AI agents call get_lead 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 lead record from the Kommo CRM system using an ID parameter. It performs a read-only query operation with no side effects, no data modification, no code execution, and no destructive actions. The only risk is potential unauthorized access to lead data if credentials are compromised, which is a standard low-severity read operation risk.
From the tool's definition Tool name 'get_lead' and description 'Obter um lead específico pelo ID' (Get a specific lead by ID) indicate data retrieval by identifier with no modification or execution.
Documented attack patterns abuse exactly the kind of access get_lead gives an agent:
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_lead:
{
"version": "1",
"default": "deny",
"tools": {
"get_lead": {}
}
}get_lead is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Obter um lead específico pelo ID. It is categorised as a Read tool in the Kommo CRM MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Kommo CRM MCP Server MCP server in PolicyLayer and add a rule for get_lead: 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 Kommo CRM MCP Server. Nothing to install.
get_lead 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 get_lead 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 get_lead. 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.
get_lead is provided by the Kommo CRM MCP Server MCP server (miguelgbastos/kommo-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Kommo CRM MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
