## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `messageId` | string | yes |  |

Parameters from the server's own tool schema.

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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "read_message",
    "arguments": {
      "messageId": "<messageId>"
    }
  }
}
```

## Why read_message is rated Low

Marking a message as read is a benign read operation that retrieves or updates message state without creating financial obligations, executing code, or destructively removing data. Despite the financial context of the MIDAS Protocol server, this tool itself performs only a read/status-update action with minimal blast radius if misused by an AI agent.

From the tool's own definition: "Tool name 'read_message' and description 'Mark a message as read' indicate a message status operation with no data creation, modification, or deletion—only reading and marking."

## Use case

AI agents call read_message to retrieve information from MIDAS Protocol without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches MIDAS Protocol:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "read_message": {}
  }
}
```
