Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on your computer with your user’s permissions (files, network, apps).
You fill in yourself: CLAWFETCH_PRIVATE_KEY

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "clawfetch": {
      "command": "npx",
      "args": [
        "-y",
        "@clawfetch/mcp"
      ],
      "env": {
        "CLAWFETCH_PRIVATE_KEY": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add clawfetch --env CLAWFETCH_PRIVATE_KEY=your-value -- npx -y @clawfetch/mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "clawfetch": {
      "command": "npx",
      "args": [
        "-y",
        "@clawfetch/mcp"
      ],
      "env": {
        "CLAWFETCH_PRIVATE_KEY": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "clawfetch": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@clawfetch/mcp"
      ],
      "env": {
        "CLAWFETCH_PRIVATE_KEY": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

CLAWFETCH_PRIVATE_KEY secret required env
EVM private key for a Base wallet holding USDC (pays x402 micropayments gaslessly)

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

Common questions

Is Clawfetch MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: CLAWFETCH_PRIVATE_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.4.0) reached the registry 16 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

@clawfetch/mcp

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.

Access and payment

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.

💻 Self-Hosted Mode

Run your own instance with full control over the payment wallet.

Install

npm install -g @clawfetch/mcp

Configure (stdio — for local MCP clients)

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.

Run as HTTP Server

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.

HTTP Endpoints

Endpoint	Method	Description
`/mcp`	POST	Initialize session — returns `Mcp-Session-Id` header
`/mcp`	GET	SSE stream for server-to-client notifications (requires session ID)
`/mcp`	DELETE	Close a session
`/health`	GET	Server health check (JSON)

Session Flow

Initialize: POST /mcp with JSON-RPC initialize request → get Mcp-Session-Id header
Call tools: POST /mcp with Mcp-Session-Id header + JSON-RPC tools/call request
Stream: GET /mcp?sessionId=... for SSE notifications (optional)
Close: DELETE /mcp with Mcp-Session-Id header

Environment Variables

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.
