## Tools
- grant_covenant - Grant an agent a covenant: an explicit lease of authority. scopes support
    wildcards ('payments.*', '*'); budget_minor is the total spend ceiling in
    minor units; expires_at is ISO-8601. Returns the covenant_id. Endpoint: https://mcp.viridisconservation.com/covenant/mcp
- check_act - Check (and if allowed, record) a proposed act against a covenant.
    Deny-by-default. Idempotent on act_id — retries never double-consume
    budget. Every check lands on the audit chain. Endpoint: https://mcp.viridisconservation.com/covenant/mcp
- revoke_covenant - Revoke a covenant immediately and terminally. All subsequent checks deny. Endpoint: https://mcp.viridisconservation.com/covenant/mcp
- covenant_status - Current state, consumed/remaining budget, and check count. Endpoint: https://mcp.viridisconservation.com/covenant/mcp
- verify_audit - Verify the tamper-evident audit chain of allowed/denied acts. Endpoint: https://mcp.viridisconservation.com/covenant/mcp
- list_covenants - List covenants, optionally filtered by state (ACTIVE|REVOKED|EXPIRED)
    and/or the bound agent. Endpoint: https://mcp.viridisconservation.com/covenant/mcp
- describe_agent - Fleet-standard self-description. Endpoint: https://mcp.viridisconservation.com/covenant/mcp
