Model Context Protocol
The MCP generator is in development. Interested in offering an MCP server for your API? Reach out via Slack or support@buildwithfern.com.
Model Context Protocol (MCP) is an open standard by Anthropic that streamlines how AI applications connect with external data sources and tools, enabling AI agents to directly use your product’s APIs.
A “Built with Fern” MCP server augments your existing TypeScript SDK with MCP capabilities and integrates seamlessly with popular AI-powered tools including Cursor, Claude Desktop, and Windsurf. You can find a full list of MCP clients here.
How it works
Fern can build a production-ready MCP server on top of your existing TypeScript SDK. We maintain the package in its own git
repository, making it easy for your existing developer community to discover and contribute to the project. We can also automatically publish new versions of the package to npm
for you.
End users of a “Built with Fern” MCP server can typically get started with a single config:

Case study: Webflow
We worked with Webflow to launch their official MCP server using the existing Fern-generated TypeScript SDK.
Check out the source code on GitHub and read the announcement from Webflow’s CTO on X:
