🐞 Bug Summary

I'm running the official GH MCP server locally using mcpgateway.translate (via cforge run). When I run a tool, I see LimitOverrunError.

🧩 Affected Component

Select the area of the project impacted:

• mcpgateway - API
• mcpgateway - UI (admin panel)
• mcpgateway.wrapper - stdio wrapper
• Federation or Transports
• CLI, Makefiles, or shell scripts
• Container setup (Docker/Podman/Compose)
• Other (explain below)

🔁 Steps to Reproduce

1. Running the GH MCP server locally via cforge run (which directly wraps mcpgateway.translate:

cforge run --stdio "docker run --rm -i -e GITHUB_PERSONAL_ACCESS_TOKEN=$GITHUB_PUBLIC_TOKEN ghcr.io/github/github-mcp-server" --port 8003 --temporary

2. Invoke a tool with lots of results (search-pull-requests with query set to author:gabe-l-hart merged:>2026-01-01)

3. Error processing stdio async stream

During handling of the above exception, another exception occurred:

🤔 Expected Behavior

Tool response should be handled correctly
