Create a new tag for labeling and organizing documents. Tags can have colors for visual identification and automatic matching rules for smart assignment.
AI agents use create_tag to create or update resources in Paperless-NGX MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Paperless-NGX MCP Server environment.
This tool creates new metadata (tags) in the Paperless-NGX system. Creation is reversible (tags can be deleted, as evidenced by the sibling tool 'delete_tag'), making it a Write operation rather than Destructive.
From the tool's definition Tool creates new tags for document organization, with color and rule assignment capabilities. Description explicitly states 'Create a new tag' indicating reversible data creation.
Documented attack patterns abuse exactly the kind of access create_tag gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Paperless-NGX MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create_tag:
{
"version": "1",
"default": "deny",
"tools": {
"create_tag": {
"limits": [
{
"counter": "create_tag_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_tag 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.

Create a new tag for labeling and organizing documents. Tags can have colors for visual identification and automatic matching rules for smart assignment. It is categorised as a Write tool in the Paperless-NGX MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Paperless-NGX MCP Server MCP server in PolicyLayer and add a rule for create_tag: 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 Paperless-NGX MCP Server. Nothing to install.
create_tag 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 create_tag 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 create_tag. 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.
create_tag is provided by the Paperless-NGX MCP Server MCP server (nloui/paperless-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
