WHAT IT DOES

What rewrite_text does on AirMCP

AI agents invoke rewrite_text to trigger actions in AirMCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why rewrite_text is rated High

This tool executes an on-device AI model to transform/rewrite provided text. It is not a simple data read (it produces new content), nor does it persistently write to a data store by itself — it runs a local inference operation and returns transformed output. The most accurate category is Execute, as it triggers an external computational process (Foundation Model inference).

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs rewrite_text safely

PolicyLayer is an MCP gateway: it sits between your AI agents and AirMCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For rewrite_text, this is the rule to start with:

rewrite_text Rate-limited

rewrite_text stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

The button opens the PolicyLayer dashboard: create your workspace, connect AirMCP, apply this rule, and every rewrite_text call is checked against it from then on.

FAQ

Questions about rewrite_text

What does the rewrite_text tool do? +

Rewrite text in a specified tone using Apple Intelligence (on-device Foundation Models). Requires macOS 26+ with Apple Silicon. It is categorised as a Execute tool in the AirMCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on rewrite_text? +

Register the Air MCP server in PolicyLayer and add a rule for rewrite_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 AirMCP. Nothing to install.

What risk level is rewrite_text? +

rewrite_text is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit rewrite_text? +

Yes. Add a rate_limit block to the rewrite_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 rewrite_text completely? +

Set action: deny in the PolicyLayer policy for rewrite_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 rewrite_text? +

rewrite_text is provided by the Air MCP server (airmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
