Replace content in an existing Quip document
AI agents use replace_content to create or update resources in Quip — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Quip environment.
This tool creates or modifies data reversibly within an existing document. While it changes document content, the action is reversible (previous versions can be restored, content can be replaced again), and it does not irreversibly delete data or destroy the document structure.
From the tool's definition Tool name 'replace_content' and description 'Replace content in an existing Quip document' indicate modification of existing document data.
Documented attack patterns abuse exactly the kind of access replace_content gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Quip, and nothing reaches the server without passing your rules. This is the rule we recommend for replace_content:
{
"version": "1",
"default": "deny",
"tools": {
"replace_content": {
"limits": [
{
"counter": "replace_content_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}replace_content 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.

Replace content in an existing Quip document. It is categorised as a Write tool in the Quip MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Quip MCP server in PolicyLayer and add a rule for replace_content: 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 Quip. Nothing to install.
replace_content 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 replace_content 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 replace_content. 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.
replace_content is provided by the Quip MCP server (petertilsen/quip-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Quip, 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.
