# get_thumbnail Renders one page (slide, layout or master) as a PNG. Without output_path it returns contentUrl + width/height — the URL is short-lived (~30 minutes) and served from googleusercontent.com. With output_path the PNG is downloaded and saved to that local file instead (the download is restricted to Google's image hosts). size: large (1600px, default), medium (800px) or small (200px). This is the way to SEE what a slide actually looks like — the JSON never shows rendering. Counts as an expensive read in the API quota.

From the tool's own definition: "Renders one page as a PNG, returns contentUrl or downloads to local file." ## Use case AI agents call get_thumbnail to retrieve information from Mcp Google Slides 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 Slides: ```json { "version": "1", "default": "deny", "tools": { "get_thumbnail": {} } } ``` ## Other tools on Mcp Google Slides (25) - `delete_object` — Destructive — https://policylayer.com/tools/a1-x-tech-mcp-google-slides/delete-object.md - `edit_table` — Destructive — https://policylayer.com/tools/a1-x-tech-mcp-google-slides/edit-table.md - `manage_comments` — Destructive — https://policylayer.com/tools/a1-x-tech-mcp-google-slides/manage-comments.md - `batch_update` — Execute — https://policylayer.com/tools/a1-x-tech-mcp-google-slides/batch-update.md - `raw_request` — Execute — https://policylayer.com/tools/a1-x-tech-mcp-google-slides/raw-request.md - `get_page` — Read — https://policylayer.com/tools/a1-x-tech-mcp-google-slides/get-page.md - `get_presentation` — Read — https://policylayer.com/tools/a1-x-tech-mcp-google-slides/get-presentation.md - `get_speaker_notes` — Read — https://policylayer.com/tools/a1-x-tech-mcp-google-slides/get-speaker-notes.md - `list_layouts` — Read — https://policylayer.com/tools/a1-x-tech-mcp-google-slides/list-layouts.md - `list_slides` — Read — https://policylayer.com/tools/a1-x-tech-mcp-google-slides/list-slides.md - `add_slide` — Write — https://policylayer.com/tools/a1-x-tech-mcp-google-slides/add-slide.md - `create_image` — Write — https://policylayer.com/tools/a1-x-tech-mcp-google-slides/create-image.md - `create_presentation` — Write — https://policylayer.com/tools/a1-x-tech-mcp-google-slides/create-presentation.md - `create_shape` — Write — https://policylayer.com/tools/a1-x-tech-mcp-google-slides/create-shape.md - `create_table` — Write — https://policylayer.com/tools/a1-x-tech-mcp-google-slides/create-table.md - `duplicate_slide` — Write — https://policylayer.com/tools/a1-x-tech-mcp-google-slides/duplicate-slide.md - `export_presentation` — Write — https://policylayer.com/tools/a1-x-tech-mcp-google-slides/export-presentation.md - `insert_text` — Write — https://policylayer.com/tools/a1-x-tech-mcp-google-slides/insert-text.md - `move_slides` — Write — https://policylayer.com/tools/a1-x-tech-mcp-google-slides/move-slides.md - `replace_image` — Write — https://policylayer.com/tools/a1-x-tech-mcp-google-slides/replace-image.md - `replace_text` — Write — https://policylayer.com/tools/a1-x-tech-mcp-google-slides/replace-text.md - `set_speaker_notes` — Write — https://policylayer.com/tools/a1-x-tech-mcp-google-slides/set-speaker-notes.md - `set_text` — Write — https://policylayer.com/tools/a1-x-tech-mcp-google-slides/set-text.md - `update_text_style` — Write — https://policylayer.com/tools/a1-x-tech-mcp-google-slides/update-text-style.md - `update_transform` — Write — https://policylayer.com/tools/a1-x-tech-mcp-google-slides/update-transform.md ## For agents This record is a snapshot.
