Language server for Nim providing symbol navigation, diagnostics, and type resolution for AI agents and editors.

What is the Nim Language Server MCP server?

The Nim Language Server (nimlangserver) is a language server for the Nim programming language that runs as both an LSP server for editors/IDEs and as an MCP server for AI coding agents. It provides symbol navigation, diagnostics, and type resolution capabilities for Nim projects.

nimlangserver enables AI agents like Claude and Cursor to understand and navigate Nim code through symbol lookup, error diagnostics, and type information. It works as both a traditional language server for editors and as an MCP server for AI-assisted development workflows.
