 tool by slug (find slugs with search_tools). The 1076 pure-CPU tools execute free on this hosted connector (rate-limited). Wallet-only tools (live search, browser rendering, PDFs, durable memory) return instructions for paid access instead.

What this connector is: the free tier of agent402.tools, what's free vs wallet-only, and how paid access works (x402, USDC on Base, proof-of-work).

概要

What is Agent402?

Agent402 is an open-source, self-hostable MCP server that provides an index over the x402 ecosystem (Find, Route, Leaderboard) plus a catalog of ~1,100 deterministic tools for AI agents. It gives developers a single integration for discovering, routing, and calling tools across multiple sellers, with no LLM in the serving path.

How to use Agent402?

You can use Agent402 by adding its hosted connector to Claude (claude.ai → Settings → Connectors → Add custom connector with URL https://agent402.tools/mcp), or by running the MCP server locally with npx -y agent402-mcp, or by cloning the repository and starting it with FREE_MODE=true npm start. A one-click deploy to Railway is also available.

FAQ from Agent402

What makes Agent402 different?

Agent402 is open-source and self-hostable, and a single integration gives three free primitives over the whole x402 ecosystem: Find (task-to-tool routing), Route (Smart Order Router across sellers), and Leaderboard (on-chain seller ranking). It also includes ~1,100 deterministic tools.

Do I need an API key or signup to use Agent402?

No. By default everything runs free; no wallet is required in free mode. You can self-host without any API keys.

Can I charge for tool calls?

Yes, optionally. The server can charge per call over the x402 protocol (USDC on Base). That part is opt-in; by default everything runs free.

What framework adapters are available?

Agent402 provides drop-in packages for OpenAI, Anthropic, Vercel AI SDK, LangChain, LlamaIndex, and Strands. These turn the catalog into native tool objects with payment handled underneath.

How does the Router work?

The Smart Order Router (POST /api/route) ranks tools across sellers by match score, then health, then price. Sellers whose last few crawls errored are excluded; new sellers get the benefit of the doubt. The leaderboard is an on-chain snapshot of settled USDC volume.
