MCP servers now support Code Mode only

Pierce Clark
Software Engineer
We’ve removed all MCP tool schemes except for “Code Mode," a scheme that exposes just two tools to agents. These include the “docs-search tool” and an “execute-code tool," which allows agents to execute code against your TypeScript SDK on your behalf.
We now will no longer generate or offer other tool schemes such as regular/dynamic tools. Other options such as hosting/publishing your server with Stainless will remain unchanged.
You can find out more about Code Mode and its advantages in our MCP docs.
