No approval primitive or prompt-injection guidance was found.\n\n## Before you call either\n\n### Hume EVI (Empathic Voice Interface)\n\n1. Create a config with a voice first, EVI 3 has no default\n2. Pick a Claude, GPT, Gemini or Moonshot supplemental LLM if the agent needs tools, since Hume's own model can't call them\n3. Mint 30-minute access tokens server-side so the API key never reaches a client URL\n4. Turn on 'Do not retain data' and 'Do not use for training' at app.hume.ai before sensitive calls\n5. Reconnect with the chat group ID before the 30-minute session cap, and on E0700 close an open chat before starting another\n\n### LiveKit Agents\n\n1. Set `LIVEKIT_URL`, `LIVEKIT_API_KEY` and `LIVEKIT_API_SECRET` before starting. Every agent joins a LiveKit room, on LiveKit Cloud or a self-hosted server\n2. Pass `inference.TurnDetector(version=\"v1-mini\")` to keep turn detection local, and read `MODEL_LICENSE` before using LiveKit's turn models anywhere but LiveKit Agents\n3. Pass `record=False`, or a dict per category, to `session.start()` if audio, transcripts, traces and logs must not reach LiveKit Cloud\n4. Call `context.disallow_interruptions()` first in tools that write, and set `on_duplicate=\"reject\"` or `\"confirm\"`. Duplicates are matched by tool name only, not arguments\n5. Wrap MCP servers in `mcp.MCPToolset` with `allowed_tools` (Python only). The `mcp_servers` parameter is deprecated\n\n## Questions\n\n### Which is better for AI agents, Hume EVI (Empathic Voice Interface) or LiveKit Agents?\n\nLiveKit Agents scores 72.5 (BB) on agent readiness against Hume EVI (Empathic Voice Interface)'s 56.7 (C), and leads in 6 of 7 scored categories. Hume EVI (Empathic Voice Interface) leads on schema \u0026 documentation.\n\n### Can an agent call Hume EVI (Empathic Voice Interface) and LiveKit Agents without installing anything?\n\nHume EVI (Empathic Voice Interface) has a hosted endpoint at https://api.hume.ai/v0/evi. No hosted endpoint is listed for LiveKit Agents.\n\n### Are Hume EVI (Empathic Voice Interface) and LiveKit Agents open source?\n\nNo open-source release is listed for Hume EVI (Empathic Voice Interface).
