The Caranguejo MCP server
Connect by URL — no download, no npx, no config file. Paste it into Claude and generate images, videos and edits with your account and credits.
Connect in three steps
No API key, no install — just a URL.
Copy the URL
This is the hosted Caranguejo MCP endpoint — the same one for every client.
https://mcp.caranguejo.art/mcpAdd the connector
In Claude, open Settings → Connectors, add a custom connector named “Caranguejo” and paste the URL. (Cursor: Settings → MCP → Add — same URL.)
Open connectors in ClaudeConnect and sign in
Click Connect and log into your Caranguejo account (OAuth) — that's it. Just ask the agent to generate.
What your agent can do
Everything the app does, your agent does too.
Generate image and video up to 4K
Every model in the catalog, including 4K-resolution output.
Edit and compose images
Edit, restyle and compose existing images, straight from chat.
Post-production and upscale
Upscale, background removal, relight, inpaint and other finishing tools.
Generation history
List and resume past generations — the agent sees what you've already created.
Every model, live
The full, always-current catalog the agent can dispatch — image, video, audio and tools.

Advanced: headless agents
Claude Code, terminal agents and other clients without a connectors UI use the URL with an auth header — or the legacy local package.

Authorization: Bearer ck_live_xxxxxxxxCommon questions
Do I need an API key?
No — to use it from Claude, just connect the URL and sign in to your account. A ck_live_ key is only needed for the advanced/headless mode (Claude Code, terminal agents).
Which clients work?
Claude on the web and in Claude Code, Cursor, and any client that supports MCP over Streamable HTTP.
How is it billed?
It uses your Caranguejo plan's credits, same as the app — every generation returns its cost in credits_charged.
How long does a generation take?
It's asynchronous — the agent waits for the result. Images finish in seconds; video can take a few minutes.
Can I reuse past generations?
Yes — list_generations returns your history, so the agent can reference or reuse media you already created.
