AI agents use close_list_activities to create or modify resources in Close Crm. 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 close_list_activities 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 Close Crm.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

List activities for a lead — calls, emails, notes, SMS, meetings, and status changes. Returns a data array (with id, _type, type, date_created, and type-specific fields) plus has_more / total_results. Requires lead_id. Page with _limit / _skip to walk a lead's timeline.. It is categorised as a Write tool in the Close Crm MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Close Crm MCP server in PolicyLayer and add a rule for close_list_activities: 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 Close Crm. Nothing to install.
close_list_activities 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 close_list_activities 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 close_list_activities. 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.
close_list_activities is provided by the Close Crm MCP server (https://gateway.pipeworx.io/close-crm/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
