[RED TEAM] MCP server missing tools for 4 new commands (arch-metrics, memory, export-snapshot, import-snapshot) — CLI/MCP count drift 67 vs 50

[Wolfvin]

Temuan

Setelah merge #107, #109, #110, CLI command count naik ke 67, tapi MCP server hanya expose 50 tools. 4 command baru TIDAK terdaftar sebagai MCP tools:

• arch-metrics (feat(arch): add arch-metrics command — fan-in/out, instability, god-module detection (closes #61) #109) — tidak ada di MCP
• memory write/read/list/delete (feat(memory): Serena-style markdown memory system + CLI (closes #60 phase-1) #110) — tidak ada di MCP
• export-snapshot (feat(snapshot): export-snapshot + import-snapshot — share CodeLens graph across team (closes #12) #107) — tidak ada di MCP
• import-snapshot (feat(snapshot): export-snapshot + import-snapshot — share CodeLens graph across team (closes #12) #107) — tidak ada di MCP

AI agents yang akses CodeLens via MCP (e.g. Claude Desktop, Cursor) tidak bisa menggunakan fitur-fitur baru ini. Ini melanggar principle dari issue #90 ("single-source-of-truth for command + MCP tool counts").

Cara reproduce

import sys
sys.path.insert(0, 'scripts')
import mcp_server
tools = mcp_server._TOOL_DEFINITIONS
print(f'Total MCP tools: {len(tools)}')  # Output: 50

# Check for new commands
cli_commands = ['arch-metrics', 'memory', 'export-snapshot', 'import-snapshot']
for cmd in cli_commands:
    found = any(cmd in str(t) for t in tools)
    print(f'  {cmd}: {"FOUND" if found else "MISSING"}')

# CLI count
python scripts/codelens.py --command-count
# Output: 67

Output aktual

Total MCP tools: 50
  arch-metrics: MISSING
  memory: MISSING
  export-snapshot: MISSING
  import-snapshot: MISSING

CLI count: 67
MCP count: 50
Drift: 17 commands not exposed via MCP

Output yang diharapkan

MCP server harus expose minimal 4 command baru sebagai tools (arch-metrics, memory, export-snapshot, import-snapshot). Idealnya MCP tool count should track CLI command count (principle dari issue #90).

Severity

MEDIUM — AI agents via MCP cannot access new features. Bukan crash atau data loss, tapi fitur gap yang mengurangi value dari 8 PRs untuk MCP users. PR #110 description mention "memory system + CLI" — CLI-only memang by design phase-1, tapi tetap perlu MCP exposure agar konsisten dengan principle #90.

PR terkait

#107 (snapshot export/import), #109 (arch-metrics), #110 (memory system). Fix: tambahkan 4 tool definitions di scripts/mcp_server.py _TOOL_DEFINITIONS yang delegate ke command handlers yang sudah ada.
