Home Assistant with Home MCP in Hermes Agent

Hombee Free

Configure the remote server

Hermes Agent reads MCP servers from ~/.hermes/config.yaml. Add Home MCP as a remote HTTP server and use the client’s OAuth flow instead of a static token.

mcp_servers:
  hombee:
    url: https://your-public-home-mcp-url/mcp
    auth: oauth
  1. Save the configuration and restart Hermes Agent.
  2. Run hermes mcp login hombee.
  3. Complete Hombee authorization in the browser.
  4. Review the tool list. Use Hermes tool filtering to expose only the Home MCP capabilities needed for the task.

On a remote or headless host, follow Hermes’ documented paste-back or SSH forwarding flow. Treat the returned authorization URL and redirect address as sensitive. Never paste a browser session or refresh token into the YAML file.

Verify Home Assistant from Hermes Agent

Ask: “Use hombee to list the Home Assistant areas available to me and explain which tools are read-only. Do not change state.” Keep approval enabled for any operation that controls a device, changes security, runs an automation or sends data outside the installation.

If hermes mcp login does not recognize the server, check YAML indentation and the configured name. If authentication works but discovery is empty, restart the agent and verify the Hombee user and installation. A narrower tool set can be correct: Home MCP matches tools to the account, modules and available capabilities.
