WHAT IT DOES

What public-tool does on Frontmcp

AI agents call public-tool as a supporting operation in Frontmcp workflows.

RISK

Why public-tool is rated Low

The description states the tool has 'no authorities' and is accessible to everyone, but provides no information about what the tool actually does. There are no read, write, execute, destructive, or financial operations described. Given the complete lack of functional description, the safest classification is 'Other' with low confidence.

RECOMMENDED RULE

The rule that runs public-tool safely

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

public-tool Rate-limited

public-tool gets a rate cap, and everything else on the server is denied unless you say otherwise.
