I don’t know about other lsps, but gopls has an -mcp flag that makes it run an mcp server. There’s also a jetbrains plugin for claude that gives claude the ability to use a subset of your jetbrains IDE’s features.

I usually have both of those configured when using claude on Go repos, and I still have the same frustrations as the comments above. Gopls has symbol search, but claude almost always uses grep to find uses instead.
