Hey Product Hunt!
We just went live with the SigmaMind MCP Server, and we re on a mission to end "infrastructure hell" for voice developers.
For the last year at SigmaMind (YC S22), we ve watched builders struggle to stitch together telephony, low-latency models, and fragmented APIs.
Today, we re changing that. We ve built a way to configure and deploy production-grade voice agents directly from your IDE (Cursor, Claude Code, etc.) using the Model Context Protocol. No more manual glue - just one prompt to connect your model, pick a voice, and get a live phone number.
We d love your feedback on the launch today:
SigmaMind AI
Hey 👋
We’re Ashish and Pratik, founders of SigmaMind AI.
After watching developers jump between dashboards, docs tabs, and their IDE just to configure a single voice agent - we knew the problem wasn't the technology. It was the workflow.
So we built SigmaMind MCP server.
Open Cursor, Claude Code, or VS Code. Type what you want:
"Build a customer support voice agent. GPT-4o. ElevenLabs, calm British female. Agent speaks first. Extract sentiment and escalation flags after every call."
That exact spec deploys. No dashboard opened. No context switching.
Here's what you're actually controlling from that one prompt:
→ LLM Model - GPT-4o, Claude, Gemini, or your own
→ Voice & TTS - pick the exact voice experience
→ Conversation Flow - who speaks first, how it behaves
→ Welcome Message - define the opening line
→ Background Audio - optional, on-brand
→ Post-Call Insights - sentiment, intent, escalation
Every layer configurable. All from natural language.
And telephony is built in - buy numbers or bring your own, assign to agents instantly, run real calls not simulations.
Under the hood:
→ Sub-800ms latency
→ IVR and phone trees navigation
→ Built-in VAD (Voice activity detection)
→ Noise cancellation for noisy background environments
→ Model-agnostic (Deepgram, GPT, ElevenLabs, or your own stack)
→ Multimodal (voice, chat, email - one agent brain)
→ Parallel tool calling for real-world actions
