## Facts

- Tool: `send-message`
- Server: Frontmcp (`agentfront/frontmcp`) — https://policylayer.com/tools/frontmcp.md
- Homepage: https://github.com/agentfront/frontmcp
- Risk category: Write (Medium risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Rate-limited

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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "send-message",
    "arguments": {}
  }
}
```

## Why send-message is rated Medium

This tool creates new data (messages) in a reversible manner typical of Write operations. It is not Read (it modifies system state by sending), not Destructive (messages can be edited or deleted later), not Execute (it does not run arbitrary code—it invokes a specific business operation), and not Financial.

From the tool's own definition: "The tool 'send-message' explicitly describes sending a message that 'the recipient will receive it and may reply', indicating creation of new communication data in the system with potential side effects on recipient state and notification systems."

## Use case

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

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "send-message": {
      "limits": [
        {
          "counter": "send-message_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
```
