WHAT IT DOES

What replace_image does on Mcp Google Slides

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

Parameter	Type	Required	Description
`image_url`	string	—	Public https URL of the new PNG/JPEG/GIF (exactly one of image_url / image_path).
`image_path`	string	—	Absolute local path of the new image (exactly one of image_url / image_path).
`replace_method`	string	—	How the new image fills the old frame (default center_inside).
`image_object_id`	string	Yes	The existing image element's object id (type "image" in list_slides).
`presentation_id`	string	Yes	The presentation id — the long id from the URL (docs.google.com/presentation/d/<presentationId>/edit) or from create_presentation output.

Parameters from the server's own tool schema.

RECOMMENDED RULE

The rule that runs replace_image safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp Google Slides, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For replace_image, this is the rule to start with:

replace_image Rate-limited

replace_image stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about replace_image

What does the replace_image tool do? +

Swaps the bitmap of an existing image element while keeping its frame, position and effects (batchUpdate replaceImage). The new picture comes from image_url or image_path with exactly the same validation/upload/cleanup rules as create_image. replace_method: center_inside (default — scales to fit inside the frame, keeping aspect) or center_crop (fills the frame, cropping the overflow). It is categorised as a Write tool in the Mcp Google Slides MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does replace_image accept? +

replace_image accepts 5 parameters: image_url, image_path, replace_method, image_object_id, presentation_id. Required: image_object_id, presentation_id. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on replace_image? +

Register the Mcp Google Slides MCP server in PolicyLayer and add a rule for replace_image: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Mcp Google Slides. Nothing to install.

What risk level is replace_image? +

replace_image is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit replace_image? +

Yes. Add a rate_limit block to the replace_image rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block replace_image completely? +

Set action: deny in the PolicyLayer policy for replace_image. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides replace_image? +

replace_image is provided by the Mcp Google Slides MCP server (@a1-x-tech/mcp-google-slides). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
