WHAT IT DOES

What insert_image does on Mcp Google Docs

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

Parameter	Type	Required	Description
`uri`	string	Yes	Public image URL (PNG/JPEG/GIF, <=50 MB, <=25 MP; fetched by Google, not this server).
`index`	integer	—	Insertion index (from read_document_text). Omit to append at the end.
`tab_id`	string	—	Tab to target (from list_tabs). Omit for the first/only tab.
`width_pt`	number	—	Displayed width in points.
`height_pt`	number	—	Displayed height in points.
`segment_id`	string	—	Header/footer/footnote segment id (from get_document). Omit for the document body.
`document_id`	string	Yes	The document id — the long id from the document URL (docs.google.com/document/d/<documentId>/edit) or from create_document output.

Parameters from the server's own tool schema.

RISK

Why insert_image is rated Medium

An AI agent can call insert_image faster than any human can review: one bad instruction and it creates or modifies resources in Mcp Google Docs by the hundred, each call as confident as the last.

RECOMMENDED RULE

The rule that runs insert_image safely

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

insert_image Rate-limited

insert_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.

{

          "counter": "insert_image_rate",
          "window": "minute",
          "max": 30,

        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Mcp Google Docs, apply this rule, and every insert_image call is checked against it from then on.

FAQ

Questions about insert_image

What does the insert_image tool do? +

Inserts an inline image fetched from a PUBLIC URL at an index (or at the end of the body when index is omitted). The URL must be reachable by Google without auth, at most 50 MB and 25 megapixels, in PNG, JPEG or GIF; there is no upload channel — a local file must be hosted somewhere public first. width_pt/height_pt set the displayed size in points (omit both for natural size capped to the page width; when only one is given the API scales the other to keep the aspect ratio). Returns the created objectId in the reply — keep it for replace_image. Delete an image by deleting its range with delete_range (it occupies one index). It is categorised as a Write tool in the Mcp Google Docs MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does insert_image accept? +

insert_image accepts 7 parameters: uri, index, tab_id, width_pt, height_pt, segment_id, document_id. Required: uri, document_id. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on insert_image? +

Register the Mcp Google Docs MCP server in PolicyLayer and add a rule for insert_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 Docs. Nothing to install.

What risk level is insert_image? +

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

Can I rate-limit insert_image? +

Yes. Add a rate_limit block to the insert_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 insert_image completely? +

Set action: deny in the PolicyLayer policy for insert_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 insert_image? +

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