What verify_bytes does on Algorand MCP

AI agents call verify_bytes to retrieve information from Algorand MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why verify_bytes is rated Low

Signature verification is a pure read operation used to authenticate data without creating, modifying, deleting, or executing any state-changing operations. The tool takes existing data (signature, bytes, address) and returns a boolean result. This is consistent with the Read category definition of retrieving or querying data with no side effects.

From the tool's definition Tool description states 'Verify a signature against bytes with an Algorand address'. Verification is a read-only cryptographic operation that checks whether a signature matches data and an address, with no side effects or state changes.

The rule that runs verify_bytes safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Algorand MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For verify_bytes, this is the rule to start with:

{
  "version": "1",
  "default": "deny",
  "tools": {
    "verify_bytes": {}
  }
}
