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 claude_desktop_config.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
| Tool | What it does |
|---|---|
extract | Synchronous extraction from a single URL (up to ~90s). Returns { data, meta }. |
extract_async | Submit an async job for heavy or anti-bot pages. Returns a job id immediately. |
get_job | Poll an async job for status and result. |
list_jobs | List your recent async jobs. |
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:
| Variable | Required | Description |
|---|---|---|
EXTRACTO_API_KEY | yes | Your key from app.getextracto.dev/keys. |
EXTRACTO_BASE_URL | no | Override the API host (defaults to https://app.getextracto.dev). |
EXTRACTO_TIMEOUT_MS | no | Per-request timeout in ms (default 90000). |
