WHAT IT DOES

What api_newman_run does on Zebbern Kali MCP

AI agents invoke api_newman_run to trigger actions in Zebbern Kali MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why api_newman_run is rated High

This tool executes network operations and API calls whose side effects depend entirely on the contents of the Postman collection and target endpoints provided. An AI agent could use this to invoke arbitrary API actions (create accounts, modify data, trigger workflows, exfiltrate information) against any reachable endpoint.

From the tool's definition Tool name 'api_newman_run' with description 'Run a Postman/Newman collection against API endpoints' indicates execution of HTTP requests against external systems based on provided collection/endpoint arguments.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs api_newman_run safely

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

api_newman_run Rate-limited

api_newman_run stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
