Summary

  • Updates github.com/mark3labs/mcp-go from v0.39.0 to v0.39.1
  • Fixes issue with outputSchema breaking MCP specification compliance

Details

This update includes the fix from mark3labs/mcp-go#573 which resolves an issue where empty output schemas were being returned improperly, breaking the MCP specification. The fix ensures that when no output schema is specified, the outputSchema field is omitted entirely rather than returning an empty schema object.

Test plan

  • Dependency updated successfully
  • go mod tidy executed without errors
  • Build and tests pass (pending CI)
