AI agents use update_task to create or modify resources in Propstack. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call update_task repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Propstack.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Update an existing task in Propstack. Use this tool to: - Mark a to-do as done - Reschedule an appointment (change starts_at/ends_at) - Add notes to an existing task (update body) - Change broker assignment - Update event state (took_place, cancelled) - Link additional contacts or properties Only provide the fields you want to change.. It is categorised as a Write tool in the Propstack MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Propstack MCP server in PolicyLayer and add a rule for update_task: 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 Propstack. Nothing to install.
update_task is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the update_task 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 update_task. 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.
update_task is provided by the Propstack MCP server (propstack-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
