THE RISK

Why send-image needs a policy

This tool creates and sends new message content (image attachments) to iMessage recipients, which is reversible but impactful communication. It is not Read (no retrieval), Execute (not running arbitrary code), Destructive (not irreversible), Financial (no money involved), or Other.

From the tool's definition Tool name 'send-image' with description 'Send an image to a recipient' indicates creation and transmission of message data through iMessage. The server description confirms it supports 'sending iMessages directly' and 'attachments'.

POLICY

How to control send-image

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "send-image": {
      "limits": [
        {
          "counter": "send-image_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

send-image 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 iMessage MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

How do I enforce a policy on send-image? +

Register the iMessage MCP Server MCP server in PolicyLayer and add a rule for send-image: 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 iMessage MCP Server. Nothing to install.

What risk level is send-image? +

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

Can I rate-limit send-image? +

Yes. Add a rate_limit block to the send-image 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 send-image completely? +

Set action: deny in the PolicyLayer policy for send-image. 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 send-image? +

send-image is provided by the iMessage MCP Server MCP server (sameelarif/imessage-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every iMessage MCP Server tool call.

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