AI agents use create_company 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 data in a CRM system but does not irreversibly delete data, execute arbitrary code, or move money. The action is reversible—companies can be modified or deleted by authorized users.
From the tool's definition Tool name 'create_company' and description 'Create a new company in Twenty CRM' indicate data creation that is reversible through standard CRM operations (update/delete).
Documented attack patterns abuse exactly the kind of access create_company 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 create_company:
{
"version": "1",
"default": "deny",
"tools": {
"create_company": {
"limits": [
{
"counter": "create_company_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_company 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.
