Koma Gate MCP

Expose Koma Gate's prompt-injection classification as an MCP tool for AI agents. Provides a single tool, classify_input, that an AI agent can call to check whether untrusted user text is safe and in-scope before acting on it. It runs locally over stdio via the published package.

People who work with ai security, guardrails and middleware and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Koma Gate MCP

before you install - you'll need

Set KOMA_PROVIDER, GEMINI_API_KEY before connecting.

Claude Code

claude mcp add swnotmetal-project-koma-packages-koma-ga -- npx -y koma-gate-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "swnotmetal-project-koma-packages-koma-ga": {
      "command": "npx",
      "args": [
        "-y",
        "koma-gate-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.
