WHAT IT DOES

What successful-tool does on Frontmcp

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

RISK

Why successful-tool is rated Low

The description is vague and appears to be a test/demo tool used for comparison purposes. It provides no information about what the tool actually does — no data access, no writes, no execution of commands. Given the framework context (FrontMCP is a TypeScript MCP framework), this is likely a stub or example tool.

RECOMMENDED RULE

The rule that runs successful-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 successful-tool, this is the rule to start with:

successful-tool Rate-limited

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