List CTFtime events in a time window. Uses UNIX timestamps (seconds) for start/finish; returns past and upcoming events.
AI agents call ctftime_events to retrieve information from Mcp Ctftime without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and returns event data from CTFtime.org. It performs no writes, executions, or destructive actions. The blast radius of misuse is negligible as it only fetches read-only public data.
From the tool's definition "List CTFtime events in a time window" and "returns past and upcoming events" — purely retrieves data from the CTFtime API with no side effects.
Attacks that exploit this kind of access
List CTFtime events in a time window. Uses UNIX timestamps (seconds) for start/finish; returns past and upcoming events. It is categorised as a Read tool in the Mcp Ctftime MCP Server, which means it retrieves data without modifying state.
Register the Mcp Ctftime MCP server in PolicyLayer and add a rule for ctftime_events: 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 Mcp Ctftime. Nothing to install.
ctftime_events 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 ctftime_events 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 ctftime_events. 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.
ctftime_events is provided by the Mcp Ctftime MCP server (tomek7667/mcp-ctftime). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
