Sats4ai MCP Server Overview

cnghockey/sats4ai-mcp-server connects MCP clients to the Sats4AI remote HTTP API for pay-per-use AI and communication services. It covers phone calls, SMS, email, fax, translation, speech, media generation, vision, document processing, and file conversion, with Lightning invoices used to authorize individual operations. Most paid operations follow a discover, invoice, payment-status, and tool-call flow; asynchronous jobs can be monitored and retrieved separately. Reach for it when an agent needs external communication or multimodal processing without service-specific API keys or account setup.

Primary Use Cases for Sats4ai MCP Server:
  • Send an SMS, email, fax, or automated phone call
  • Translate text, audio, or an EPUB into another language
  • Generate and edit images, video, music, speech, or 3D models
  • Extract text and structured data from documents and receipts
