Problem:
The current mcp_bridge uses httpx.AsyncClient with its default 5-second timeout. When interfacing with LLM-backed endpoints (especially complex reasoning tasks or slow TTFT), this frequently triggers a TimeoutException, resulting in an isError response even when the backend is functioning correctly.
Solution:
Increased the httpx timeout to 300 seconds (5 minutes) to accommodate typical LLM processing times.
Implemented a structured httpx.Timeout(300.0, connect=10.0) for better connection management.
Added explicit error handling for httpx.TimeoutException to provide clearer feedback to the user.
Impact:
Improved stability for MCP-based workflows, particularly when using agents or slow upstream LLM APIs.
How to test:
Set up an MCP bridge pointing to a mock endpoint with a >5s delay.
Verified that the request now completes successfully instead of timing out at 5s.
Verified that requests exceeding 300s return the new descriptive error message.
