A [Claude Code](https://claude.com/claude-code) marketplace that provides a TypeScript
language server backed by the **native TypeScript 7** server (`typescript@rc`

), launched as
`tsc --lsp --stdio`

.

It replaces the official `typescript-lsp`

plugin (which uses the Node-based
`typescript-language-server`

wrapper around the classic `tsserver`

) with the faster native
Go implementation.

Unofficial.This is a community project and isnotaffiliated with, endorsed by, or maintained by Microsoft or the TypeScript team. "TypeScript" and`tsc`

are products of Microsoft; this repo just wires the`typescript@rc`

LSP into Claude Code. Provided as-is.

```
.claude-plugin/marketplace.json   # marketplace "ts7-lsp-marketplace" → plugin "ts7-lsp"
plugins/ts7-lsp/README.md         # install + enable instructions
npm install -g typescript@rc                       # a TS7 `tsc` on PATH — any package manager works
/plugin marketplace add mjn298/ts7-lsp-plugin      # add this marketplace straight from GitHub
/plugin install ts7-lsp@ts7-lsp-marketplace
/plugin disable typescript-lsp@claude-plugins-official   # ONLY if you'd already installed the official TS LSP
/reload-plugins
```
