## Facts

- Tool: `mcp_status`
- Server: Openhab (`deswong/openhab-mcp`) — https://policylayer.com/tools/deswong-openhab-mcp.md
- Homepage: https://github.com/deswong/Openhab-MCP
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Allowed

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

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

## Why mcp_status is rated Low

This tool only retrieves metadata about the MCP server itself and the home automation system state for AI context. It does not modify data, execute commands, delete anything, or involve financial operations. The 'health' metrics and capabilities inspection are read-only diagnostic operations with minimal blast radius.

From the tool's own definition: "Tool provides 'MCP server metadata' including 'health', 'capabilities', and 'prompt_context' — all informational queries with no side effects or state modification."

## Use case

AI agents call mcp_status to retrieve information from Openhab 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 Openhab:

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