## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "findViewFilterDuplicates",
    "arguments": {}
  }
}
```

## Why findViewFilterDuplicates is rated Low

The verb 'find' combined with the description indicating it requests/retrieves viewFilter data indicates this is a read-only operation that queries or retrieves existing CRM view filter data. No creation, modification, deletion, or execution of external operations is implied. Despite the generic description, the naming pattern is consistent with read operations among sibling write tools (createMany*).

From the tool's own definition: "Tool name 'findViewFilterDuplicates' uses 'find' verb and description indicates it 'request[s] your viewFilter', suggesting a query/retrieval operation with no modification capability."

## Use case

AI agents call findViewFilterDuplicates to retrieve information from Twenty MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Twenty MCP Server:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "findViewFilterDuplicates": {}
  }
}
```
