Frequently asked questions
What are voice AI agents?
Voice AI agents are autonomous or assistive AI tools built for voice workflows. This directory tracks 12 of them. On BusinessMCP, any of these agents can be pointed at your company’s unified MCP endpoint so it works from your real data instead of guesswork.
How do I connect a voice agent to my business data?
Connect your tools, ad platforms, and Stripe to BusinessMCP and install the tracking script. We unify everything into one hosted MCP server. You then give any agent a Bearer mcph_* key for your endpoint at /api/mcp, and it can securely read and act on your unified data.
Are these agents tied to a specific AI model?
No. BusinessMCP is model-agnostic. Your unified MCP endpoint works identically whether the agent runs on Claude, GPT, Gemini, or an open model — so you are never locked into one vendor.
One endpoint. Every agent. Your whole business.
Unify your data into a single hosted MCP server and give any voice agent real context to work from.
