# /security mcp-inspect [path]
|
|
|
|
Live MCP runtime inspection — connects to each configured MCP stdio server via JSON-RPC 2.0, fetches tool/prompt/resource lists, and scans descriptions for injection patterns and tool shadowing.
|
|
|
|
## Step 1: Run Scanner
|
|
|
|
Determine plugin root (parent of this `commands/` folder) and target path from `$ARGUMENTS` (default `.`).
|
|
|
|
```bash
|
|
node <plugin-root>/scanners/mcp-live-inspect.mjs "<target>"
|
|
```
|
|
|
|
Parse stdout as JSON. If exit code is non-zero and no JSON output, show the error and STOP.
|
|
|
|
## Step 2: Report

## MCP Live Inspection: <VERDICT>

For each finding (sorted critical → info):
|
|
|
|
```
|
|
### Findings (<count>)
|
|
|
|
| # | Severity | Title | OWASP | Recommendation |
|
|
```
|
|
|
|
If zero findings: "No injection, shadowing, or drift detected across N servers."
|
|
|
|
## Step 3: Advisory
|
|
|
|
- If `servers_timed_out > 0`: "N servers timed out (10s). Ensure they can start independently — check command, env vars, and args."
|
|
- If `servers_skipped_sse > 0`: "N SSE servers skipped — live inspection requires stdio transport."
|
|
- If `servers_failed > 0`: "N servers failed to start. Verify the command path exists and is executable."
|
|
- If `servers_discovered == 0`: "No MCP servers found in config locations. Check .mcp.json, .claude/settings.json, or ~/.claude/settings.json."
|
|
|
|
## Step 4: Combined Use
|
|
|
|
Mention: "For combined static + live analysis, use `/security mcp-audit --live`."
