77Each plugin connects Claude Code to a language server for one language through the Language Server Protocol (LSP). You install the plugin from Anthropic's official marketplace and the language server binary on your machine.

9<Note>
10 Code intelligence plugins work in terminal sessions. In [cloud sessions](/docs/en/claude-code-on-the-web), Claude Code doesn't start plugin language servers, so Claude gets no diagnostics or code navigation there. To write your own language server plugin, or to connect a language server that has no plugin, see [LSP servers in plugin components](/docs/en/plugins/components#lsp-servers).

1313To get started, find your language in the table under [Install a code intelligence plugin](#install-a-code-intelligence-plugin). The plugins in that table come from Anthropic's [official plugin marketplace](/docs/en/plugins/anthropic-marketplaces).

1919A code intelligence plugin tells Claude Code which command starts the language server and which file extensions it handles. It doesn't include the language server. Install the language server binary first, then the plugin, then confirm the server starts.

43 To find the command that installs the binary, follow the plugin's link in the table to its README. For TypeScript, that command is `npm install -g typescript-language-server typescript`.
41Anthropic maintains every plugin in the table except `liquid-lsp`, which Shopify maintains and the official marketplace lists.

45 After you install the binary, confirm it's on the `PATH` of the shell you start `claude` from, for example with `which typescript-language-server`, or `Get-Command typescript-language-server` in PowerShell.

In a terminal, start Claude Code by running `claude`, then enter this at its prompt, replacing `typescript-lsp` with the plugin the step 1 table lists for your language:

47**2. Install the plugin**

55 A confirmation message says whether the plugin is active now or needs `/reload-plugins`. If the install fails with `Marketplace "claude-plugins-official" not found`, see the [troubleshooting entry for that error](/docs/en/plugins/troubleshooting#marketplace-claude-plugins-official-not-found). To control where the plugin is installed, or to run the install from your shell instead of inside Claude Code, see [Install plugins](/docs/en/plugins/install).

58 <Step title="Confirm the server starts">
59 The language server starts the first time Claude edits a file with one of the plugin's extensions. To see it work, ask Claude to introduce a type error in a file of that language and then fix it. Then check the conversation for a diagnostics line:
51```
52/plugin install typescript-lsp@claude-plugins-official
53```
6054
61 * **A diagnostics line appears**: `Found N new diagnostic issues in M files (ctrl+o to expand)` under the edit that introduced the error means the server started.
62 * **No diagnostics line appears**: run `/plugin` and open the **Errors** tab. A row reading `Executable not found in $PATH: "<binary>"` names the binary to install. If the tab has no such row, see [Troubleshoot code intelligence](#troubleshoot-code-intelligence).

64 After you install a missing binary, Claude Code tries again the next time Claude edits a matching file. If you installed the binary into a directory that isn't on the `PATH` of the shell you started `claude` from, start a new session from a shell where it is.
