Each figure is the marketplace's own and is never added up across marketplaces. A marketplace that publishes no figure shows none: no number is not zero.

Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
Rust Filesystem
The Rust MCP Filesystem is a high-performance, asynchronous, and lightweight Model Context Protocol (MCP) server built in Rust for secure and efficient filesystem operations. Designed with security in mind, it operates in read-only mode by default and restricts clients from updating allowed directories via MCP Roots unless explicitly enabled, ensuring robust protection against unauthorized access. Leveraging asynchronous I/O, it delivers blazingly fast performance with a minimal resource footprint. Optimized for token efficiency, the Rust MCP Filesystem enables large language models (LLMs) to precisely target searches and edits within specific sections of large files and restrict operations by file size range, making it ideal for efficient file exploration, automation, and system integration.

How to run each
Rust Filesystem As a local MCP server: Docker image
claude mcp add --transport stdio rust-mcp-filesystem -- docker run -i --rm mcp/rust-mcp-filesystemDOS — the trust substrate for agent fleets As a local MCP server: PyPI package
claude mcp add --transport stdio dos-kernel -- uvx --from "dos-kernel[mcp]==0.30.0" dos-kernelCommands built only from what the marketplaces declare; the full set for every client is on each card.
Tools each declares
The marketplaces of DOS — the trust substrate for agent fleets publish no list of tools, so we do not compare tools.
Settings each asks for
Only Rust Filesystem asks for
ALLOW_WRITEENABLE_ROOTS
Only DOS — the trust substrate for agent fleets asks for
DISPATCH_WORKSPACE
Settings as each marketplace publishes them. Asking for fewer is not better in itself.
