One reports a bug where connections close after the handshake, and the others propose different approaches: using direct parent identity, skipping watchdog wrapping for launchers, or adding a disable option.","subsystem":null,"counts":{"members":4,"open_issues":0,"open_issues_distinct":0,"open_prs":0,"closed_issues":1,"merged_prs":1,"attempt_prs":2},"landed_fix":{"status":"merged_to_main","basis":"structural","pr":66858,"merged_at":"2026-07-18T11:15:14+00:00"},"resolution":{"state":"resolved","by":"pr-66858"},"freshness":{"state":"verified","last_verified_at":"2026-07-18T11:15:14+00:00","is_stale":false},"grouping":{"backbone":"STRUCTURAL_SPANNING","link_density":0.5},"fix_edges":[{"issue_number":62505,"pr_number":66858,"tier":"verified","basis":"closing_ref","confidence":0.95,"recoverable_from_timeline":true,"pr_merged_at":"2026-07-18T11:15:14+00:00"},{"issue_number":66423,"pr_number":66858,"tier":"verified","basis":"closing_ref","confidence":0.95,"recoverable_from_timeline":true,"pr_merged_at":"2026-07-18T11:15:14+00:00"},{"issue_number":66518,"pr_number":66858,"tier":"verified","basis":"closing_ref","confidence":0.95,"recoverable_from_timeline":true,"pr_merged_at":"2026-07-18T11:15:14+00:00"}],"members":[{"kind":"issue","number":66423,"title":"[Bug]: mcp_stdio_watchdog breaks uvx-based MCP servers — \"Connection closed\" after handshake","url":null,"state":"closed"},{"kind":"pr","number":66430,"title":"fix(mcp): skip watchdog wrapping for launcher commands (uvx, npx, etc.) (#66423)","url":null,"state":"closed","close_reason":{"refs":[{"kind":"pr","value":"#66858","number":66858},{"kind":"pr","value":"#66423","number":66423}],"category":"uncategorized","implication":"needs_llm"},"merged":false},{"kind":"pr","number":66805,"title":"fix(mcp): add disable_watchdog config option for uvx servers (#66423)","url":null,"state":"closed","close_reason":{"refs":[{"kind":"pr","value":"#66858","number":66858}],"category":"implemented_elsewhere","implication":"superseded"},"merged":false},{"kind":"pr","number":66858,"title":"fix(mcp): use direct parent identity in watchdogs — stop false-killing live stdio servers (#62505, #66518, #66423)","url":null,"state":"merged","close_reason":{"category":"merged"},"merged":true,"is_fix_pr":true,"fix_tier":"verified","files_changed":["contributors/emails/[redacted:email]","tests/test_slash_worker_watchdog.py","tests/tools/test_mcp_stdio_watchdog.py","tools/mcp_stdio_watchdog.py","tools/mcp_tool.py","tui_gateway/slash_worker.py"]}],"trust":{"default_tier":"verified","includes_suggested":false}}
