Yeah, I posted here because I was completely blindsided when my claude asked if I wanted to install a go lsp. I didnt even know that was a thing. A little googling led to this changelog from 3 days ago, but I was surprised I hadnt seen any previous mentions of this online (from either creators, anthropic, or HN posts).

I am disabling it for now since my flow is fine at the moment, I'll let others validate the usefulness first.

I got an unexpected offer to install the LSP plugin for swift-lsp at 6:30pm pst on 12/19pm and again yesterday afternoon the text reads:

LSP Plugin Recommendation

LSP provides code intelligence like go-to-definition and error checking

Plugin: swift-lsp

Swift language server (SourceKit-LSP) for code intelligence Triggered by: •swift files

Would you like to install this LSP plugin? › 1. Yes, install swift-lsp 2. No, not now 3. Never for swift-lsp 4. Disable all LSP recommendations

I had a conversation with Claude code 2 weeks ago where it mentioned early support for LSP had been added into Claude code. Have been working on a LSP for a custom language since then.

I am on the latest version of Claude Code and nothing comes up when I follow this and search for "mcp". Looks like this feature is quite undercooked at the moment. I'm hoping for a more straightforward way to enable this and ensure the LSP is being used by Claude in the future.

Perhaps because you are searching for "mcp" and not "lsp"?

LOL yeah that would be a solid guess but I just sanity checked and I messed it up only in the comment, in Claude Code when I search for "lsp" I still get no matches.

Upgrade claude code, on old versions the anthropic marketplace is not enabled by default

Interesting. I'd guess you don't have the Claude Plugins marketplace enabled, but I very much agree that the whole plugins/marketplace system seems half-baked in Claude Code.

might need to upgrade claude code

huh, well i got it on my work account, but my personal claude pro account still doesn't seem to have it available (2.0.76)

If you want to add custom lsps, they need to be wrapped in a Claude code plugin which is where the little bit of actual documentation can be found https://code.claude.com/docs/en/plugins-reference

Thanks! I saw typescript-lsp in the plugins list, but I wasn't sure if that was related.

That works, but even after installing the plugin, it doesn't seem to run the language server itself, so it doesn't seem to do anything in the terminal version of claude-code.

I'd be disappointed if this were a feature only for the vscode version.

Have you figured out what triggers it?

No, and it looks like this functionality was released/announced prematurely:

https://github.com/anthropics/claude-code/issues/14803#issue...

https://github.com/anthropics/claude-code/issues/13952#issue...

https://github.com/anthropics/claude-code/issues/13952#issue...

My permissions prompt isnt quite working right with it either. It pops up but isnt blocking, so claude continues editing and asking for other permissions which replaces this prompt. Then when you confirm those prompts, it shows the LSP prompt again. Definitely needs polish (and explanations on how it even benefits the agent)

Go to /plugins, then marketplaces, then select official and update marketplace. This did it for me.

this!
