mason-lspconfig install pylsp-mypy

[Pakrohk]

I am replacing nvpak requirements with mason In the past, I used null-ls to solve these needs, installing plugins for lsp like pylsp-mypy, but it seems that mason-lspconfig can only install lsp servers automatically, is there a solution for this issue?

-- Auto server setup
local auto_server_setup = function(server_name)
    nvim_lsp[server_name].setup({
        on_attach = on_attach,
        capabilities = capabilities,
    })
end

-- Auto install LSP List
mason_lspconfig.setup({
    auto_install = true,
    ensure_installed = {
        "lua_ls",
        "pylsp",
        "html",
        "cssls",
    },
})

-- Setup LSP configurations after installation
mason_lspconfig.setup_handlers({
    ["lua_ls"] = function()
        nvim_lsp.lua_ls.setup({
            settings = {
                Lua = {
                    completion = {
                        callSnippet = "Replace",
                    },
                    diagnostics = {
                        enable = true,
                        globals = { "vim" },
                        underline = true,     -- underline errors/warnings in the code
                        severity_sort = true, -- sort errors/warnings by severity
                        signs = true,         -- add signs in the gutter for errors/warnings
                    },
                    workspace = { checkThirdParty = false },
                },
            },
            on_attach = on_attach,
            capabilities = capabilities,
        })
    end,

    ["pylsp"] = function()
        nvim_lsp.pylsp.setup({
            cmd = { "pylsp" },
            filetypes = { "python" },
            root_dir = nvim_lsp.util.root_pattern(".git", "venv", ".env", "main.py"),
            settings = {
                pylsp = {
                    plugins = {
                        pylsp_mypy = { enabled = true },
                        pylsp_black = { enabled = true },
                        pylsp_isort = { enabled = true },
                        -- disabled standard plugins
                        autopep8 = { enabled = false }, -- covered by black
                        yapf = { enabled = false },     -- covered by black
                        pycodestyle = { enabled = false },
                        pydocstyle = { enabled = false },
                    },
                },
            },
            single_file_support = true,
            on_attach = on_attach,
            capabilities = capabilities,
        })
    end,
    ["html"] = function()
        nvim_lsp.html.setup({
            on_attach = on_attach,
            capabilities = capabilities,
        })
    end,
    ["cssls"] = function()
        nvim_lsp.cssls.setup({
            on_attach = on_attach,
            capabilities = capabilities,
        })
    end,
})

-- auto config other servers
if auto_config_servers then
    for _, server_name in ipairs(auto_config_servers) do
        auto_server_setup(server_name)
    end
end

Of course, I'm not very good at writing in English, I hope I have conveyed my meaning well.

Well, I searched for similar topics and came across the following thread
#908
I think it has answered my question to some extent, but there are still some questions left.
Does this method cover the prerequisites of all packages? For example spell-check or bash-format
Another question, what if an lsp was not set by default? Is there a way to make more effective suggestions in it? For example, let's assume that pylsp was not installed, was it not installed after installing mypy?

I'm looking for that every time I enter a file with a new format, I don't have to enter the LspInstall command. Has mason prepared a function for me to solve this problem?
