What it does
A TypeScript framework for building MCP servers. It handles tool discovery, several transports and input validation, and filters the data that reaches the model through typed rules. It also includes a SKILL.md so coding agents can follow its conventions when generating a server.
Use cases
- 01Build an internal MCP server for company data
- 02Validate tool inputs before they reach your systems
- 03Restrict which fields an agent can see
