AI Connectors: MCP Servers, Claude, and ChatGPT
Your users are asking to access your product inside Claude and ChatGPT. Your competitors are already showing up in AI marketplaces. We build and maintain the connectors that make your product visible in the AI layer.
MCP Servers
Production-ready MCP servers that expose your product to Claude, Cursor, and the growing ecosystem of AI agents. Auth, tool definitions, and marketplace listing included.
Claude & ChatGPT Integrations
Listed in Claude's directory and ChatGPT's App Directory. One MCP server, multiple distribution channels. Ships in your repos, under your accounts.
You Own Everything
No vendor lock-in. No middleware dependency. Code ships on tech you own and endorse. We build it, you own it, we maintain it.

For ~$5K/month, Left Hook took over Quo's in-progress MCP server, finished it, and shipped Claude and ChatGPT connectors — while their engineering team stayed on their product roadmap. The industry quotes $25K–$150K per MCP server build. We deliver all three platforms for a fraction of that.
