Usage

For End Users

The MCP connectors in this repo power disco.dev - the easiest way to connect your favourite tools to your favourite AI applications using the Model Context Protocol.

Go to disco.dev to get started with zero setup.

For Developers

Use these packages to build your own MCP servers:

npm install @stackone/mcp-connectors @stackone/mcp-config-types

The connectors can be imported and used in your own MCP server implementations, and the config types provide TypeScript definitions for all connector configurations.

Inspiration

"Everything is just fetch wrapped in a function, delivered in pure typescript."

The typing in this package is heavily inspired by the AI SDK by Vercel and the development process has been influenced by the work of Sam at Alchemy.
