## Which one, for what

### Bland AI API + MCP (B)

Good for: Teams that want one predictable per-minute bill for outbound and inbound phone agents, and personal agents that need their own US number.

Ahead on:
- Security & auth, 66 against 57
- Payments & pricing, 65 against 60

Also in its favour:
- A hosted endpoint, with nothing to install
- Runs on your own machine
- No incidents deducted, where Pipecat loses 4 points for them

Watch for: No OpenAPI document

### Pipecat (B)

Good for: Python teams that want to own a voice agent's pipeline, pick each speech and model provider, and host it themselves or on Pipecat Cloud.

Ahead on:
- Reliability, 72 against 65
- Schema & documentation, 90 against 68
- Agent ergonomics, 72 against 53
- Maintenance & community, 87 against 60
- Transparency & trust, 81 against 71

Also in its favour:
- No key needed to call it
- Open source

Watch for: No tool-approval or confirmation step, and no prompt-injection guidance, for tools that act on a caller's speech

## Verdicts

**Bland AI API + MCP.** One per-minute rate covering STT, LLM, TTS and telephony, $0.14 on Start and $0.12 on Build. No OpenAPI document.

**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.

## Before you call either

### Bland AI API + MCP

1. Call `wait_for_call` (it waits up to 45 seconds) instead of polling `get_call_log`
2. Send destructive MCP tools a second time with the confirmation argument
3. Space calls to the same number at least 10 seconds apart or expect a 429
4. Budget $0.015 for every outbound attempt, including ones that never connect
5. Run `validate_pathway` before saving a pathway graph

### Pipecat

1. 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
2. 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
3. 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
4. Keep the development runner on localhost. Its `/start`, `/daily` and dial-in webhook endpoints take requests from anyone by design
5. Pin a minor version and read the breaking-change flags in CHANGELOG.md before upgrading, since minor releases remove and rename APIs
