Install GCP Platform Engineer in Cursor

What you need first

• Cursor, installed.
• uv, which gives the uvx command the server starts with.

Steps

1. Open ~/.cursor/mcp.json, or create it. For one project only, use .cursor/mcp.json in that project.
2. Add this block. If the file already has mcpServers, add only the entry inside it.

{
  "mcpServers": {
    "platform-mcp": {
      "command": "uvx",
      "args": ["platform-mcp==0.4.0"]
    }
  }
}

3. Save the file. In Cursor's settings, find the server in the MCP section and turn it on if it is off.

Check it worked

Ask Cursor: List the tools of platform-mcp.

If it does not start

spawn uvx ENOENT

uv is not on the PATH that Cursor sees. Install it, or write the full path of uvx in the config.

Nothing changes after a restart

The file is not valid JSON any more. Look for a missing comma where the block was added.
