MCP Gateway & Registry

作者 agentic-community · agentic-community/mcp-gateway-registry

One HTTP endpoint that fronts every internal MCP server — central auth, per-team namespaces, audit log, and a web UI for discovery.

Instead of giving every developer a list of stdio configs, run this gateway once: it registers child MCP servers, brokers connections, enforces auth, and exposes a discovery UI. Developers point Claude at one URL.

      }
    }
  }
}

Claude Desktop → Settings → Developer → Edit Config を開く。保存後、アプリを再起動。

      }
    }
  }
}

Cursor は Claude Desktop と同じ mcpServers スキーマを使用。プロジェクト設定はグローバルより優先。

  "mcpServers": {
    "mcp-gateway-registry": {
      "command": "docker",
      "args": [
        "run",
        "-p",

      ],
      "env": {
        "GATEWAY_TOKEN": "${GATEWAY_TOKEN}"
      }
    }
  }
}

Cline サイドバーの MCP Servers アイコンをクリックし、"Edit Configuration" を選択。

~/.codeium/windsurf/mcp_config.json
{
  "mcpServers": {
    "mcp-gateway-registry": {
      "command": "docker",
      "args": [
        "run",
        "-p",
        "8080:8080",
        "-e",
        "GATEWAY_TOKEN",
        "ghcr.io/agentic-community/mcp-gateway-registry:latest"
      ],
      "env": {
        "GATEWAY_TOKEN": "${GATEWAY_TOKEN}"
      }
    }
  }
}

Claude Desktop と同じ形式。Windsurf を再起動して反映。

~/.continue/config.json
{
  "mcpServers": [
    {
      "name": "mcp-gateway-registry",
      "command": "docker",
      "args": [
        "run",
        "-p",
        "8080:8080",
        "-e",
        "GATEWAY_TOKEN",
        "ghcr.io/agentic-community/mcp-gateway-registry:latest"
      ]
    }
  ]
}

Continue はマップではなくサーバーオブジェクトの配列を使用。

~/.config/zed/settings.json
{
  "context_servers": {
    "mcp-gateway-registry": {
      "command": {
        "path": "docker",
        "args": [
          "run",
          "-p",
          "8080:8080",
          "-e",
          "GATEWAY_TOKEN",
          "ghcr.io/agentic-community/mcp-gateway-registry:latest"
        ]
      }
    }
  }
}

context_servers に追加。保存時に Zed がホットリロード。

claude mcp add mcp-gateway-registry -- docker run -p 8080:8080 -e GATEWAY_TOKEN ghcr.io/agentic-community/mcp-gateway-registry:latest

ワンライナー。claude mcp list で確認、claude mcp remove で削除。

ユースケース

実用的な使い方: MCP Gateway & Registry

Roll out MCP to a 200-person eng org

👤 Developers ⏱ ~15 min intermediate

使うタイミング: Different teams want different MCPs; you want central control without manual configs per dev.

フロー
  1. Deploy
    Stand up the gateway; wire it to your IdP.✓ コピーしました
    → Login works
  2. Register MCPs
    In the registry UI, add github, linear, sentry, internal-api MCPs with per-team scopes.✓ コピーしました
    → Servers visible
  3. Onboard
    Devs point Claude at https://mcp.corp/sse; gateway authorizes.✓ コピーしました
    → Devs use only what their team is allowed

結果: Centralized rollout with per-team scopes and one config to ship to clients.

Audit every MCP tool call across the org

👤 Developers ⏱ ~15 min intermediate

使うタイミング: Security needs an answer to "who called what tool when".

フロー
  1. Enable audit sink
    Configure gateway to ship logs to your SIEM.✓ コピーしました
    → Logs flowing
  2. Query
    Search for tool calls touching production resources in last 24h.✓ コピーしました
    → Per-user trail returned

結果: Complete audit trail of MCP usage org-wide.

セキュリティ

最小スコープ: gateway-admin gateway-user
認証情報の保管: OIDC tokens; child-server credentials in vault
データ送信先: Where each child MCP egresses
絶対に付与しない: expose gateway publicly without OIDC

トラブルシューティング

よくあるエラーと対処法

Tool list empty

Check the principal has scope for at least one registered server

Slow first call

Gateway lazy-starts child servers; pre-warm hot ones
