Web intelligence for AI agents: fetch, render, extract, research. x402 micropayments, no API keys.
MCP (Model Context Protocol) server for ClawFetch — Web Intelligence API for AI Agents.
Gives any MCP-compatible client (Claude Desktop, Cursor, Windsurf, OpenClaw, etc.) instant access to ClawFetch's web intelligence tools: fetch pages as markdown, render JS-heavy SPAs, extract structured data from 17+ site types, research topics multi-source, and check domain availability.
Payments are handled automatically via the x402 protocol — USDC on Base. No API keys, no billing dashboards.
Connect directly to the hosted MCP server — no installation required:
Endpoint: https://mcp.clawfetch.ai/mcp
Add to claude_desktop_config.json:
{
"mcpServers": {
"clawfetch": {
"type": "url",
"url": "https://mcp.clawfetch.ai/mcp"
}
}
}
Add to your MCP configuration:
{
"mcpServers": {
"clawfetch": {
"url": "https://mcp.clawfetch.ai/mcp"
}
}
}
mcp:
servers:
clawfetch:
url: https://mcp.clawfetch.ai/mcp
Note: The hosted server handles x402 payments server-side. Tools that require payment (fetch, render, extract, research) will charge USDC on Base per call. Free tools (health_check, wallet_info, list_extractors) work without payment.
Run your own instance with full control over the payment wallet.
npm install -g @clawfetch/mcp
Add to your MCP client config (e.g., Claude Desktop):
{
"mcpServers": {
"clawfetch": {
"command": "clawfetch-mcp",
"env": {
"CLAWFETCH_PRIVATE_KEY": "0xYOUR_ETHEREUM_PRIVATE_KEY"
}
}
}
}
The private key signs x402 micropayments (USDC on Base). Fund the corresponding address with USDC on Base mainnet.
Expose the MCP server over HTTP for remote clients:
CLAWFETCH_PRIVATE_KEY=0x... CLAWFETCH_TRANSPORT=http CLAWFETCH_PORT=3001 clawfetch-mcp
This starts a server at http://localhost:3001/mcp using the Streamable HTTP transport (MCP spec compliant).
