The severity is medium because incorrect lead creation could pollute the CRM database and affect business processes, but the operation is reversible through updates or deletion by other tools.
From the tool's definition Tool name is 'create_lead' and description states 'Criar um novo lead no Kommo CRM' (Create a new lead in Kommo CRM). The verb 'create' and 'novo' (new) indicate data creation.
Documented attack patterns abuse exactly the kind of access create_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 create_lead:
{
"version": "1",
"default": "deny",
"tools": {
"create_lead": {
"limits": [
{
"counter": "create_lead_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_lead stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
