Connect Cursor to Enrichr

Reverse-engineer any website — design system, animations, WebGL/shaders, 3D scene graph, recovered source — directly from Cursor's Agent chat. Two minutes, no code.

1Get an API key

Keys look like enrichr_7f3a9c2e1b8d4a6f…. Sign in and create one from your account page — it's shown once, so copy it right away.

Go to your account →

2Add the MCP server

Cursor reads MCP servers from mcp.json. Create .cursor/mcp.json in your project (or ~/.cursor/mcp.json for every project) with:

{
  "mcpServers": {
    "enrichr": {
      "url": "https://enrichr.dev/mcp",
      "headers": {
        "X-API-Key": "enrichr_your-key-here"
      }
    }
  }
}

Or skip the file: open Cursor Settings → MCP → Add new MCP server and paste the same URL and header.

Cursor lists Enrichr's tools under Available Tools once the server connects — no restart needed for a remote server like this one.

Raw HTTP (any client)

# List every tool
curl -X POST https://enrichr.dev/mcp/tools \
  -H "X-API-Key: enrichr_your-key-here"

# Call one
curl -X POST https://enrichr.dev/mcp/invoke \
  -H "Content-Type: application/json" \
  -H "X-API-Key: enrichr_your-key-here" \
  -d '{"tool":"rebuild_brief","arguments":{"url":"https://bruno-arizio.fr"}}'

3Use it

Ask Cursor's Agent in plain language:

Give me a rebuild brief for https://bruno-arizio.fr
Extract the design system from https://gsap.com
What's in the 3D scene on https://threejs.org/examples/webgl_animation_keyframes.html
Recover the original source for https://myoldsite.com

Cursor will ask to approve each tool call the first time — the same approval flow as any other MCP tool.

The tools

Start here

Tool	What you get	Credits
`rebuild_brief`	One document written for an LLM to rebuild the site from: tokens, components, exact animation timings, shader GLSL, scene graph, fonts, assets, recovered source — plus a full capture zip	5
`extract_site_profile`	Everything above as structured JSON	3

Multi-page — everything above runs against one page. For more than one:

Tool	What you get	Credits
`map_site`	Every URL a site declares (sitemap/robots, falling back to same-origin links) — discovery only	1
`crawl_site`	Discovery, then a real capture of up to `max_pages` of them	1

Focused extraction

Tool	What you get	Credits
`extract_design_system`	CSS variables, palette, type scale, spacing, easings, breakpoints, webfonts	1
`extract_source_maps`	Original TypeScript/JSX recovered from shipped bundles	2
`extract_scene_graph`	Three.js meshes, materials, textures, lights, camera, renderer config	1
`reverse_engineer_animations`	GSAP tweens, ScrollTriggers, Framer Motion, Lenis	1
`reverse_engineer_webgl`	Canvas info, compiled GLSL, 3D model URLs, draw-call stats	1
`reverse_engineer_dom`	Full DOM tree, headings, landmarks, tables, forms, link inventory	1
`reverse_engineer_assets`	Every asset with real sizes and MIME types	1

Plus scraping, OCR, screenshot, and analysis tools — POST /mcp/tools lists all of them.

Troubleshooting

Problem	Fix
`Missing X-API-Key header`	Add the auth header to your `mcp.json` entry
`Invalid API key`	Keys start with `enrichr_`. Check for a trailing space
`This API key has been revoked`	Issue a new one from the dashboard
`Monthly credit limit reached`	The error names your plan and usage; upgrade or wait for the reset
No tools show up under Available Tools	Check the server shows a green dot in Cursor Settings → MCP; the endpoint is `/mcp`, not the bare domain
Request timeout	Heavy WebGL sites can take 30-60s. Retry, or use a focused tool

FAQ

Is my data stored?
Extraction results are not persisted. We record which tool you called, when, and the URL — that is what meters your credits. Page content is not retained.

Can I share my key?
No. Credits are per-account; sharing shares your quota. Issue a second key from the dashboard instead — you can revoke it independently.

Why did an extraction cost more than I expected?
Cost is per tool, not per page. rebuild_brief holds a browser for far longer than a token read, so it costs 5. The table above lists every price.
