listMonitors
List monitors
Part of the Postman MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
WHEN AI AGENTS USE THIS TOOL
AI agents call listMonitors to retrieve information from Postman without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions — but you may still want rate limits to control API costs.
WHY ENFORCE A POLICY ON LISTMONITORS
Even though listMonitors only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
RECOMMENDED POLICY
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

FREQUENTLY ASKED QUESTIONS
What does the listMonitors tool do?
List monitors. It is categorised as a Read tool in the Postman MCP Server, which means it retrieves data without modifying state.
How do I enforce a policy on listMonitors?
Add a rule in your Intercept YAML policy under the tools section for listMonitors. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Postman MCP server.
What risk level is listMonitors?
listMonitors is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Can I rate-limit listMonitors?
Yes. Add a rate_limit block to the listMonitors rule in your Intercept policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
How do I block listMonitors completely?
Set action: deny in the Intercept policy for listMonitors. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
What MCP server provides listMonitors?
listMonitors is provided by the Postman MCP server (postmanlabs/postman-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
