Repository

https://github.com/kerlenton/mcpsnoop

Selection Rationale

mcpsnoop (329 stars) is an MCP debugging proxy tool that helps developers monitor agent-server interactions in real-time. The You.com integration enhances the debugging workflow by allowing developers to search for error explanations, protocol specifications, and tool documentation directly from the TUI.

Integration Analysis

Implementation Type: Optional provider integration via new search module
Technical Approach: Added You.com API client with keyboard shortcuts and command support
Configuration: Environment variable (YOUCOM_API_KEY), CLI flag, and config file support
User Experience: 'w' key shortcut and ':search/:web' commands with overlay results display

PR: kerlenton/mcpsnoop#218

Integration Summary

• Setup: export YOUCOM_API_KEY=key or --youcom-api-key flag or config file
• Usage: Press 'w' for search prompt or ':search query' commands
• Results: Displays in TUI overlay consistent with other mcpsnoop panels
• Fallback: Graceful degradation when API key not provided

Validation Performed

• Code compiles and follows existing mcpsnoop patterns
• Configuration loading works (env var, flag, config file precedence)
• TUI integration follows existing overlay patterns
• Help text and documentation updated appropriately
• All existing functionality preserved when search not configured

Status

✅ COMPLETE - Implementation finished and PR submitted
⏳ PENDING - Awaiting maintainer review

The integration enhances MCP debugging by eliminating context switching - developers can research issues directly from their debugging session without leaving mcpsnoop.
