Run manage_accounts list to | | `linkUrl` | string | no | URL for hyperlink | | `endIndex` | number | no | End index (exclusive) - use with startIndex | | `fontSize` | number | no | Font size in points | | `underline` | boolean | no | Underline text | | `documentId` | string | yes | The document ID | | `fontFamily` | string | no | Font family name | | `startIndex` | number | no | Start index (1-based) - use with endIndex | | `textToFind` | string | no | Text to find and format (alternative to indices) | Parameters from the server's own tool schema. ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "applyTextStyle", "arguments": { "documentId": "" } } } ``` ## Why applyTextStyle is rated Medium This tool creates or modifies document data reversibly. Text formatting changes can be undone and do not permanently destroy data or execute arbitrary code. It affects Google Docs/Sheets content but is narrowly scoped to cosmetic formatting rather than structural changes or data deletion. From the tool's own definition: "Tool description states 'Apply text formatting' which modifies document content. The mechanism uses 'startIndex+endIndex OR textToFind for targeting' to select and alter text properties (bold, italic, color, etc.)." Risk signals: High parameter count (18 properties) ## Use case AI agents use applyTextStyle to create or update resources in Google Drive, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Google Drive environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
