Remote MCP Server

The remote MCP server (px-remote-mcp-server) is a cloud-hosted Model Context Protocol server that enables any MCP-compatible AI agent to interact with Prometheux — without needing to install anything locally. It uses OAuth 2.0 authentication with PKCE, so users log in through a browser and their credentials are never exposed to the AI client.

Why Use Remote MCP?

Best for: Multi-client integrations, enterprise environments, browser-based AI agents Pros:
  • Works with any MCP-compatible client (Claude, Genie Code, and more)
  • OAuth 2.0 authentication with browser login flow
  • Centralized deployment (one server, many users)
  • Handles authentication and session management
  • No local installation required
Cons:
  • Requires a deployed server instance
  • Suitable for production cloud deployments
If you prefer a local installation that doesn’t require a deployed server, check out the Local MCP Server documentation.

Authentication Flow

When connecting through any MCP client, the OAuth flow works as follows:
  1. The client redirects you to the Prometheux login page
  2. You enter your credentials:
    • Username: Your Prometheux username
    • Organization: Your Prometheux organization
    • API Token: Your Prometheux authentication token
  3. After successful authentication, the client receives a session token
  4. All subsequent MCP requests use this token automatically

For other MCP-compatible clients, use the Server Details and OAuth Endpoints above to configure the connection manually.

Session Management

  • Sessions persist until you explicitly disconnect or the server restarts
  • Re-authentication: If your session expires, the client will prompt you to log in again
  • Security: Your Prometheux token remains valid until you revoke it from your Prometheux dashboard

Troubleshooting

”Unable to connect” error

The client can’t reach the remote MCP server. Solution:
  • Verify the server URL is correct: https://api.prometheux.ai/px-remote-mcp-server
  • Check if your Prometheux credentials are valid
  • Ensure the remote MCP server is running and accessible
  • Try refreshing and reconnecting

OAuth login page doesn’t load

The authentication flow isn’t starting properly. Solution:
  • Check your browser’s popup blocker settings
  • Try the connection flow in an incognito/private window
  • Verify the remote MCP server is running and accessible
  • Clear your browser cache and cookies

”Authentication required” after login

Your session expired or credentials are invalid. Solution:
  • Your Prometheux token may have been revoked or expired
  • Re-authenticate by disconnecting and reconnecting
  • Contact your Prometheux admin to verify your credentials
  • Check that you entered the correct username, organization, and token

Tools not appearing

The AI agent doesn’t recognize the Prometheux tools. Solution:
  • Ensure you completed the OAuth flow successfully
  • Try disconnecting and reconnecting the server
  • Verify the connection shows as active in your client’s settings
  • Be more explicit in your query: “Use the prometheux tools to list concepts in project X"

"Connection timeout” error

The remote MCP server is taking too long to respond. Solution:
  • Check your internet connection
  • Verify the Prometheux instance is accessible and running
  • Check if you’re behind a VPN or firewall that might be blocking access
  • Try again in a few moments — the server might be temporarily overloaded
