Krystal Voice Caller

Overview

Krystal Voice Caller is a Model Context Protocol (MCP) server: Drive a Krystal Voice Caller tenant from Claude, Cursor, or any MCP-aware agent. As an MCP server it plugs straight into AI assistants, exposing its functionality as tools the model can invoke on your behalf.

It runs locally: the Python package kvc-mcp (via uvx) speaks MCP over stdio on your machine. Configuration happens through environment variables — you'll need KVC_API_TOKEN. The current release is v0.1.1, published under the MIT license, with source at KrystalUnity/kvc-mcp on GitHub.

You'll find Krystal Voice Caller in the Communication category here on mcp.site; it connects to Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and any other MCP client — see the install snippets below.
