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.
