All-in-MCP FastMCP Proxy Server
This server uses ProxyClient to automatically proxy requests to the APaper server
and other MCP servers with advanced features like LLM sampling forwarding,
progress reporting, and logging.
Environment variables to enable MCP servers (all disabled by default):
- ENABLE_APAPER=true: Enable APaper academic search server
- ENABLE_GITHUB_REPO_MCP=true: Enable GitHub repository MCP server
- ENABLE_QWEN_SEARCH=true: Enable Qwen/Dashscope web search server
