## MCP tools (5)

### `gvnr_request_permission` (~136 tokens)

Ask GVNR before acting

Ask GVNR whether an action is allowed BEFORE you run it. Call this before any shell command, file deletion, git push, deploy or publish, and before reading or writing credentials. Returns allow, deny, or ask_human. On deny, do not run the action. On ask_human, stop and get approval from the person you are working for before running it. Every call is recorded in a hash-chained receipt.

Input parameters:

- `action` (string, required): Exactly what you are about to do: the full shell command, or for a file operation the verb and path, e.g. "write /app/.env".

### `gvnr_status` (~40 tokens)

GVNR status

Show every governed agent with its status, spend and spend rate, plus the limits in force and what has been spent today, this week and this month.

### `gvnr_recent_decisions` (~45 tokens)

Recent GVNR decisions

List the most recent allow, deny and ask decisions from the receipt file, newest last.

Input parameters:

- `limit` (integer): How many to return. Defaults to 20.

### `gvnr_verify_receipts` (~37 tokens)

Verify the receipt chain

Check the hash chain over every recorded decision. Reports whether it is intact, or the line where a record was edited or removed.

### `gvnr_stop_agent` (~54 tokens)

Stop an agent

Stop a governed agent immediately. Only a human can resume it, from the GVNR dashboard. Use gvnr_status for agent ids.

Input parameters:

- `agent` (string, required): The agent id, as shown by gvnr_status.
