Pipecat vs Deepgram Voice Agent

   Pipecat provides a CLI (`pipecat init`, `pipecat cloud`, `pipecat context-hub`) and code-level telephony hooks (`python bot.py -t twilio -x ngrok...`) that let a coding agent scaffold and run a bot, and the context-hub can register an MCP server for coding-agent tooling, but there is no documented single API/CLI/MCP flow that creates the agent, provisions/attaches a phone number, and places a call — telephony setup still relies on the carrier's (Twilio/Telnyx) own console/API for number purchase and webhook config. missing for 10: a unified provisioning API or CLI command that attaches a phone number and places a call, MCP-driven agent creation (context-hub only builds a docs index, not agent provisioning), evidence of number attachment without touching a carrier dashboard.

   Deepgram documents agent creation via reusable agent configs (UUID-based), telephony connectivity for inbound/outbound calls, and a CLI with a built-in MCP server giving AI coding tools API access — the building blocks for programmatic provisioning exist. However, the evidence shows phone-call handling is done via a Twilio bridge (server code required) rather than a native Deepgram 'attach number/place call' API, and no doc shows the CLI or MCP server actually exposing agent-create + number-attach + call-place as a single end-to-end flow.
