MCPVault is an independent, quality-first directory for the Model Context Protocol (MCP) ecosystem, built to help developers discover, evaluate, and monitor MCP servers. It indexes more than 19,000 servers and provides searchable listings with information such as maintenance activity, documentation, licenses, client compatibility, and required authentication. Quality grades are recalculated nightly, while verified listings earn their badge through a real MCP handshake that is repeated weekly.

Developers can browse the directory and run live tests in isolated environments before installing a package. Server owners can claim an existing listing or submit a repository, then manage descriptions, compatibility details, installation instructions, and logos. Optional verification adds a badge and other listing benefits. MCPVault also offers weekly static security scans for claimed servers, displaying code-access findings without executing the code, and a paid monitoring service that checks up to five servers daily, provides public status pages, and sends email alerts about failures or tool changes.
