}Monitor all of Robinhood's stock tokens in one call: integrity incidents, newest first. An incident is a token whose supply or treasury balance diverged from its full mint/burn ledger, or a ledger rebaseline, with its type, status and block window. type=integrity (default), operational (collector errors) or all. On-chain observations and reconciliation findings, not financial advice. Costs $0.005 per call, paid with x402 (USDC on Base or Arbitrum One).
| Argument | Type | Description |
|---|---|---|
| type | string | integrity (default), operational or all. |
| limit | integer | Page size, 1-100 (default 20). |

On-chain observations reconstructed from chain event logs, not financial advice. Costs $0.005 per call, paid with x402 (USDC on Base or Arbitrum One).

}Verify a Robinhood stock token's state at a past block: total supply, treasury balance and multiplier from the newest confirmed snapshot at or before it. Use it to check a historical position, report or trade against what was on-chain then. Pass a ticker or contract address and block=<number>. On-chain observations reconstructed from chain event logs, not financial advice. Costs $0.01 per call, paid with x402 (USDC on Base or Arbitrum One).

}We read every tool's name, description and inputs the way the model will, looking for instructions hidden from you. A clean result means no warning signs, not a guarantee. Scanned Nov 5, 2026.
Takes a password, API key or token as an argument, so the secret passes through the model's context and chat logs.
Fix: Read credentials from the server's own configuration (environment, OAuth) instead of a tool argument.
