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

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

## Why findViewFieldDuplicates is rated Low

The tool appears to search for and return duplicate view field entries. The verb 'find' combined with 'request' indicates data retrieval with no side effects. No creation, modification, deletion, or execution of external operations is described. This is consistent with Read category tools that query and return data.

From the tool's own definition: "Tool name 'findViewFieldDuplicates' and description indicating it 'request[s] your viewField' suggests a query/search operation that retrieves or identifies duplicate records without modifying data."

## Use case

AI agents call findViewFieldDuplicates 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": {
    "findViewFieldDuplicates": {}
  }
}
```
