Is colr-guardrail live?

Yes — it answered the hub's last check (checked 14h ago). It answered 25% of checks over the last 30 days.

Is colr-guardrail free to use?

Not measured yet.

What tools does colr-guardrail have?

6 tools: get_supported_assets, evaluate_trade, evaluate_trade_paid, simulate_balance, check_token_safety, verify_audit_trail.

Is colr-guardrail safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• get_supported_assets unknown never probed

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

• evaluate_trade unknown never probed

  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). For higher limits, use `evaluate_trade_paid` (Tier 2, $25,000) which settles an x402 payment on-chain.

• evaluate_trade_paid unknown never probed

  Pre-trade risk check gated by an x402 payment. Evaluated as COLR Tier 2: $25,000 notional ceiling, 10/25 per-minute rate limits. No COLR holdings are required — the on-chain payment is the credential. FLOW ---- 1. Call WITHOUT payment_proof → the tool returns a `PaymentRequiredOutput` describing the on-chain payment (network, asset, amount, payTo, resource). 2. Settle the payment on-chain using an x402-capable client. The facilitator returns a proof string. 3. Call again with `payment_proof=<proof>` → the tool forwards the proof to the guardrail's x402-paid endpoint and returns a full `EvaluateTradeOutput` with `tier=2`.

• check_token_safety unknown never probed

  Honeypot / contract safety check for any ERC-20 token. Returns a severity classification (safe / warn / danger), the specific risk factors detected, and the result of a simulated sell. When severity=danger, the next `evaluate_trade` for the same contract is automatically denied regardless of any other checks. This is a heuristic bytecode + simulation check, not a formal audit. Use it before trading unknown tokens, memecoins, or any contract that is absent from the official Robinhood Chain registry. It is safe to call repeatedly; no transaction is ever sent.
