# 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](https://base.org) via the [x402](https://x402.org) 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`](https://www.npmjs.com/package/mcp-remote):
```json
{
"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.
