What is the AssemblyAI MCP Server?
Connect your AssemblyAI account to any AI agent and take full control of your high-fidelity audio transcription and speech intelligence workflows through natural conversation.
What you can do
- Speech-to-Text Orchestration — Programmatically transcribe public audio or video URLs using state-of-the-art MARS models with superhuman accuracy
- Audio Intelligence — Extract high-fidelity insights including automated summaries, sentiment analysis, and topic detection directly through your agent
- Speaker Diarization Architecture — Retrieve detailed utterances separated by speaker labels to coordinate meeting minutes and interview transcripts perfectly
- Content Discovery — Access automated chapters and high-fidelity video recaps to maintain a perfectly coordinated media library
- Lifecycle Management — Monitor transcription job status and manage your directory of recent transcripts directly through your agent for instant reporting
How it works
1. Subscribe to this server
2. Retrieve your API Key from the AssemblyAI dashboard

How Vinkius secures
AssemblyAI for Pydantic AI
Every tool call from Pydantic AI to the AssemblyAI 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 find my AssemblyAI API Key?
Log in to your account, navigate to the API Keys section in your dashboard, and copy your personal token.
Can I automatically summarize audio via AI?
Yes! Enable the summarization option when transcribing, then use the get_summary tool to retrieve the high-fidelity AI synopsis.
How do I check transcription status?
Use the get_transcript tool with the job ID provided at submission to monitor the status (Queued, Processing, Completed) in real-time.
How does Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your AssemblyAI MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
