Extracto tools (4, 1 write)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • extract

    Extract structured data from a public web page and return it as validated, typed JSON. Extracto renders the page (JavaScript included), runs a schema-constrained extraction, and returns ONLY fields that match the schema. Missing data comes back as null rather than a hallucinated guess. Best for a single known URL. This call is synchronous (up to ~90s); for heavy or anti-bot pages prefer `extract_a

  • extract_asyncwrite action

    Submit an asynchronous extraction job for a heavy, slow, or anti-bot-protected page. Returns a job id immediately; poll it with `get_job` until status is "success" or "failed". Use this instead of `extract` when a page is large or likely to need stealth rendering.

  • get_job

    Fetch the current status and (once complete) the result of an async extraction job created with `extract_async`. Status is one of pending, processing, success, failed.

  • list_jobs

    List your recent async extraction jobs, newest first.

Install Extracto in Claude Code, Cursor or VS Code

Runs npx -y extracto-mcp on your machine. Read the scan report first; the gateway never runs local packages.

claude mcp add extracto-mcp -- npx -y extracto-mcp
Add to Cursor

What the publisher says

From the Extracto repository's README, as published. We do not edit it. Read it on GitHub

extracto-mcp

Model Context Protocol server for Extracto. It gives Claude, Cursor, Claude Code, and any MCP client the ability to turn a URL plus a schema into validated, typed JSON — no prompt engineering, no HTML parsing, and no hallucinated fields (missing data comes back as null).

Quick start

You need an Extracto API key. Get one at app.getextracto.dev/keys.

The server runs over stdio and is published to npm, so most clients just need this config block.

Claude Desktop

Edit claudedesktopconfig.json (Settings → Developer → Edit Config):

{
  "mcpServers": {
    "extracto": {
      "command": "npx",
      "args": ["-y", "extracto-mcp"],
      "env": { "EXTRACTO_API_KEY": "exa_live_your_key_here" }
    }
  }
}

Cursor

Add to ~/.cursor/mcp.json (or the project .cursor/mcp.json) with the same block.

Claude Code

claude mcp add extracto -e EXTRACTO_API_KEY=exa_live_your_key_here -- npx -y extracto-mcp

Restart the client and ask it to extract something, e.g. "Use extracto to pull the title, language and star count from github.com/facebook/react."

Tools

The schema argument

A schema is an object mapping field names to types. A type is:

  • a literal: "string", "number", "boolean", "array", "object"
  • a one-element array for a list: ["string"], or [{ "title": "string" }]
  • a nested object: { "author": { "name": "string" } }
{
  "title": "string",
  "price": "number",
  "tags": ["string"],
  "reviews": [{ "user": "string", "stars": "number" }]
}

Only fields that are actually found on the page are returned; anything missing is null rather than guessed.

Configuration

All configuration is via environment variables passed by your MCP client:

Development

npm install
npm run dev        # run from source with tsx
npm run typecheck
npm run build      # bundle to dist/ with tsup
