What is Catenary?

Catenary bridges MCP (Model Context Protocol) and LSP (Language Server Protocol), giving AI assistants like Claude access to real IDE features: hover docs, go-to-definition, find references, diagnostics, completions, rename, and more.

Getting Started

1. Install the binary

cargo install catenary-mcp

2. Configure language servers — see Configuration

3. Connect your AI assistant

Plugins and extensions register the MCP server and hooks for post-edit diagnostics, file locking, and root sync. The binary must be on your PATH.

Claude Code:

/plugin marketplace add MarkWells-Dev/Catenary
/plugin install catenary@catenary

Gemini CLI:

gemini extensions install https://github.com/MarkWells-Dev/Catenary

See Installation for Claude Desktop, manual setup, and other MCP clients.

4. Set up language servers — see LSP Servers for per-language guides.
