AI agents call eventTimeline to retrieve information from Routine without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays event information in an agenda format without modifying, executing, or deleting any data. It is a read-only query operation with no side effects, consistent with other Read category tools like 'eventGet' and 'calendarGet' on the same server.
From the tool's definition Tool name 'eventTimeline' and description 'Agenda view for a day' indicate retrieval of calendar/event data for viewing purposes only.
Attacks that exploit this kind of access

Register the Routine MCP server in PolicyLayer and add a rule for eventTimeline: 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 Routine. Nothing to install.
eventTimeline 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 eventTimeline 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 eventTimeline. 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.
eventTimeline is provided by the Routine MCP server (routineco/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
