kolivri-voice-mcp — Real AI Phone Line for Claude Code, OpenCode, Cursor & Claude Desktop

kolivri-voice-mcp is a zero-dependency Node.js ESM Model Context Protocol (MCP) server that gives AI coding and operator agents a real phone line powered by Kolivri (app.kolivri.co.il).

Features & Tools

1. kolivri_place_call — Trigger an outbound AI voice call via POST ${KOLIVRI_API_URL}/api/v1/engine/trigger/${webhookId}:
   • Normalizes Israeli (054-1234567) and international E.164 (+972541234567) phone numbers.
   • Enforces language whitelist (he, en, ar, ru, fr, es, de, pt, default he).
   • Enforces KYC verified-caller checks (verifiedCallerId + optional KOLIVRI_VERIFIED_CALLER_ID allowlist).
   • Enforces per-key sliding-window rate limits (KOLIVRI_MAX_CALLS_PER_MINUTE, default 5/min) to prevent robocall loops.
2. kolivri_get_call_status — Fetch call status, structured outcome, transcript, summary, appointment status, and recording URL.
3. kolivri_carrier_forwarding_codes — Generate exact 30-second GSM/IMS call-forwarding dial strings (*61*, *67*, *62*, *004*, *21*, and ##002# reset) for Israeli carriers (partner, pelephone, cellcom, hot_mobile, golan, 019, we4g, bezeq).
4. kolivri_preview_roi — Compute monthly SMB missed-call loss, recovered revenue, and recommend the matching Kolivri unified plan (Starter $69 / ₪247, Business $139 / ₪479, Pro $249 / ₪880).
