Builder Prime MCP by usefulapi

Hosted endpoint: https://builder-prime.usefulapi.io/mcp

Connect

• Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://builder-prime.usefulapi.io/mcp.
• Claude Code: claude mcp add --transport http builder-prime https://builder-prime.usefulapi.io/mcp, then run /mcp to log in.
• VS Code: Add to VS Code.
• Cursor and other clients: add the URL as a remote MCP server:

{
  "mcpServers": {
    "builder-prime": {
      "url": "https://builder-prime.usefulapi.io/mcp"
    }
  }
}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Builder Prime credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/builder-prime/

Verification limitation: real-account authentication, reads and writes have not been tested. Published example-tenant probes return a generic JSON 400 for missing and synthetic keys. This release passed mock integration and hosted Worker tests; real-tenant verification remains outstanding.
