What does typescript-lsp do?

typescript-lsp is a Claude Code plugin that connects Claude to the TypeScript language server for .ts, .tsx, .js, .jsx, .mts, .cts, .mjs and .cjs files. Through it Claude gets the code intelligence an editor has: going to the definition of a symbol, finding every reference to it and seeing the errors the compiler reports. The plugin only registers the server, which it starts with typescript-language-server --stdio. You install that server yourself first, with npm install -g typescript-language-server typescript or the yarn equivalent. It adds no skills, commands or hooks.

When should you use typescript-lsp?

Use it when

  • Renaming or tracing a function across a TypeScript codebase
  • You want Claude to see type errors as it edits
  • Moving around a large JavaScript project

Skip it when
