depth can be provided to request your workflowVersion
AI agents call findWorkflowVersionDuplicates 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.
The tool performs a lookup or search for duplicate workflow versions without modifying, deleting, or executing external operations. Despite the vague description, the verb 'find' and the context of querying workflow duplicates classify this as a Read operation with low blast radius if misused by an AI agent.
From the tool's definition Tool name 'findWorkflowVersionDuplicates' indicates a search/query operation. Description mentions requesting/retrieving 'workflowVersion' data with a depth parameter, which is consistent with read-only retrieval of duplicate records.
Documented attack patterns abuse exactly the kind of access findWorkflowVersionDuplicates 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 findWorkflowVersionDuplicates:
{
"version": "1",
"default": "deny",
"tools": {
"findWorkflowVersionDuplicates": {}
}
}findWorkflowVersionDuplicates is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
depth can be provided to request your workflowVersion. It is categorised as a Read tool in the Twenty MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Twenty MCP Server MCP server in PolicyLayer and add a rule for findWorkflowVersionDuplicates: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Twenty MCP Server. Nothing to install.
findWorkflowVersionDuplicates is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the findWorkflowVersionDuplicates rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for findWorkflowVersionDuplicates. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
findWorkflowVersionDuplicates 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.
