AI agents call get_company to retrieve information from Twenty MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a simple data retrieval operation by fetching a company record from the CRM database using an identifier. It has no capability to modify, delete, or execute external operations. The blast radius of misuse is minimal—at worst, an AI agent could retrieve information about companies, which represents only unauthorized read access to existing data.
From the tool's definition Tool name is 'get_company' and description states 'Retrieve a company by ID from Twenty CRM' — explicitly a retrieval operation with no side effects.

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 get_company:
{
"version": "1",
"default": "deny",
"tools": {
"get_company": {}
}
}get_company is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
