AI agents call schedule_list to retrieve information from Semaphore without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool only retrieves and lists schedule data from a project without modifying, creating, or deleting anything. Pure read operation with minimal blast radius.
From the tool's definition List all schedules in a project
Attacks that exploit this kind of access
List all schedules in a project. It is categorised as a Read tool in the Semaphore MCP Server, which means it retrieves data without modifying state.
Register the Semaphore MCP server in PolicyLayer and add a rule for schedule_list: 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 Semaphore. Nothing to install.
schedule_list 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 schedule_list 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 schedule_list. 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.
schedule_list is provided by the Semaphore MCP server (vitexsoftware/semaphore-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
