MCP Server

The dg CLI includes a built-in MCP (Model Context Protocol) server that gives AI coding tools direct access to Deepgram APIs.

Start the MCP Server

$
dg mcp

Starts a server using stdio transport (default).

HTTP/SSE Transport

For HTTP-based MCP clients:

$
dg mcp --transport sse --port 8000

5
      "command": "dg",
6
      "args": ["mcp"]

Available Tools

The MCP server exposes these capabilities:

• transcribe_audio — Transcribe audio from URL or file path
• synthesize_speech — Generate speech from text
• analyze_text — Sentiment, topics, summarization
• list_models — List available Deepgram models
• get_usage — Check API usage

Authentication

The MCP server uses your stored credentials (dg login) automatically.

For CI environments:

$
DEEPGRAM_API_KEY=sk_xxx dg mcp
