AI agents call list_delivery_services to retrieve information from Keycrm without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a data retrieval operation only. It lists existing delivery services (ID and name metadata) without creating, modifying, deleting, executing code, or initiating financial transactions. The blast radius of misuse is minimal—an AI agent listing delivery services causes no harm to data integrity, business operations, or financial state.
From the tool's definition Tool name contains 'list' and description states 'List all available delivery services with their IDs and names' — a read-only query operation that retrieves configuration data with no side effects.

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