## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",

  "params": {

## Why mark_message_read is rated Medium

This tool modifies email message properties (read/unread status) reversibly without deleting data or executing arbitrary operations. The change is non-destructive and easily undone by toggling the state back. While it affects user data, the blast radius is minimal—an agent could at most alter the read status of emails, which is a common, low-impact write operation.

From the tool's own definition: "Tool name 'mark_message_read' and description 'Mark an email message as read or unread' indicates modification of message metadata state."

## Use case

AI agents use mark_message_read to create or update resources in Iconnect, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Iconnect environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Iconnect:

```json
