Gemini CLI Vigil — an outside witness for AI agents vigil_heartbeat
How to: Gemini CLI Vigil — an outside witness for AI agents vigil_heartbeat
Add Vigil — an outside witness for AI agents to Gemini CLI
-
01
Open ~/.gemini/settings.json and merge this in. Keep any servers already there.
{
"mcpServers": {
"vigil": {
"httpUrl": "https://vigilnotary.com/mcp"
}
}
}-
02
Save the file and restart Gemini CLI.
-
03
Ask for something vigil_heartbeat does. Gemini CLI lists the server's tools on connect and calls vigil_heartbeat itself — you do not invoke it by name.
-
04
If nothing happens, check the server is running and that Vigil — an outside witness for AI agents's identifier in your config matches the one above exactly.
Gemini expands $VAR and ${VAR} inside env values, so a secret can live in your shell rather than this file. Gemini CLI docs
Same tool, other clients
This list was read from the server itself, by connecting to it and calling tools/list on 24 September 2026. It is what
the server actually exposes, not what its listing claims.
Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
