Cargo-Cross-Check

About

Rust developers often struggle with validating their projects across diverse platforms like Windows, Linux, macOS, and WASM because `cargo check` analyzes only one target at a time, leading to context switching or multiple workspaces. Cargo-Cross-Check (CCC) solves this by running `cargo check` for multiple configurations in parallel via a dedicated MCP server. It intelligently aggregates diagnostics directly into VS Code's Problems panel, clearly prefixed by target, and offers a unique matrix webview for an intuitive, at-a-glance comparison of issues across all targeted platforms, significantly streamlining cross-platform Rust development workflows.

Key Features

• Docker support for easy remote setup of the MCP server with included Rust toolchain
• Flexible target definition with custom target triples and features via configuration files
• Multi-Configuration Checking for simultaneous target validation across platforms
• 0 GitHub stars
• Matrix View for side-by-side comparison of diagnostics (files × targets)
• Parallel execution on a MCP server with background job queuing for performance

Use Cases

• Define custom target profiles with specific features (e.g., `gui-win`, `gui-gtk`) and check them in parallel.
• Quickly identify which platforms are affected by a specific code change or issue using the color-coded matrix view.
• Simultaneously check a Rust project for compilation errors and warnings across Windows, Linux, and macOS targets.
