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

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

  }
}

## Why client_update is rated Medium

This tool creates or modifies client data reversibly without deletion. While it accesses personal information (moderate sensitivity), the constraint that 'Email cannot be changed via MCP' suggests appropriate safeguards are in place. The impact is limited to updating individual client records rather than bulk operations or irreversible destruction.

From the tool's own definition: "Tool name 'client_update' and description 'Update an existing client's personal data' indicate modification of existing data records."

Risk signals: Handles credentials or secrets (apiKey) · High parameter count (11 properties)

## Use case

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