Disable GitLab Orbit MCP Server

Disabled the GitLab Orbit MCP server and terminated background mcp-remote processes on rdmbair15m5, verifying absence fleet-wide.

Scope

• Host: rdmbair15m5 (with verification across all Mac fleet hosts: rdmsm4x, rdmbair13m5, rdmpw3265m, rdmpw3275m, jdmbair13m5)

Changes Made

1. Updated ~/.gemini/config/mcp_config.json on rdmbair15m5 to explicitly configure gitlab-orbit and gitlab as "disabled": true.
2. Terminated running background processes for mcp-remote https://gitlab.com/api/v4/orbit/mcp (PIDs 34170, 34194).
3. Verified port 22952 was released and no longer listening.
4. Confirmed no process respawned under Antigravity language_server.
5. Verified all 5 peer Mac fleet hosts have zero active gitlab-orbit processes, zero port listeners on 22952, and clean MCP configurations.

Verification Evidence

• pgrep -fli "gitlab|orbit" returned no matching processes.
• lsof -i :22952 returned empty / free across all fleet hosts.
• ~/.gemini/config/mcp_config.json verified with "disabled": true for gitlab-orbit and gitlab.

Undo

To re-enable: Set "disabled": false (or remove the "disabled": true property) for gitlab-orbit in ~/.gemini/config/mcp_config.json.
