MCPGate (Tool Gateway)

The MCPGate serves as a robust tool gateway within the Lucid platform, providing essential features such as Role-Based Access Control (RBAC), audit logging, and credential injection. This gateway ensures secure and efficient routing of requests to various tools and services.

​
Workflow Overview

The request processing in MCPGate follows a structured workflow to ensure security, compliance, and efficient resource management. Here’s a step-by-step breakdown of the process:
  1. Request Authentication and Authorization:
    • Incoming requests are authenticated using Bearer tokens.
    • RBAC scopes are applied to ensure that the requestor has the necessary permissions to access the requested resources.
  2. Plan Enforcement:
    • The system checks the user’s subscription plan to enforce any limitations or special conditions associated with their plan.
  3. Quota Check:
    • Before routing the request, the system verifies that the user has not exceeded their allocated quota for the requested service or tool.
  4. Routing:
    • Requests are routed to either:
      • builtin:*: In-process services that are handled internally.
      • Registered servers: External services that are accessed via StreamableHTTP or Server-Sent Events (SSE).
  5. Tool Metering:
    • Usage of tools is metered to track consumption and ensure compliance with usage policies.
  6. Audit Logging:
    • All actions and requests are logged for auditing purposes, providing a detailed record of activities for security and compliance reviews.
  7. Response:
    • After processing, a response is generated and sent back to the requester, completing the request lifecycle.

​
Key Features

  • RBAC: Ensures that only authorized users can access specific tools and services, enhancing security.
  • Audit Logging: Provides a comprehensive log of all actions and requests for transparency and accountability.
  • Credential Injection: Automatically manages and injects necessary credentials for accessing various tools, simplifying the user experience.
By following this structured process, MCPGate ensures that all requests are handled securely, efficiently, and in compliance with user plans and quotas. This gateway is a critical component of the Lucid platform, facilitating seamless interaction with a wide range of tools and services.
