feat: add Hermes ACP driver support - #53
Conversation
- Add Hermes ACP driver (server/drivers/acp/hermes.ts) - Register HermesDriver in builtIn.ts - Add hermes instance to default fleet in config.ts - Bind harness to 0.0.0.0:8799 and Vite to 0.0.0.0:5199 for Netbird access - Downgrade Node engine requirement >=24 to >=22 for server compat Verified end-to-end: a Hermes bot spawned hermes-acp and replied through the harness on the Netbird IP.

📝 WalkthroughWalkthroughThe change adds and registers the Hermes ACP driver, enables it in the default instance configuration, lowers the minimum Node.js version to 22, and binds the server and Vite development server to all network interfaces. ChangesHermes ACP support
Network binding and runtime compatibility
Estimated code review effort: 2 (Simple) | ~10 minutes Mergeability Score: 🟡 Moderate · up to The PR adds Hermes ACP support and broadens the supported Node.js range, but the current implementation may continue authentication without required credentials and may allow unsupported Node.js versions for the Vite toolchain. These bounded correctness and compatibility risks should be addressed or explicitly accepted before merging. Sequence Diagram(s)sequenceDiagram

- Line 8: Update the Node.js version constraint in the package engines
configuration from >=22 to >=22.12.0, ensuring the declared runtime floor
matches the Vite requirement.
In `@server/drivers/acp/hermes.ts`:
- Line 2: The Hermes AcpSupport configuration must exclude the hermes-setup
method when selecting authentication methods. Update pickAuthMethod to choose
only provider methods, return null when none remain, and change authFailure to
"fail" so the shared driver skips authentication and stops with loginNote.
In `@server/index.ts`:
- Line 818: Update the startup log in the server initialization flow to avoid
hard-coding the Netbird address; derive the advertised host from the runtime
configuration, or omit the Netbird URL and log only the bind state and PORT.
- Around line 817-818: Restrict both server listeners to the Netbird interface
instead of binding publicly to 0.0.0.0; update the server.listen call in
server/index.ts and the corresponding Vite server configuration in
vite.config.ts (lines 24-26). Preserve the existing ports and startup behavior
while ensuring both services are reachable only through the Netbird address.

NousResearch hermes-agent ACP auth.py hermes-setup authenticate provider credentials
💡 Result:
In the NousResearch Hermes Agent, authentication is managed through a centralized runtime resolver system rather than directly within the Agent Protocol (ACP) adapter [1]. The acp_adapter/auth.py module acts as a bridge, utilizing the agent's pre-configured runtime provider credentials [2][1][3]. Key mechanisms for authentication and provider setup include: 1. Provider Detection and Advertising: The ACP server uses detect_provider() (defined in acp_adapter/auth.py) to identify active LLM runtime credentials [3]. During the initial ACP handshake, the server advertises these configured auth methods to the client [1][3]. If no credentials have been configured, it advertises a terminal setup method (ID: TERMINAL_SETUP_AUTH_METHOD_ID) which prompts the client to trigger an interactive setup flow, such as hermes setup --setup [2][1][3]. 2. Credential Management: Hermes uses hermes_cli/auth.py to handle diverse authentication types, including OAuth (e.g., Nous Portal, Qwen, Google Gemini) and traditional API keys (e.g., OpenRouter, Anthropic, Copilot) [4][5][6]. Credential state is stored securely in ~/.hermes/auth.json (for OAuth/tokens) or ~/.hermes/.env (for environment-based API keys), kept separate from general configuration in config.yaml [7][8][9]. 3. Setup and Authentication Flows: - Automated Setup: The recommended method is hermes setup --portal, which initiates the Nous Portal OAuth flow, handles credential storage, and configures the provider and gateway in a single command [7][8][10]. - Interactive Setup: Users can run hermes setup to invoke a wizard that walks through selecting providers, entering credentials, and verifying connectivity [10]. - Manual Configuration: Users can manage providers and credentials via subcommands such as hermes auth add <provider> or hermes model [7][11]. The hermes doctor command is available to validate configuration, syntax, and connectivity [12][10]. The ACP adapter does not implement its own authentication store, ensuring that it remains synchronized with the primary Hermes CLI credential resolution logic [1][3].

Restrict both listeners to the Netbird interface or authenticate the API. Port 8799 and port 5199 bind to 0.0.0.0. Authentication protects only /api/internal/*; public routes allow bot control, configuration writes, connector actions, and Box command execution. Bind both services to the Netbird address or enforce firewall rules that allow only Netbird traffic. Otherwise, add authentication before exposing either port.

Do not bind the unauthenticated harness and Vite server to 0.0.0.0: the public API includes config writes, bot control, connector actions, and Box commands. Please keep both listeners loopback-only and remove the unrelated Node engine downgrade; then add focused Hermes ACP auth/contract tests for the driver itself.

Closing this because it is no longer a safe or current integration path. Alongside the three-line Hermes driver, this branch changes the app and Vite servers from loopback-only to |
