AI agents call findTaskDuplicates 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 retrieves or identifies duplicate tasks within the CRM system. It queries existing data to find matches but does not create, modify, delete, or execute operations. The operation is read-only with no destructive or irreversible consequences. Severity is low because even if misused, it only exposes existing data without modifying state or causing harm.
From the tool's definition Tool name 'findTaskDuplicates' and description indicating it searches/queries for duplicate tasks; the word 'find' and 'request' suggest a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access findTaskDuplicates 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 findTaskDuplicates:
{
"version": "1",
"default": "deny",
"tools": {
"findTaskDuplicates": {}
}
}findTaskDuplicates is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

depth can be provided to request your task. 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 findTaskDuplicates: 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.
findTaskDuplicates 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 findTaskDuplicates 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 findTaskDuplicates. 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.
findTaskDuplicates 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.
