AMP Server

An AI service proxy server with support for custom forwarding interfaces, featuring a clean architecture and flexible configuration system after refactoring.

Architecture Overview

Main Components

• proxy module: Unified proxy system supporting custom forwarding interfaces and headers
• user module: User-related mock endpoints
• telemetry module: Telemetry data collection endpoints

Unified Proxy System

The new proxy system supports: - Custom forwarding endpoints via YAML configuration files - Custom request and response headers per endpoint - Multiple response types: JSON, SSE, streaming, HTML - Dynamic route registration

Configuration

Proxy Configuration File (proxy_config.yaml)

endpoints:
  - path: "/api/provider/openai/v1/chat/completions"
    target_url: "https://api.openai.com/v1/chat/completions"
    method: "POST"
    response_type: "stream"
    custom_headers: {}
    forward_request_headers:
      - "authorization"
      - "content-type"
    forward_response_headers:
      - "content-type"
    enabled: true

Environment Variables

• HOST: Server bind host
• PORT: Server port
• AMP_API_KEY: AMP service authentication key
• RUST_LOG: Log level

Usage

Starting the Server

cargo run

Adding Custom Endpoints

1. Edit the proxy_config.yaml file
2. Add new endpoint configuration
3. Restart the server

Endpoint Configuration Parameters

• path: Local route path
• target_url: Target forwarding URL
• method: HTTP method (GET, POST, PUT, DELETE)
• response_type: Response type (json, sse, stream, html)
• custom_headers: Custom request headers
• forward_request_headers: List of request headers to forward
• forward_response_headers: List of response headers to forward
• enabled: Whether this endpoint is enabled

API Endpoints

Proxy Endpoints (Configurable)

• /api/provider/openai/v1/chat/completions - OpenAI compatible interface
• /api/provider/anthropic/v1/messages - Anthropic compatible interface
• /api/tab/llm-proxy - LLM proxy interface

User Endpoints

• GET /api/user - Get user information
• GET /api/connections - Get connection list
• POST /api/threads/sync - Sync conversations
• POST /api/internal - Internal interface

Telemetry Endpoints

• POST /api/telemetry - Send telemetry data
