CallSync – Business Call Logging & Management for SIM-Based Teams
Connect your SIM-based business calls, logs, and staff activities with AI. This remote MCP server allows AI agents to search call logs, trigger AI voice transcriptions, analyze caller sentiment, and update CRM contact details securely via OAuth 2.1.
Overview
CallSync MCP Server: Connect SIM-Based Call Logs to AI Agents 📞🤖
CallSync is a powerful mobile-first sales CRM and call tracking ecosystem built for modern sales teams.
This Model Context Protocol (MCP) server allows AI agents (like Claude Desktop, Cursor, and Windsurf) to securely query call data, manage contacts, and trigger voice-to-text analysis directly from your chat sidebar.
💡 Why CallSync?
Traditional VOIP services fail when sales representatives make real phone calls from their mobile SIMs. CallSync solves this:
- SIM-Based Capture: Syncs outgoing and incoming mobile call logs, metadata, and audio recordings automatically from our Android App.
- Instant AI Processing: Automated call transcription, summarization, sentiment classification, and target-intent analysis.
- Unified Sales CRM: A mobile-friendly dashboard to manage leads, tasks, and follow-ups.
⚙️ Available AI Tools & Actions
Once connected, your AI assistant can execute these commands:
list_calls— Browse call logs, check sentiments, read AI summaries, and fetch call recordings.list_callers— Retrieve caller stats (total duration, lead priority, last sync).list_employees— Monitor sales reps' devices, battery life, and sync health.update_identity— Quickly assign names, notes, and priority labels (e.g., "Hot Lead") to phone numbers.trigger_analysis— Manually start AI voice-to-text transcription for any recorded call.archive_identity&delete_caller— Manage data privacy and contact archiving easily.
