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

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

## Why modify_cell is rated Medium

The tool modifies cell content within Word document tables. This is a reversible write operation—the changes can be undone or overwritten. It does not delete data (would be Destructive), execute arbitrary code (would be Execute), or move money (would be Financial). The empty description lowers confidence slightly, but the name and server context provide sufficient indication of write-class functionality.

From the tool's own definition: "Tool name 'modify_cell' combined with server context showing 'editing' Word documents and sibling tools like 'add_comment', 'add_bookmark', 'add_content_control' that perform reversible modifications."

## Use case

AI agents use modify_cell to create or update resources in Docx, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Docx environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Docx:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "modify_cell": {
      "limits": [
        {
          "counter": "modify_cell_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
