What is MCP?


Model Context Protocol (MCP) is an open standard for connecting AI models to external tools and data sources. Think of it as a universal adapter that lets your digital workers interact with any service — from Google Workspace to your own internal APIs.


How Sire Uses MCP


Every tool integration in Sire is an MCP server. When your digital worker needs to send a tweet, query a database, or read a Google Doc, it communicates through MCP's standardized protocol.


Benefits


  • Consistent interface for all tool interactions
  • Security through OAuth 2.1 PKCE authentication
  • Audit trail for every tool invocation
  • Easy to add new integrations without changing the core platform

    • Available Integrations


    Social Media


  • Twitter/X for posting, monitoring, and engagement
  • LinkedIn for professional networking and content
  • Instagram for visual content management

    • Productivity


  • Google Workspace (Docs, Sheets, Gmail, Calendar)
  • Microsoft 365 (Word, Excel, Outlook, Teams)

    • Developer Tools


  • HTTP Client for any REST API
  • SQL Connector for database queries
  • Playwright for browser automation

    • Secure Tunnels


    For on-premise data sources, Sire offers secure tunnel connections:


  • Outbound-only WebSocket connections from your network
  • mTLS authentication for end-to-end encryption
  • No inbound firewall rules required
  • Similar architecture to Cloudflare Tunnel

    • Global Registry


    Browse and install MCP servers from the global registry directly in the Sire marketplace. Community-contributed servers are reviewed and version-pinned for stability.


    Build Your Own


    MCP servers are standalone services that follow a simple protocol. Deploy them on Cloud Run, and they're immediately available to your digital workers.
