⛓

Chainable API

Fluent builder over @modelcontextprotocol/sdk. Add tools, resources, and prompts in one readable chain — no boilerplate setup.

✅

Zod validation

Schema validation is built in. Input errors are caught at the tool layer before they reach your handlers.

🔌

stdio + HTTP

Ship on any transport without changing your handler code. Toggle between local stdio and an Express/HTTP server at startup.

🚀

Deploy CLI

mcpster deploy targets Railway, Fly, or Cloudflare Workers in one command — no per-platform configuration files needed.
