Gram by Speakeasy

Gram is Speakeasy's open-source, serverless platform for building and hosting MCP servers from OpenAPI specs or custom TypeScript/Python code, with OAuth 2.1, RBAC, and audit logging.

Gram is built by Speakeasy to make production-grade MCP servers easy to create and operate. Teams can source tools from existing APIs, generating MCP servers from OpenAPI documents, or build tools from scratch using TypeScript functions, and Gram Functions also support Python, opening it to teams without an existing OpenAPI spec. Once a toolset is defined, Gram exposes it as a hosted, serverless MCP server so teams do not manage infrastructure, scaling, or versioning. The speakeasy mcp deploy command pushes a generated server live at getgram.ai, producing a publicly accessible MCP endpoint. Servers can optionally include an OAuth 2.1 proxy with Dynamic Client Registration and PKCE, and are secure by default. For organizations, Gram adds centralized management with role-based access control, audit logging, and compliance reporting across all agent tools, plus a catalog of prebuilt MCP servers for popular third-party APIs. It is an open-source platform, so teams can self-host or use the hosted service, targeting anyone building MCP-based agent tooling at scale.
