AI agents call get_loss_reason to retrieve information from Kommo CRM MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves a single loss reason record from the CRM system based on an ID parameter. It is a straightforward read operation with no side effects, consistent with other data retrieval tools on the server (get_account, get_lead, get_leads, get_contacts, get_companies, get_dashboard).
From the tool's definition Tool name 'get_loss_reason' and description 'Obter um motivo de perda específico pelo ID' (Get a specific loss reason by ID) indicate a retrieval operation that fetches data by identifier without modifying, deleting, or executing external operations.

PolicyLayer is an MCP gateway — it sits between your AI agents and Kommo CRM MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_loss_reason:
{
"version": "1",
"default": "deny",
"tools": {
"get_loss_reason": {}
}
}get_loss_reason is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
