AI agents use update_property 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_property 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 property in Propstack CRM. Use this tool to: - Update the price or rent - Change property status (e.g. mark as reserved or sold) - Edit description texts - Assign to a different broker or project - Update custom fields Only provide the fields you want to change. Use get_property_statuses to look up valid status IDs.. 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_property: 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_property 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_property 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_property. 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_property 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.
