7. Model Context Protocol (MCP) AI Integration

Section titled “7. Model Context Protocol (MCP) AI Integration”

The Ring2All Platform Copilot integrates with the Fax Viewer archive via the Model Context Protocol (MCP) to audit incoming/outgoing fax transmissions, diagnose delivery errors, inspect transfer bitrates, and verify page delivery.

Tool Name Operation Primary Parameters Description
query_fax_history History Search direction (“all”, “inbound”, “outbound”), search (string, optional), limit (number) Retrieves recent fax transmission logs, showing timestamp, remote phone number, caller ID, page count, and success status.
get_fax_details Detailed Diagnostic Inspection faxLogId (number) Fetches complete transmission diagnostics for a specific fax record, including result codes, transfer rate, and rendered PDF path.
list_fax_devices Device Inventory search (string, optional) Queries configured fax devices to correlate activity with specific endpoints.
  • Domain Scope Isolation: Users and Copilot sessions can only query fax logs belonging to their authenticated tenant domain (WHERE domain_id = :domain_id).
  • Read-Only Inspection: Querying fax history and viewing transmission details does not delete or truncate files on disk.
  • Path Sanitization: Direct disk paths are never exposed to untrusted external callers; file retrieval relies on secure authenticated download tokens.
