Toolcall MCP

30 pay-per-call APIs for AI agents, over MCP. Compliance, trade, safety, web, and data tools an agent can call directly. No account, no API key. Each call costs a few cents in USDC on Base via the x402 protocol, and the calling client pays automatically when it supports x402.

Remote MCP endpoint: https://toolcall.click/mcp (Streamable HTTP)
Catalog / manifest: https://toolcall.click/ and https://toolcall.click/.well-known/x402
OpenAPI: https://toolcall.click/openapi.json

What you get

One MCP server, 30 tools spanning things agents actually need but that are annoying to wire up: official sanctions/AML screening, HS-code customs classification, chemical safety, FDA drug/device intelligence, electronic-component pricing, SEC financials, and clean web tooling (search, reader, screenshot, tech-stack, archive history). Every tool is a single call that aggregates authoritative sources and returns clean JSON.

Connect

Any MCP client that supports remote Streamable HTTP servers

Point it at:

https://toolcall.click/mcp

Claude Desktop / Cursor / stdio-only clients

Bridge the remote server to stdio with mcp-remote:

{
  "mcpServers": {
    "toolcall": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://toolcall.click/mcp"]
    }
  }
}

Paying for calls

Tools are priced per call (see table). The payment model is client-pays: calling a tool without payment returns the exact price and x402 payment requirements in the result's _meta["x402/payment-required"] field. An x402-capable client signs a USDC payment on Base (gasless, EIP-3009) and retries with the signed payload in params._meta["x402/payment"]. The server never holds or forwards funds — payment goes straight to the tool operator's wallet.

You can also call any tool over plain HTTP with a standard x402 client (e.g. x402-fetch, x402-axios, or the Coinbase CDP Bazaar): a bare request returns HTTP 402 with payment requirements; pay and retry the same URL.
