Overview

AI-generated overview

ClawPage is a local MCP server that turns any web page into clean structured JSON, with a free daily quota and paid USDC options.

What you can do
Extract any URL into structured JSON covering text, tables, prices, contacts, hours, ratings, dates, links and images, with cache hits free for 24 hours. Create an account and obtain an API key with a free daily extraction quota. Check remaining free extractions and prepaid USDC balance. Associate a wallet address and credit the balance from an on-chain USDC transfer.
When to use it
Useful when an assistant needs to pull structured facts from arbitrary web pages, such as prices, contact details, opening hours or tables, rather than raw HTML. Suited to occasional extraction within the free daily quota or to paid high-volume use.
Requirements
Runs locally via npx (Node.js) over stdio, or with the --http flag on port 8080 (override with MCP_PORT). Needs network access to the ClawPage API. An API key from the register tool is recommended; prepaid USDC on Base or anonymous x402 on-chain payment are alternatives.
Before you install
Registration requires an email address, and the API key (cpk_ prefix) is a credential to keep private. Paid use involves USDC deposits and on-chain wallet addresses, so real funds are at stake; extraction costs $0.01 each beyond the free tier. Page content is sent to the third-party ClawPage API.

Installation

In SourceWeft

  1. Open ClawPage in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.
