Speech recognition and voice-agent APIs. Flux adds model-integrated end-of-turn detection for voice agents; Nova covers conventional streaming and batch transcription.

Best for
  • Developers building dictation, transcription or voice agents
  • Low-latency streaming speech-to-text
Not for
  • Non-developers who want a finished transcription app

Top use cases

  • Stream live speech-to-text over a WebSocket source ↗
  • Detect when a speaker has finished a turn (Flux) to drive voice agents source ↗
  • Bias recognition toward names and jargon with keyterm prompting source ↗
  • Run a managed voice agent (listen, think, speak) over one connection source ↗
  • Give Claude Code or Cursor access to Deepgram APIs through the CLI's MCP server source ↗

MCP

The dg CLI includes an MCP server (stdio by default, or HTTP/SSE) that proxies Deepgram developer API tools to Claude Code, Cursor and Windsurf, using your stored login or an API key. A separate docs MCP server answers questions about Deepgram's documentation. source ↗

How to use it with AI

How Deepgram connects to each AI platform: native connector or MCP, API through code the agent writes, browser control, or file upload.

PlatformMCP / connectorAPI (agent-written code)BrowserUpload / export
Claude (incl. Claude Code) Not documented Deepgram has an official MCP server and Claude (incl. Claude Code) supports MCP, but Deepgram's docs don't name this pairing. Auth setup may differ. Deepgram MCP docs ↗Claude (incl. Claude Code) MCP docs ↗ Confirmed Claude (incl. Claude Code) can run code; Deepgram publishes an API. Deepgram API ↗Claude (incl.

OpenAI Codex Not documented Deepgram has an official MCP server and OpenAI Codex supports MCP, but Deepgram's docs don't name this pairing. Auth setup may differ.

Google Antigravity Not documented Deepgram has an official MCP server and Google Antigravity supports MCP, but Deepgram's docs don't name this pairing. Auth setup may differ.

Confirmed means both the tool's and the platform's official docs describe that route (links in the cell); IonBin has not tested every pairing. Not documented means it may work, but no official docs describe that route end to end. Checked Oct 17, 2026.
