Web intelligence for AI agents: fetch, render, extract, research. x402 micropayments, no API keys.
这三项永远不会合并成一个分数:意见、测量和人气是不同的东西。
我们还没有为它写通俗的介绍。下面是我们从注册中心读取到的事实。
选择你使用的 AI 应用,然后复制设置。
CLAWFETCH_PRIVATE_KEY标为机密的值是你账户的钥匙。千万不要分享给别人,也不要粘贴到聊天里。

在上方选择你的应用。我们会记住它,下次按钮会显示“安装到 …”。
打开 Claude Desktop → Settings → Developer → Edit Config,把下面的内容粘贴到 claude_desktop_config.json
{
"mcpServers": {
"clawfetch": {
"command": "npx",
"args": [
"-y",
"@clawfetch/mcp"
],
"env": {
"CLAWFETCH_PRIVATE_KEY": "your-value"
}
}
}
}在终端中运行这条命令
claude mcp add clawfetch --env CLAWFETCH_PRIVATE_KEY=your-value -- npx -y @clawfetch/mcp运行前请先填写空着的值。

"args": [
"-y",
"@clawfetch/mcp"
],
"env": {
"CLAWFETCH_PRIVATE_KEY": "your-value"
}
}
}
}浏览器会先询问是否打开应用,然后应用会显示设置并请你确认。密钥的值会留空,由你自己填写。

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, enrich companies from a domain, and check domain availability.
Payments are handled automatically via the x402 protocol — USDC on Base. No API keys, no billing dashboards.
The public hosted MCP endpoint is retired and returns HTTP 410 Gone. Run the MCP locally using the setup below, or call https://api.clawfetch.ai directly. Paid tool calls use your own USDC-funded wallet on Base; ClawFetch does not subsidize requests.
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). By default it binds to 127.0.0.1 and accepts only loopback Host headers, which blocks DNS-rebinding attacks from web pages. To serve remote clients, set CLAWFETCH_HOST=0.0.0.0 and list your public hostnames in CLAWFETCH_ALLOWED_HOSTS.

| Variable | Required | Default | Description |
|---|---|---|---|
CLAWFETCH_PRIVATE_KEY | Yes* | — | Ethereum private key (0x-prefixed) for x402 payments |
CLAWFETCH_BASE_URL | No | https://api.clawfetch.ai | API base URL |
CLAWFETCH_TRANSPORT | No | stdio | Transport: stdio or http |
CLAWFETCH_HOST | No | 127.0.0.1 | HTTP server bind address |
CLAWFETCH_ALLOWED_HOSTS | No | localhost,127.0.0.1,[::1] | Comma-separated Host header allowlist for the HTTP transport (DNS-rebinding protection) |
CLAWFETCH_PORT | No | 3001 | HTTP server port |
CLAWFETCH_TIMEOUT_MS | No | 60000 | Request timeout in ms |
CLAWFETCH_DEBUG | No | false | Enable debug logging (1 or true) |
\* Required for tool calls. Without it the server still starts and lists its tools, resources and prompts (so registries can inspect it), and every call returns setup instructions. Keep this key in your local configuration; never submit it to the ClawFetch website.
