Insert text at a specific paragraph index (preserves formatting on other paragraphs)
AI agents use pages_insert_text_at to create or update resources in Iwork — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Iwork environment.
This tool inserts text into a Pages document at a specified location, which is a reversible modification operation. It does not execute arbitrary code, delete content irreversibly, or involve financial transactions. While it modifies a document, the action is reversible (text can be deleted or edited later).
From the tool's definition Tool name 'pages_insert_text_at' and description 'Insert text at a specific paragraph index' indicate the tool creates or modifies document content.

PolicyLayer is an MCP gateway — it sits between your AI agents and Iwork, and nothing reaches the server without passing your rules. This is the rule we recommend for pages_insert_text_at:
{
"version": "1",
"default": "deny",
"tools": {
"pages_insert_text_at": {
"limits": [
{
"counter": "pages_insert_text_at_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}pages_insert_text_at 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.

Insert text at a specific paragraph index (preserves formatting on other paragraphs). It is categorised as a Write tool in the Iwork MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Iwork MCP server in PolicyLayer and add a rule for pages_insert_text_at: 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 Iwork. Nothing to install.
pages_insert_text_at 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 pages_insert_text_at 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 pages_insert_text_at. 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.
pages_insert_text_at is provided by the Iwork MCP server (reichenbach/iwork_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Iwork, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
