RISK

Why get_contract_roles is rated Low

This tool appears to retrieve role information from smart contracts, which is a read-only operation. The empty description and generic name 'get_contract_roles' are consistent with querying contract state. Given the server's focus on 'comprehensive smart contract analysis' (passive intelligence gathering), this fits the Read category.

From the tool's definition Tool name 'get_contract_roles' and server description indicating 'OpenZeppelin AccessControl role management' analysis suggests retrieving/querying contract role information. No side effects, modifications, or external operations described.
