Everything between the microphone and the reply.
Core capabilities, one router. Compose them per agent, pair clients securely, and observe which provider actually served the turn.
Wake word + barge-in
An openWakeWord listener runs always-on. Say a wake word mid-reply and the whole playback process group is signaled instantly to start the new turn — barge-in is wake-gated, so it works without echo cancellation. Custom “hey dante”-style models train from synthetic speech alone in about 30 minutes — no recordings needed.
Streaming TTS
Audio starts the moment the provider emits its first chunk via /v1/tts/stream — no waiting for full synthesis.
Swappable providers
STT, LLM, and TTS are all pluggable. Cloud APIs or fully local servers — any OpenAI-compatible endpoint drops straight in.
OpenRouter sign-in
Authorize OpenRouter from the local Settings UI with a one-time PKCE flow. The hub keeps the verifier server-side, claims the issued key once, and never puts it in a URL or browser history.
A2A routing, per-agent voices
Route turns to OpenClaw / Hermes peers over A2A. Define peers by IP or let recommended setup migrate a compatible OpenClaw 2026.7.1-2 config, scan private networks, and verify locally stored credentials against gateways that publish a public card but protect conversations — then save the working agent without secret copying.
Provider health
See process-lifetime attempts, errors, 429s, fallback rescues, last use, and supported quota headers in the console or /v1/providers/stats.
MCP tool calling
LLM agents call tools over MCP servers automatically — up to 5 rounds per turn, speaking JSON-RPC 2.0 over streamable HTTP with session continuity. Unreachable servers are skipped, not fatal.
Per-agent memory, screened before replay
Each agent remembers its last N turns, optionally persisted to disk. OWASP Agent Memory Guard screens stored history for prompt-injection patterns and redacts token-like secrets before a later LLM fallback can replay that context.
Self-hosted, local-first, client-safe
The always-on pieces stay on your hardware. Docker Compose, Windows and macOS desktop hubs, local-CA HTTPS for paired LAN clients, and revocable phone/watch credentials instead of administrator-key copying.
