Apa Itu MCP?

terminal

AI Agent (OpenCode) ──MCP──► External Service (DB, API, Files)

Agent nggak perlu tahu detail API masing-masing. Cukup pakai MCP tools.

Kapan Butuh MCP?

| Butuh MCP | Nggak Butuh | |-----------|-------------| | Akses database (Postgres, MySQL) | Cuma baca/tulis file lokal | | Panggil API (GitHub, Slack, Notion) | Project sederhana offline | | Browser automation (scrape, test) | Belajar dasar agent | | File system remote (SSH, FTP) | Model gratis sudah cukup |

Contoh MCP Server Populer

| Server | Fungsi | |--------|--------| | filesystem | Baca/tulis file lokal | | github | Issue, PR, repo | | postgres | Query database | | sqlite | Database lokal | | fetch | HTTP request | | puppeteer | Browser automation |

Cara Tambah MCP ke OpenCode

Via OpenCode (mudah):

terminal

Tambah MCP server filesystem

Manual config:

json

{
  "mcp": {
    "filesystem": {
      "type": "local",
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-filesystem", "/path/folder"]
    },
    "github": {
      "type": "local",
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-github"],
      "env": { "GITHUB_PERSONAL_ACCESS_TOKEN": "your-token" }
    }
  }
}

⚠️ Risiko & Keamanan

MCP server = akses penuh ke resource kamu

Bisa baca semua file di folder yg diizinkan

Server remote bisa lihat data yg dikirim

Token di config = risiko kebocoran

Best practice:

Pakai MCP official/populer

Batasi folder akses (jangan root /)

Read-only mode kalau bisa

Audit config berkala

Hapus MCP yg nggak dipakai

Kapan Mulai Pakai MCP?

Setelah:

✅ Agent pertama jalan
✅ Paham cara OpenCode kerja
✅ Butuh integrasi yg nggak bisa manual

Belum perlu buru-buru. Fokus belajar dulu.
