mcpls-0.3.5 is not a library.

mcpls

Give your AI agent a compiler's eye.

The mcpls CLI exposes language server intelligence through MCP. One binary, any language, zero runtime dependencies.

[!TIP] Graceful degradation means you don't need every language server installed. If one fails, mcpls continues with available servers.

cargo install mcpls
