MCP.Pizza Chef: nim-lang

nimlangserver is the language server for the Nim programming language. Editors use it for the usual jump-to-definition, autocomplete, and error checking, and it can also run in MCP mode so coding agents such as GitHub Copilot, Claude Code, and Gemini look the same answers up instead of guessing. Installation is a single nimble command, there is no account or key involved, and it needs nimble 0.16.1 or newer plus a nimsuggest from Nim 1.6 or later.
