THE RISK

Medium Risk

Why enhance_text needs a policy

This tool takes existing text and produces an expanded or enriched version, which is a reversible write/transformation operation. It does not execute code, delete data, or involve financial transactions. The severity is medium because an AI agent could misuse it to alter content in unintended ways, but the blast radius is limited to text modification.

From the tool's definition 'Expands text using all five enhancement techniques' — creates modified/enriched content from input text

POLICY

How to control enhance_text

PolicyLayer is an MCP gateway — it sits between your AI agents and UNO-MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for enhance_text:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "enhance_text": {
      "limits": [
        {
          "counter": "enhance_text_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

enhance_text 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 free account and register UNO-MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about enhance_text

What does the enhance_text tool do? +

Expands text using all five enhancement techniques. It is categorised as a Write tool in the UNO-MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on enhance_text? +

Register the UNO- MCP server in PolicyLayer and add a rule for enhance_text: 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 UNO-MCP. Nothing to install.

What risk level is enhance_text? +

enhance_text is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit enhance_text? +

Yes. Add a rate_limit block to the enhance_text 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.

How do I block enhance_text completely? +

Set action: deny in the PolicyLayer policy for enhance_text. 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.

What MCP server provides enhance_text? +

enhance_text is provided by the UNO- MCP server (mushroomfleet/uno-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every UNO-MCP tool call.

Start from UNO-MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
