Backend tools (5)

write = sends, deletes, buys or posts
  • check_token_safetyFree

    Honeypot / contract safety check for any ERC-20 token.

  • evaluate_tradeFree

    Pre-trade risk check for a proposed trade. Call this BEFORE executing any trade and treat a "deny" decision as a hard stop. Evaluated at a fixed Tier 1 ceiling ($5,000 notional) — MCP callers do not get COLR tier gating. For higher tiers, use the REST API with wallet-signature authentication.

  • get_supported_assetsFree

    List every asset in the guardrail's official Robinhood Chain registry, with its canonical contract address.

  • simulate_balanceFree

    Simulate a wallet's ERC-20 balance after a hypothetical trade using eth_call state override. Read-only: no transaction is ever sent.

  • verify_audit_trailFree

    Verify the tamper-evident audit trail for a wallet's past guardrail decisions.
