LSP MCP Bridge

Universal MCP bridge to LSP servers. One binary, 6 languages, config-driven.

Quick Install

Automated & IDE Setup

Copy the AI prompt to install this server into Claude Code, Cursor, or another agent — or use 1-click editor setup below.

One-click editor setup isn’t available for this listing yet — we don’t have a confirmed install command, and we’d rather show nothing than point your editor at the wrong package or host. Follow the project’s own setup instructions, linked above.

Manual Client & Custom JSON ConfigExpand JSON ▾

No confirmed setup config for this listing yet. We only publish a config block when the install details come from the project itself — its README, its docs, or a verified owner. We haven’t found those for LSP-MCP Bridge, and we’d rather show nothing than a guess you’d paste into your client. Follow the project’s own setup instructions for the current steps.
