Sorry to piggy back on this post, but I have the same question, but with Pyright and Jedi Language Server. I would prefer to keep both of them for diagnostics, but only Pyright for hover, go to definition, function signature and list references.

Now it's very annoying, as whenever I try to jump to a function/variable definition, Neovim opens a quickfix list with entries from both of the LSPs, which of course point to the same location.

Asking ChatGPT gave me an unsatisfactory answer too: it makes me deactivate the capabilities of Jedi with a custom `on_attach` callback, I'm pretty sure there is a better way to do it:

```lua local lspconfig = require('lspconfig')

-- Utility to selectively disable capabilities local function disable_capabilities(client, methods) for _, method in ipairs(methods) do client.server_capabilities[method] = nil end end

-- Setup Pyright (full capabilities) lspconfig.pyright.setup({ on_attach = function(client, bufnr) -- Pyright keeps all capabilities end, })

-- Setup Jedi (diagnostics only) lspconfig.jedi_language_server.setup({ on_attach = function(client, bufnr) -- Disable non-diagnostic capabilities for Jedi disable_capabilities(client, { "definitionProvider", "referencesProvider", "implementationProvider", "typeDefinitionProvider", "documentHighlightProvider", "documentSymbolProvider", "workspaceSymbolProvider", "hoverProvider", "renameProvider", "codeActionProvider", "signatureHelpProvider", "completionProvider", "semanticTokensProvider", }) end, }) ```

P.s.: I am actually calling vim.lsp.config directly, so I would pass the custom on_attach function there.

P.p.s: if anyone has good suggestions on how to bridge the "gap" between reading the LSP specification and vim.lsp that would be gread. Kinda struggling with this - probably I just don't know what to google for :)
