@open-mcp/autobahn

Installing

First set the environment variables as shell variables:

# No environment variables required for this server

Then use the OpenMCP config CLI to add the server to your MCP client:

Claude desktop

npx @open-mcp/config add autobahn \
  ~/Library/Application\ Support/Claude/claude_desktop_config.json

Cursor

Run this from the root of your project directory or, to add to all cursor projects, run it from your home directory ~.

npx @open-mcp/config add autobahn \
  .cursor/mcp.json

Other

npx @open-mcp/config add autobahn \
  /path/to/client/config.json

Manually

If you don't want to use the helper above, add the following to your MCP client config manually:

{
  "mcpServers": {
    "autobahn": {
      "command": "npx",
      "args": ["-y", "@open-mcp/autobahn"],
      "env": {}
    }
  }
}

Customizing the base URL

Set the environment variable OPEN_MCP_BASE_URL to override each tool's base URL. This is useful if your OpenAPI spec defines a relative server URL.
