## Tools (11)

- `cancel_mandate`: Stops checks and events for a mandate, e.g. after selling the token.
- `create_mandate`: For a token you hold: $0.05 per 7 days over x402 (pay via the REST API or the stdio MCP server). Re-checks a token against the policy about every 30 minutes. Changes (decision, owner, implementation, mint/pause/blacklist, supply) are recorded as events you poll with mandate_events; optionally also POSTed to an https webhook. Every event carries a signed signal: exit, watch or hold. Returns an id and a secret: keep the secret.
- `gate`: Call BEFORE buying a token on Robinhood Chain. Returns ALLOW, DENY or REVIEW, every check with the fact it read, and an EIP-712 signed receipt. Missing data never gives ALLOW unless the policy says so.
- `gate_batch`: Gate up to 10 tokens against one policy in one call, one receipt each. Counts as one Gate call per token.
- `gate_facts`: Every fact a policy rule may use (name, type, meaning), the rule syntax, the presets, and current pricing.
- `get_receipt`: A stored decision receipt by id (rcpt_…).
- `mandate_events`: Events a mandate recorded since a unix time (0 = all). Use next_since for the following poll.
- `mandate_signal`: The newest signed signal for a mandate: exit, watch or hold, from its last decision, valid for one hour. Verify it, then your own code decides whether to sell; Actuary never trades.
- `mandate_status`: Current decision, delivery mode, last check and failures of a mandate.
- `verify_receipt`: Checks that a receipt was signed by Actuary and that nothing in it changed. Pass the receipt object or its id.
- `verify_signal`: Checks that a mandate signal was signed by Actuary, that nothing in it changed and that it is still fresh. Act only on valid and fresh.
