What is BridgeKit?

BridgeKit is a multi-tenant MCP (Model Context Protocol) SaaS platform that connects Claude Desktop to your productivity tools. Instead of switching between apps, you talk to Claude:

"Check my unreplied emails from this week and draft responses"

"Send a message to #core-team on Slack saying the feature is live"

"Create a Google Doc summarizing our Q4 results and share it with the team"

"Search my Drive for the proposal we sent last month"

106 tools across 10 platforms - all accessible through natural conversation.

Platform Compatibility

BridgeKit is a remote MCP server - add it once on claude.ai and it syncs to Desktop, Web, and Mobile automatically.
