AI agents use createManyWorkflowRuns to create or update resources in Twenty MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Twenty MCP Server environment.
This tool creates new workflowRun objects in Twenty CRM. While creating workflow runs could potentially trigger automated processes (elevating risk), the primary action described is record creation, which is a Write operation. The blast radius is medium since bulk creation of workflow runs could spawn multiple automated processes or fill storage, but it is reversible in principle.
From the tool's definition "Create Many workflowRuns" - creates multiple workflow run records in the CRM
Documented attack patterns abuse exactly the kind of access createManyWorkflowRuns gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Twenty MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for createManyWorkflowRuns:
{
"version": "1",
"default": "deny",
"tools": {
"createManyWorkflowRuns": {
"limits": [
{
"counter": "createmanyworkflowruns_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}createManyWorkflowRuns 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.
