Speakeasy

Speakeasy is an AI-powered platform that turns your OpenAPI specifications into fully operational API interfaces and tooling, making your API available across multiple environments with minimal manual work. Its primary purpose is to automate the generation and maintenance of ecosystem components such as MCP servers, SDKs, documentation, and Terraform providers from a single source of truth. This helps teams deliver consistent, well-integrated API experiences while reducing engineering overhead and drift between spec and implementation.

The platform can generate type-safe SDKs in multiple languages, tailored to your OpenAPI spec, ensuring client libraries stay in sync as your API evolves. It produces structured, up-to-date API documentation that can be integrated into developer portals or internal knowledge bases. Speakeasy also creates Terraform providers from your OpenAPI definition, enabling infrastructure teams to manage API resources declaratively. By supporting MCP server generation, it allows your APIs to be exposed as tools within model-context-protocol–compatible environments, improving automation and AI integration scenarios.
