This tool queries and retrieves viewField metadata with optional filtering and pagination. It has no side effects, does not create, modify, or delete data, and does not execute arbitrary code. It is a pure read operation typical of CRM data retrieval endpoints.

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 findManyViewFields:
{

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

findManyViewFields is provided by the Twenty MCP Server MCP server (jdu278/twenty-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Twenty MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
