kvc-mcp

MCP access is included with every Krystal Voice Caller tier. Use this package to manage a tenant from Claude, Cursor, or any MCP-aware agent.

mcp-name: io.github.KrystalUnity/kvc-mcp

Install

pip install kvc-mcp

Configure

Create or rotate an API token in the Krystal Voice Caller dashboard, then set:

export KVC_API_TOKEN="kvc_token_..."
export KVC_BASE_URL="https://krystalunity.com/api/admin/kvc"

Cursor example:

{
  "mcpServers": {
    "krystal-voice-caller": {
      "command": "kvc-mcp",
      "env": {
        "KVC_API_TOKEN": "kvc_token_..."
      }
    }
  }
}

Tools

The server exposes tenant config, DNC, call history, reception captures, digest send-now, Script Author draft chat, contact upload, outbound captures, and test-call tools. Product availability is enforced by the Krystal Voice Caller API, so Reception-only tenants get inbound/reception tools and Bundle/Premium tenants get outbound Email Hunter tools.

Script approval is not exposed through MCP. Approval stays admin-only in the web UI.

Publish

Operator-only steps:

• cd packages/kvc-mcp && uv build
• uv publish --username __token__ --password "$PYPI_TOKEN"
• Submit an MCP Registry entry named io.github.KrystalUnity/kvc-mcp pointing at the PyPI package.
• Verify from a fresh venv with pip install kvc-mcp && kvc-mcp --help.
