Speakeasy reads a Swagger/OpenAPI spec file and generates typed SDKs in multiple languages from it automatically.
→ Production-quality SDKs auto-generated from the API spec — when the spec changes, the SDK regenerates without manual work.
Speakeasy reads OpenAPI specs linted and validated by Redocly, generating SDKs from a spec that's already been quality-checked.
→ SDK generation from a validated spec — Redocly catches spec errors before Speakeasy generates code from them.
Speakeasy generates SDKs from OpenAPI specs designed and validated in Stoplight Studio.
→ SDK generation from a visually designed, validated spec — Stoplight handles spec authoring, Speakeasy handles code generation.
Speakeasy can generate MCP server wrappers from OpenAPI specs, turning any REST API into a callable MCP tool.
→ Any API with an OpenAPI spec becomes an MCP server — Speakeasy bridges the spec world and the MCP tool ecosystem.
Speakeasy generates Python MCP server wrappers from OpenAPI specs using the Python MCP SDK under the hood.
→ Python-based MCP servers generated from existing API specs — instant MCP access to any Python-friendly REST API.
