Low Risk

list_events

List calendar events in a time range. Returns events in TOON or JSON format.

Part of the Temporal Cortex MCP MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

AI agents call list_events to retrieve information from Temporal Cortex MCP 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.

Even though list_events 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.

Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

What does the list_events tool do? +

List calendar events in a time range. Returns events in TOON or JSON format.. It is categorised as a Read tool in the Temporal Cortex MCP MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on list_events? +

Add a rule in your Intercept YAML policy under the tools section for list_events. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Temporal Cortex MCP MCP server.

What risk level is list_events? +

list_events is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit list_events? +

Yes. Add a rate_limit block to the list_events 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 list_events completely? +

Set action: deny in the Intercept policy for list_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.

What MCP server provides list_events? +

list_events is provided by the Temporal Cortex MCP MCP server (temporal-cortex/cortex-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
