One Connector

Turn Hours of Manual Work
Into Seconds of Automation

BigMCP lets you compose custom workflows that orchestrate multiple services with a single command. Create your own multi-tool compositions once, then execute them instantly from anywhere.

  • Compose workflows from your existing tools (HubSpot, Drive, Gmail, Slack...)
  • Execute multi-service operations with natural language
  • Your custom compositions become callable tools for your whole team
  • Run complex workflows from Claude—desktop or mobile
The Challenge

The MCP Governance Challenge

As your MCP ecosystem grows, managing tools becomes complex and risky

Without BigMCP

  • ×Each MCP server manages its own credentials
  • ×No centralized access control or auditing
  • ×Manual tool orchestration across servers
  • ×Desktop-only, no mobile access
  • ×Zero visibility into usage patterns
  • ×Impossible to enforce governance policies

With BigMCP

  • Unified OAuth authentication
  • Organization-level RBAC with 4 role tiers
  • Automated tool composition & workflows
  • Access from desktop, mobile, anywhere
  • Comprehensive usage tracking & metrics
  • Single governance layer for all MCPs
