What insert_text does on Mcp Google Docs
AI agents use insert_text 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 |
|---|---|---|---|
text | string | Yes | The text to insert; \n starts a new paragraph. |
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. |
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.
Why insert_text is rated Medium
An AI agent can call insert_text 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.

The rule that runs insert_text 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_text, this is the rule to start with:
insert_text 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Mcp Google Docs, apply this rule, and every insert_text call is checked against it from then on.
Questions about insert_text
Inserts plain text at an index (UTF-16 code units; body content starts at index 1 — get indexes from read_document_text). Omit index to append at the end of the body (or of the segment when segment_id is set). Newlines in the text create new paragraphs; the text inherits the style at the insertion point — style it afterwards with style_text/style_paragraph. Every insert shifts all later indexes, so when making several edits, apply them from the END of the document backwards or re-read between edits. Returns the batchUpdate reply with the new revisionId. 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.
insert_text accepts 5 parameters: text, index, tab_id, segment_id, document_id. Required: text, document_id. The full parameter table on this page comes from the server's own tool schema.
Register the Mcp Google Docs MCP server in PolicyLayer and add a rule for insert_text: 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.
insert_text is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the insert_text 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.
Set action: deny in the PolicyLayer policy for insert_text. 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.
insert_text 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.
