AI agents use create_task to create or update resources in Twenty CRM MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Twenty CRM MCP Server environment.
This tool creates new task records in the CRM system. Creation is reversible (tasks can be deleted via delete_task), so it is classified as Write rather than Destructive. Severity is medium because misuse could create many spurious tasks, cluttering workflows and potentially triggering downstream automation, but the impact is limited compared to destructive or financial operations.
From the tool's definition Tool name is 'create_task' and description states 'Create a new task in Twenty CRM'. The verb 'create' explicitly indicates data creation, which is a write operation.
Documented attack patterns abuse exactly the kind of access create_task gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Twenty CRM MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create_task:
{
"version": "1",
"default": "deny",
"tools": {
"create_task": {
"limits": [
{
"counter": "create_task_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_task 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.
