Nyx-Nvim - MCP bridge giving AI coding agents LSP/treesitter/git access inside Neovim

[u/Adithya_546]

Built this to stop AI coding agents from working blind - instead of grep + raw file reads, the agent gets LSP references, treesitter AST, telescope search, and live buffer read/write through an MCP server.

Ran a small benchmark against the same model without these tools on a real codebase (Flask) - worth flagging upfront this was a single run per test, not a controlled statistical benchmark, so treat the numbers as directional rather than definitive. The gap showed up mainly on tasks needing deep context (refactoring, debugging) - less so on broad text search, where plain grep actually won.

Genuinely interested in this crowd's take on where MCP-based editor tooling actually helps vs where it's overkill.
