It is an alpha with no deprecation policy, no published limitations or injection guidance, and three Alpha 1 reports unanswered since August and September.\n\n**Vapi API + MCP.** Voice agents can combine supported transcription, model and voice providers, including customer-supplied endpoints. Per-minute cost depends on the selected providers.\n\n## Before you call either\n\n### Pipecat PhoneLLM\n\n1. Send `temperature: 0` on every call. The repositories' generation_config.json samples by default, and Max's sets temperature 1.0\n2. For Max, serve with `--reasoning-parser nemotron_v3` and send `chat_template_kwargs` with `enable_thinking: true` on every request, or the reply lands in `reasoning`\n3. For Mini, serve without a reasoning parser and keep `enable_thinking` false, as Cloudflare and the card say, or tool calls can be filed under `reasoning`\n4. Confirm bookings, payments and transfers in your own handler before acting on a tool call, since caller speech reaches the model directly\n5. Pin the model ID including `alpha-2`. Daily states no notice period, and a later alpha may replace it\n\n### Vapi API + MCP\n\n1. Read `subscriptionLimits.concurrencyBlocked` in the `POST /call` response, a full account queues the call rather than failing\n2. Confirm with a person before `vapi_create_call` or `vapi_buy_phone_number`, the server won't ask\n3. Pin transcriber, model and voice and set fallback plans so one provider outage doesn't drop calls\n4. Read the call log's cost breakdown to see what each provider charged\n5. Check `@vapi-ai/server-sdk` isn't pinned to 0.11.1, 0.11.2, 1.2.1 or 1.2.2\n\n## Questions\n\n### Which is better for AI agents, Pipecat PhoneLLM or Vapi API + MCP?\n\nVapi API + MCP scores 63.5 (B) on agent readiness against Pipecat PhoneLLM's 58.7 (C), and leads in 5 of 7 scored categories. Pipecat PhoneLLM leads on security \u0026 auth and payments \u0026 pricing.\n\n### Do Pipecat PhoneLLM and Vapi API + MCP need an API key?\n\nBoth need an API key.\n\n### Can an agent call Pipecat PhoneLLM and Vapi API + MCP without installing anything?\n\nYes.
