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.

Installation

cargo install mcpls

Usage

mcpls                           # Run with defaults
mcpls --log-level debug         # Verbose output
mcpls --config ./mcpls.toml     # Custom config
