Tollary checks a short-lived owner mandate and exact unsigned Base USDC call. Nonce and expiry rules help reject replayed or stale authorization while the signer remains yours.
npx tollary inspect --source guide-mcp-duplicate
npx tollary lint --input ./guard-request.json --source guide-mcp-duplicateYour application must still be idempotent and verify the Tollary attestation. This is one independent check, not a complete wallet policy engine.
Testnet only. A lint cannot prove that no duplicate can occur elsewhere in your stack.
