Cofferdock for AI assistants
Connect Cofferdock to your assistant and just ask: "make an Instagram card with these prices", "merge these PDFs and number the pages", "take a screenshot of this site". The assistant writes the design, calls the tool and hands you the file.
What you need
- A free account: sign up here.
- The MCP server address:
https://api.cofferdock.com/mcp - With Claude on the web or mobile you need nothing else: you connect by signing in with your account, no key to copy. For everything else (Claude Code, Cursor, n8n…) use an API key: copy it from your dashboard.
Each successful call uses 1 credit from your plan, same as from n8n or Make. Files come back as a download link that lasts 15 minutes.
Claude (web and mobile)
- In Claude, go to Customize → Connectors → Add custom connector.
- Enter the address
https://api.cofferdock.com/mcp. - If it asks how to authenticate, choose Sign in now and, as the OAuth client, Register automatically.
- Click Add and then Connect: Cofferdock opens, you sign in and press Allow.
- In a conversation, turn Cofferdock on from the + → Connectors and ask for whatever you need.
To disconnect, delete the "Claude (OAuth)" key in your dashboard or remove the connector in Claude. Each connection renews itself and can only use your credits.
Claude Code
In your terminal:
claude mcp add --transport http cofferdock https://api.cofferdock.com/mcp --header "x-api-key: YOUR_KEY"Cursor
In ~/.cursor/mcp.json (or .cursor/mcp.json in your project):
{
"mcpServers": {
"cofferdock": {
"url": "https://api.cofferdock.com/mcp",
"headers": { "x-api-key": "YOUR_KEY" }
}
}
}VS Code (GitHub Copilot)
In .vscode/mcp.json:
{
"servers": {
"cofferdock": {
"type": "http",
"url": "https://api.cofferdock.com/mcp",
"headers": { "x-api-key": "YOUR_KEY" }
}
}
}Claude Desktop
Claude Desktop connects to remote servers through the mcp-remote bridge (requires Node.js). In Settings → Developer → Edit config:
{
"mcpServers": {
"cofferdock": {
"command": "npx",
"args": ["mcp-remote", "https://api.cofferdock.com/mcp", "--header", "x-api-key:${COFFERDOCK_KEY}"],
"env": { "COFFERDOCK_KEY": "YOUR_KEY" }
}
}
}n8n (AI agents)
Inside an AI Agent node, add the MCP Client Tool: set the address to https://api.cofferdock.com/mcp, the transport to HTTP Streamable, and header authentication with the name x-api-key and your key as the value.
ChatGPT
The simplest way today is a GPT with "Actions" that uses the Cofferdock API (OpenAPI description, API key authentication in the x-api-key header). A direct MCP connection from ChatGPT (with sign-in) is being tested; for now, use the GPT with Actions.
