# style_text

Applies character formatting to [start_index, end_index): bold, italic, underline, strikethrough, small_caps, font_size (points), font_family (e.g. "Roboto"), foreground_color/background_color (6-digit hex), link_url (empty string removes an existing link) and baseline_offset (superscript/subscript/none). Only the provided fields change (the fields mask is computed); at least one is required. Explicit false turns a toggle off. Get indexes from read_document_text. Styling does not shift indexes, so several style calls can safely reuse the same coordinates.

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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "style_text",
    "arguments": {
      "end_index": 0,
      "document_id": "<document_id>",
      "start_index": 0
    }
  }
}
```

## Why style_text is rated Low

Even though style_text only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Risk signals: High parameter count (16 properties)

## Use case

AI agents call style_text to retrieve information from Mcp Google Docs 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 Mcp Google Docs:

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