extra-small MCP SDK for quick client/server builds.
🚧 This project is under active development, stay tuned!
@modelcontextprotocol/sdk is large and has dependencies on libraries like zod, express, etc. that you probably don't even want to use.
Like xsAI, xsMCP does not force you to use a particular server or schema library and is very small.
Our current target is Streamable HTTP Client / Server (Waiting modelcontextprotocol/typescript-sdk#266 for testing), Stdio have lower priority.
xsMCP v0.1 is targeted to be compatible with the 2025-03-26 revision and is not backward compatible.
