MCP Client Capabilities This package strives to be the most up-to-date database of all Model Context Protocol (MCP) clients and their capabilities, to enable MCP servers understand what features an MCP client supports and how to respond to it in order to provide the best user and agent experience. 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 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: typescript { // Client name corresponds to from the MCP client's request, e.g. "ExampleClient" "": { // Display name of the MCP client, e.g. "Example Client" title: string, // URL to the homepage of

Grades come from a rule-based scan built on the SlowMist agent-security taxonomy, covering 11 red-flag categories including credential harvesting, data exfiltration, and curl | sh installers. It is a first-layer scan, not a manual audit — we say so rather than overstate it.
The scale of the problem is documented independently: Liu et al. (2026), in a study of 31,132 agent skills, report that 26.1% contain security vulnerabilities. Our own full-catalog census is published as a citable open dataset.
