About Speakeasy
Speakeasy generates production MCP servers and SDKs from an OpenAPI spec, offers the open-source Gram platform, and provides an MCP Gateway with SSO, policy, observability, and audit.
Speakeasy started as an SDK generation platform and has become a major player in connecting APIs to AI agents through the Model Context Protocol. From an OpenAPI specification it generates fully customizable, production-ready MCP server code that teams own and deploy on their own infrastructure, supporting both MCP transports (Streamable HTTP and STDIO) along with SSE, streaming, and automatic Base64 encoding for binary responses. It also supports code-mode execution, where tool calls run in a sandbox to dramatically reduce token consumption. Around this, Speakeasy has built Gram, the open-source platform for building MCP servers that perform, and in 2026 launched the Speakeasy MCP Gateway, a single entry point between every AI agent and every MCP server with SSO, policy enforcement, observability, and audit. Together these products form an AI control plane for securely connecting, securing, observing, and distributing agents, MCP servers, and skills across an organization. Speakeasy is a strong fit for API-first companies that want to make their APIs agent-ready with reliability and governance.
TL;DR
Speakeasy generates production MCP servers and SDKs from OpenAPI, offers the open-source Gram platform, and adds an MCP Gateway with SSO, policy, observability, and audit.
