Connect / Cursor

Connect OntoRamp to Cursor

Add OntoRamp to Cursor via mcp.json or one-click install.

Works on all Cursor plans.

Before you start

You need an OntoRamp API key — get one free at ontoramp.com/mcp. Keys arrive by email within 60 seconds and are passed as a Bearer token in the Authorization header: Authorization: Bearer YOUR_API_KEY. If your tool asks for an API key directly, paste just the key — the header is added for you.

Server URLs

Setup

Each server in the table above is its own connection — repeat the setup (or add another config entry) for each one you want.

1. 1.Create or open .cursor/mcp.json in your project (or ~/.cursor/mcp.json to apply to all projects).
2. 2.Add the OntoRamp server using the snippet below, replace YOUR_API_KEY, and save — or use a one-click install link below, then replace YOUR_API_KEY in the generated entry.
3. 3.Open Cursor Settings (Ctrl/Cmd+Shift+J) → the MCP section (currently labeled Tools & MCP) and confirm the server is on and its tools are listed.
4. 4.If the connection fails, open the Output panel (Ctrl/Cmd+Shift+U) and select MCP Logs.
