@opsmaxx/mcp

Connect any stdio MCP client to a running OpsMaxx desktop app.

npx -y @opsmaxx/mcp

Why this exists

OpsMaxx already exposes an MCP server over Streamable HTTP on 127.0.0.1, and clients that can express an HTTP server with an Authorization header — Claude Code, Codex — should use that directly. It is one command:

opsmaxx claude

Some clients cannot. Claude Desktop, notably, does not read url or headers from claude_desktop_config.json at all, so an HTTP MCP server is simply not expressible there. This package is the adapter for those: stdio in, authenticated HTTP out.

What it does, and does not

It is a protocol relay. Every message is forwarded unmodified in both directions. No tool, session or policy logic lives here — access groups, approvals, secret redaction and the audit log all stay in the app, so a stdio client gets exactly the same treatment an HTTP client would.

It talks only to 127.0.0.1. It is not a server, it holds no state, and it cannot reach anything OpsMaxx would not already allow.

OpsMaxx must be running, with the bridge enabled under AI & MCP.

Configuration

Environment first, then the session the opsmaxx CLI has already cached:

If none are set it reads the session cached by the CLI, so running opsmaxx claude once is enough and there is no token to paste.

Claude Desktop

{
  "mcpServers": {
    "opsmaxx": {
      "command": "npx",
      "args": ["-y", "@opsmaxx/mcp"],
      "env": {
        "OPSMAXX_MCP_TOKEN": "your-session-token",
        "OPSMAXX_MCP_PORT": "5177"
      }
    }
  }
}

Restart Claude Desktop afterwards.

A note on the token

The token is scoped to one workspace and one access group, and it is the same secret you would otherwise paste into a client's config by hand. It is not an SSH key and it is not a vault password: an agent holding it still never receives an SSH password, a private key, a database credential, a hostname or an interactive root shell.
