Known Issues and Workarounds

• search_arena may hit 403 on v3 endpoints for premium-gated contexts. By default the server retries via v2 when ARENA_ENABLE_V2_SEARCH_FALLBACK=true.

• Remote HTTP clients must send Accept: application/json, text/event-stream during MCP initialize, or you can get 406 Not Acceptable.

• Missing/invalid auth keys on HTTP mode return 401 Unauthorized on /mcp.
