Speakeasy

Speakeasy helps engineering teams build developer experiences by generating idiomatic SDKs and Terraform providers, and by providing Gram — a managed MCP (Model Context Protocol) offering to create, curate, and host MCP servers for agent tooling. The platform supports OpenAPI-driven SDK generation, TypeScript-native Gram Functions for defining agent tools, and hosted MCP servers with production features like SSO and audit logs. Teams can use Speakeasy for local CLI workflows, automated SDK publishing, and deploying MCP servers to power LLM-based applications.

• SDK generation — Generate handwritten, language-idiomatic SDKs (TypeScript, Python, Go, Java, C# and more) from OpenAPI specs to accelerate integrations.
• MCP hosting (Gram) — Deploy and manage MCP servers (public or private) with built-in playgrounds, log retention, and tool curation to connect LLMs to real APIs.
• Terraform provider generation — Produce Terraform providers from OpenAPI specs to enable reproducible infrastructure-as-code for API resources.
• Gram Functions — Define agent tools in TypeScript to create custom tool behavior and workflows for agents.
• CLI & developer tooling — Use the Speakeasy CLI for generating servers, SDKs, and workflows; integrate with CI/CD and SDK sandboxes.
• Enterprise features — Support for custom domains, OAuth, SSO, audit logs, and concierge onboarding for large teams.

To get started, sign up for the free tier, import an OpenAPI spec or use Gram Functions to define tools, generate SDKs or Terraform providers, and deploy an MCP server for testing and production.
