Unfortunately, the MCP protocol capability negotiation during the initial handshake is not sufficient for that—see Background bellow for details. In other words, this package is the programmatic version of the community MCP clients table. How it works This package provides a JSON file called mcp-clients.json that lists all known MCP clients, their metadata and capabilities. It's a single JSON file to make it easy for multiple programming languages to access the data while enabling TypeScript type safety for the NPM package. The JSON file contains an object where keys are client names and values an object with information about the MCP client: Note that the client object is inspired by MCP's ClientCapabilites and ServerCapabilites objects, and the respective field types are compatible. Additional fields might be added in the future. IMPORTANT : MCP servers must always prioritize the information received from the MCP client's initalize request via the params.capabilities field (of type ClientCapabilites ) to the capabilities information provided by this package, as it will always be more accurate!
