One account-wide key, sent in the WebSocket and Twilio webhook URLs. Hume ends API access on 13 November 2026.\n\n**Pipecat.** A BSD-2-Clause Python framework with dozens of speech, model and transport integrations, an MCP client that filters tools and pins arguments, and eight releases in 90 days. It has no tool-approval step, and 1.12.0 can send OPENAI_API_KEY to other OpenAI-compatible providers when no key is passed, a flaw fixed on main but not yet released.\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### Pipecat\n\n1. Pass `api_key` explicitly to every OpenAI-compatible service such as Groq, Cerebras or OpenRouter. On 1.12.0 a missing key sends `OPENAI_API_KEY` to that provider\n2. Pass `tools_filter` to `MCPClient` so only the tools the call needs reach the model, and use `tools_arguments` for values the model must not choose\n3. Gate tools that book, pay or send in your own handler. Pipecat has no approval step, and a caller's speech goes straight to the model\n4. Keep the development runner on localhost. Its `/start`, `/daily` and dial-in webhook endpoints take requests from anyone by design\n5. Pin a minor version and read the breaking-change flags in CHANGELOG.md before upgrading, since minor releases remove and rename APIs\n\n## Questions\n\n### Which is better for AI agents, Hume EVI (Empathic Voice Interface) or Pipecat?\n\nPipecat scores 68.9 (B) on agent readiness against Hume EVI (Empathic Voice Interface)'s 56.7 (C), and leads in 6 of 7 scored categories.\n\n### Can an agent call Hume EVI (Empathic Voice Interface) and Pipecat 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 Pipecat.\n\n### Are Hume EVI (Empathic Voice Interface) and Pipecat open source?\n\nNo open-source release is listed for Hume EVI (Empathic Voice Interface).
