What Speakeasy does

Speakeasy generates MCP servers from an OpenAPI document, producing a TypeScript server whose tools map to the API's operations. It also runs a hosted control plane that builds, proxies and governs MCP servers for an organisation.

Why teams reach for it: It turns an API's existing OpenAPI document into a deployable MCP server, so an API team gets one without hand-writing tools.

What will you use to implement the protocol?

A framework or SDK gives developers pre-built code for creating an MCP server or client, so they don't have to implement the protocol from scratch.
