MCAP is a modular, performant, and serialization-agnostic container file format designed for pub/sub messaging and robotics applications. It provides a flexible and efficient way to store and stream structured data, making it ideal for use in resource-constrained environments or high-throughput systems. The project offers multi-language support, including C++, Go, Python, JavaScript/TypeScript, Swift, and Rust, along with tools like the MCAP CLI for file inspection and manipulation.
