Overview

AI-generated overview

ExtractEdge is a remote MCP server that turns any web page into clean, LLM-ready markdown, with a free capped demo and paid per-extraction use.

What you can do
Fetch a web page by URL and convert it to markdown or plain text, with main-content detection that drops navigation, footers and ads, and metadata such as title, description, final URL, status code and links returned alongside. Run extractions in a free demo mode that returns a capped amount of the page, or in a paid mode that returns the full markdown plus a payment receipt.
When to use it
Useful when an assistant needs readable page content for summarization, research or ingestion and you want a hosted converter without signup or an API key. The free demo suits occasional small pages; the paid lane suits larger or unlimited extraction volume.
Requirements
A remote streamable HTTP endpoint; no local runtime, account or API key is needed. The free demo is rate-limited per IP. Paid extraction requires an x402 payment of 0.001 USDC on Base mainnet, signed from a crypto wallet.
Before you install
Paid extraction spends real USDC on Base mainnet and requires signing a payment authorization with a wallet, so treat wallet keys as sensitive. The service fetches arbitrary URLs on your behalf, and page content and URLs are sent to a third-party Cloudflare Worker. The paid lane is described as unlimited with abuse control only on the demo lane.

Installation

In SourceWeft

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

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.vasilicasijarvis%2Fextractedge/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

README

ExtractEdge

Firecrawl-lite: turn any web page into clean LLM-ready markdown. Fast, cheap, crypto-native. Live: https://extractedge.lastunmihai1986.workers.dev

Why

Firecrawl starts at $16/mo for ~1k credits and requires signup + API key. ExtractEdge is $0.001/extract pay-per-use over x402 (USDC on Base mainnet), no signup, no API key — designed for AI agents.

Quick start (free demo)

bash
curl -X POST "https://extractedge.lastunmihai1986.workers.dev/extract?demo=1" \  -H "content-type: application/json" \  -d '{"url":"https://example.com"}'

Free demo returns up to 3,000 chars of the page as markdown. No payment needed.

Paid extraction (x402, USDC on Base)

  1. POST /extract {"url":"https://target.page"} → 402 with PAYMENT-REQUIRED header (base64 JSON)
  2. Sign an EIP-3009 transferWithAuthorization for 1000 atomic units (0.001 USDC) on Base
    • asset: 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 (USDC)
    • payTo: 0xa1b8be63bde77ddc65d9ffe8a21a2a5f2c9ca6a8
  3. Retry with the PAYMENT-SIGNATURE header (base64 PaymentPayload JSON) → 200 with full markdown + PAYMENT-RESPONSE receipt

Python client example: see scripts/e2e_paid2.py (eth_account EIP-712 signing, ~40 lines).

Architecture

Single Cloudflare Worker (stdlib-only, zero npm deps):

  • src/index.js — router + info endpoints
  • src/extract.js — fetch pipeline (timeout, redirects, content-type dispatch)
  • src/md.js — HTMLRewriter → DOM tree → markdown/text + main-content scoring
  • src/x402.js — x402 v2 gate: 402/PAYMENT-REQUIRED, EIP-3009 verify+settle via Coinbase CDP facilitator (Ed25519 JWT per request), Bazaar discovery declaration
  • src/mcp.js — MCP Streamable HTTP server (JSON-RPC 2.0)
