Find and replace text in a Pages document.
AI agents use pages.find_replace to create or update resources in Orchard — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Orchard environment.
This tool creates or modifies data reversibly (the core definition of Write). Find-and-replace changes document content but the operation is reversible via undo. It does not delete documents (would be Destructive) nor execute arbitrary code (would be Execute).
From the tool's definition "Find and replace text in a Pages document" - modifies document content; Pages is Apple's word processor where find-and-replace operations alter the document state.
Documented attack patterns abuse exactly the kind of access pages.find_replace gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Orchard, and nothing reaches the server without passing your rules. This is the rule we recommend for pages.find_replace:
{
"version": "1",
"default": "deny",
"tools": {
"pages.find_replace": {
"limits": [
{
"counter": "pages.find_replace_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}pages.find_replace 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.

Find and replace text in a Pages document. It is categorised as a Write tool in the Orchard MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Orchard MCP server in PolicyLayer and add a rule for pages.find_replace: 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 Orchard. Nothing to install.
pages.find_replace 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.find_replace 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.find_replace. 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.find_replace is provided by the Orchard MCP server (l22-io/orchard-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Orchard, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
