AI agents call list_monitors to retrieve information from Uptrack without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns information about existing monitors (status, URL, interval, uptime). It performs no side effects, creates no new resources, executes no code, and makes no changes to the system. It is purely informational retrieval, which is the definition of a Read category tool.
From the tool's definition Tool name 'list_monitors' and description 'List all monitors with their status, URL, interval, and uptime' indicate a retrieval operation that returns status data without modifying state.
Attacks that exploit this kind of access
List all monitors with their status, URL, interval, and uptime. It is categorised as a Read tool in the Uptrack MCP Server, which means it retrieves data without modifying state.
Register the Uptrack MCP server in PolicyLayer and add a rule for list_monitors: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Uptrack. Nothing to install.
list_monitors is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_monitors rule in your PolicyLayer 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.
Set action: deny in the PolicyLayer policy for list_monitors. 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.
list_monitors is provided by the Uptrack MCP server (uptrack-app/uptrack-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
