@azrtydxb/kryton-mcp

stdio MCP shim for Kryton. Bridges stdio JSON-RPC (used by Claude Desktop, Cline, Continue, and other older MCP hosts) to a Kryton server's HTTP MCP transport at <server>/api/mcp.

Usage

{
  "mcpServers": {
    "kryton": {
      "command": "npx",
      "args": ["-y", "@azrtydxb/kryton-mcp"],
      "env": {
        "KRYTON_URL": "https://kryton.ai",
        "KRYTON_TOKEN": "kryton_..."
      }
    }
  }
}

Environment

| Variable | Default | Notes | | -------------- | -------------------- | ------------------------------------------------------------------------ | | KRYTON_URL | https://kryton.ai | Base URL of the Kryton server. The shim POSTs to <url>/api/mcp. | | KRYTON_TOKEN | (required) | Bearer token, must begin with kryton_. Mint via kryton-init or UI. | | KRYTON_DEBUG | unset | When 1, emits [kryton-mcp] level=… msg=… … lines on stderr. |

Exit codes

| Code | Meaning | | ---- | --------------------------------------------- | | 0 | Clean shutdown (stdin closed). | | 1 | Missing/invalid env, or fatal upstream error. |

The shim is a thin proxy — the upstream Kryton server is the source of truth for the tool list, which is generated dynamically from its OpenAPI spec.
