### `verify_token`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Token Trust Oracle. Call this BEFORE trading against, writing code that references, or reporting figures about any token contract address you were not given directly by the user (one you generated, recalled, or inferred). This closes two separate failure modes: address-poisoning/impersonation (an address that doesn't actually match the token name everyone assumes it is), and tokenomics hallucination (LLMs are documented to get total supply, circulating supply, and other figures wrong more often than almost any other crypto data point). Checks the address has real contract bytecode, cross-references CoinGecko for an independent listing, and compares on-chain totalSupply() against CoinGecko's reported figures. Pass expectedSymbol when you believe you know what token this is — a mismatch is the strongest possible signal something is wrong. Returns a synthetic verdict: ALLOW (no issues found), WARN (proceed with caution — read the findings), or BLOCK (do not trust this address — likely not a contract at all, or doesn't match the token it claims to be). First 5 calls per caller are free; after that this tool requires x402 payment (USDC on Base) and will return a payment-required error with the amount and address to pay.
```
