Troubleshoot Binlog MCP Startup

Explain why the plugin's binlog MCP server cannot connect and give an evidence-based, policy-safe recovery. This diagnoses the server launch, not failures recorded in a build. No binlog file or project build is needed.

This skill runs on demand. It cannot see a host error that was never exposed to the agent, inject session-start context, or guarantee activation merely because a plugin was installed.

1. Establish what failed

Use the user's error and any host MCP status or startup logs already available. CONNECTION_CLOSED alone says that the transport closed, not why. Do not translate it directly into "package missing."
