Test AI inference through your node.

Use your personal MCP configuration

Open ~/.cursor/mcp.json on macOS/Linux, or %USERPROFILE%\.cursor\mcp.json on Windows. Merge this server into mcpServers if the file already contains other servers.

{
  "mcpServers": {
    "eiou-passthrough": {
      "url": "https://YOUR-NODE/p/mcp-passthrough/mcp",
      "headers": {
        "Authorization": "Bearer mcp_REPLACE_WITH_YOUR_NODE_KEY"
      }
    }
  }
}

Replace the URL and bearer key, save, and enable the server in Cursor’s MCP settings. Reload Cursor if it does not appear. A project’s .cursor/mcp.json is also supported, but a personal config avoids putting a live key into the project.

Confirm that chat.list_models and balance.check are available before making a billed call.

Launch an authenticated HTTP bridge

Install Node.js 18 or newer with npm, then open Settings → Developer → Edit Config. On macOS the file is ~/Library/Application Support/Claude/claude_desktop_config.json; on Windows it is %APPDATA%\Claude\claude_desktop_config.json.

{
  "mcpServers": {
    "eiou-passthrough": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote@0.14.3",
        "https://YOUR-NODE/p/mcp-passthrough/mcp",
        "--transport",
        "http-only",
        "--header",
        "Authorization:${EIOU_AUTH_HEADER}"
      ],
      "env": {
        "EIOU_AUTH_HEADER": "Bearer mcp_REPLACE_WITH_YOUR_NODE_KEY"
      }
    }
  }
}

Merge the entry into your existing mcpServers, replace the URL and key, then fully quit and restart Claude Desktop. The pinned mcp-remote bridge translates local stdio to Streamable HTTP and adds the bearer header. Leave the header variable reference in args unchanged; put your key in env. If Desktop cannot find npx, set command to its absolute installed path.

Check for the eIOU tools, list models and check the balance before trying a small paid completion.

Desktop’s Settings → Connectors remote connection runs from Anthropic’s cloud. It cannot reach your localhost or private node merely because your computer can. This plugin uses a static bearer key; use the local bridge recipe above rather than pasting this endpoint into the remote connector flow.

Add the endpoint from your terminal

claude mcp add --transport http \
  eiou-passthrough \
  https://<your-eiou-host>/p/mcp-passthrough/mcp \
  --header "Authorization: Bearer mcp_<CUSTOMER_API_KEY>"
claude mcp get eiou-passthrough

Replace the placeholders and keep the live key out of saved shell history.

Treat each bearer key as a password. These examples store keys in personal configuration; an env entry is not encrypted storage. Restrict access to the file, never commit it, and revoke a key if it leaks.

Use HTTPS for a remote node. Direct .onion access needs a separately configured Tor-capable connection; these client recipes do not configure Tor for you.
