Connect Claude to Prometheux

Connect Claude (Desktop or Web) to Prometheux using the Remote MCP Server. This guide covers the Claude-specific setup steps — for local installation with Claude Desktop, see the Local MCP Server page instead.

Prerequisites​

  • Claude account (Desktop or Web) at claude.ai

Setup​

  1. Open Claude (Web at claude.ai, or Desktop app)

  2. Add the MCP Server:

    • Click your profile icon → Settings
    • Navigate to "Connectors"
    • Click "Add custom connector"

  3. Configure the connection:

    • Name: prometheux (or any name you prefer)
    • Remote MCP Server URL: https://api.prometheux.ai/px-remote-mcp-server
    • Click "Add"

  4. Connect:

    • Click "Connect" on the Prometheux connector

    • Enter your credentials:
      • Username: Your Prometheux username
      • Organization: Your Prometheux organization
      • API Token: Your Prometheux authentication token
    • Click "Connect to Claude"

  5. Start using: The connection is now active. Claude will automatically use the Prometheux tools when relevant to your queries.

Troubleshooting​

"Unable to connect" error​

OAuth login page doesn't load​

Solution:

Tools not appearing in Claude​

Solution:

  • Ensure you completed the OAuth flow successfully
  • Check Claude's developer console (F12) for error messages
  • Try disconnecting and reconnecting the server
  • Verify the connector shows as "Connected" in Settings
  • Be more explicit in your query: "Use the prometheux tools to list concepts in project X"
