Update or append to an existing AI-generated document (requires API key)
AI agents use pluggedin_update_document to create or update resources in Pluggedin Mcp Proxy — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Pluggedin Mcp Proxy environment.
This tool creates or modifies data (document content) in a reversible manner, fitting the Write category. Severity is high because an AI agent could modify important documents without authorization, potentially affecting business-critical content, though the impact is limited by the document scope (not system-wide destructive changes).
From the tool's definition Tool description states it will 'Update or append to an existing AI-generated document'. Update and append are reversible write operations that modify existing data.

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