Bring Speech To Text
to LlamaIndex
Learn how to connect Deepgram to LlamaIndex and start using 6 AI agent tools in minutes. Fully managed, enterprise secure, and ready to use without writing a single line of code.
What is the Deepgram MCP Server?
Connect your Deepgram account to any AI agent and take full control of your speech-to-text (STT) and text-to-speech (TTS) workflows through natural conversation.
What you can do
- Transcription Orchestration — Convert speech from public audio or video URLs into high-fidelity text programmatically using the latest Nova-3 models with smart formatting and diarization
- Neural Speech Synthesis — Programmatically generate natural-sounding audio from text input using the high-speed Aura engine to coordinate voice-enabled interfaces
- Model Discovery — Access complete directories of high-performance STT and TTS models supported by Deepgram to ensure the perfect accuracy and latency for your content
- Project & Usage Monitoring — Programmatically track your API utilization, minute consumption, and request counts across multiple projects for instant operational reporting
- Credential Lifecycle — Retrieve identifiers for active API keys associated with your projects directly through your agent to maintain high-fidelity security oversight
How it works
1. Subscribe to this server
2. Retrieve your API Key from the Deepgram Console
3. Start transcribing and synthesizing audio from Claude, Cursor, or any MCP client
No more manual file uploading or complex latency tuning in the portal. Your AI acts as your dedicated audio engineer and media production coordinator.
Who is this for?
- Developers & Engineers — instantly transcribe recorded meetings and integrate high-speed TTS into applications using natural language commands
- Content Creators — automate the generation of voiceovers and subtitles for global video assets without leaving your workspace
- Research Teams — scale the processing of interview recordings and monitor usage limits through simple AI queries

Why teams choose Vinkius for Deepgram in LlamaIndex
The Deepgram MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 6 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in LlamaIndex only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.

How Vinkius secures
Deepgram for LlamaIndex
Every tool call from LlamaIndex to the Deepgram MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
How do I get a Deepgram API Key?
Log in to the Deepgram Console, navigate to the API Keys section, and create a new key with the necessary permissions.
What is the Nova-3 model?
Nova-3 is Deepgram's latest state-of-the-art transcription model, offering unmatched speed and accuracy for real-world audio.
Can I synthesize speech in different voices?
Yes! The convert_text_to_speech tool allows you to specify models like aura-asteria-en or aura-orion-en for different vocal profiles.
How does LlamaIndex connect to MCP servers?
Use the MCP client adapter to create a connection. LlamaIndex discovers all tools and wraps them as query engine tools compatible with any LlamaIndex agent.
Can I combine MCP tools with vector stores?
Yes. LlamaIndex agents can query Deepgram tools and vector store indexes in the same turn, combining real-time and embedded data for grounded responses.
Does LlamaIndex support async MCP calls?
Yes. LlamaIndex's async agent framework supports concurrent MCP tool calls for high-throughput data processing pipelines.
