How to Set Up and Use MCP Client Capabilities
MCP Client Capabilities is a reference MCP server and data package that indexes 44+ Model Context Protocol clients — including Claude.ai, Claude Code, Cursor, VS Code, GitHub Copilot, ChatGPT, Gemini CLI, and Cline — along with their exact capability support matrix. It exposes structured data about which clients support resources, prompts, tools, discovery, sampling, tasks, roots, and elicitation, letting developers and AI assistants instantly look up compatibility without digging through documentation. It is maintained by Apify and available as both an npm package and a Python package.
Prerequisites
- Node.js 16+ for npx-based usage, or Python 3.8+ for the Python package
- An MCP-compatible client such as Claude Desktop or Claude Code to consume the server
- npm or pip for installation
Run the MCP server with npx
The fastest way to start the server without installing it globally is with npx. Use the -y flag to skip the confirmation prompt.
npx -y mcp-client-capabilitiesOr install the npm package
Install globally for repeated use without npx overhead.
npm install -g mcp-client-capabilities
mcp-client-capabilitiesRegister with your MCP client
Add the server to claude_desktop_config.json (Claude Desktop) or your chosen client's MCP configuration file.
# Edit ~/Library/Application Support/Claude/claude_desktop_config.jsonRestart your client and verify
Restart Claude Desktop or your MCP client and confirm the server is active by querying client data.
# In your Claude session:
"List all MCP clients in the capabilities index"Use as a library in your own code
The package also exports the client data directly for use in TypeScript or Python projects that need to check capabilities programmatically.
# TypeScript
import { mcpClients } from 'mcp-client-capabilities';
const client = mcpClients['claude-ai'];
console.log(client.title, client.capabilities);
# Python
from mcp_client_capabilities import mcp_clients
client = mcp_clients['claude-ai']MCP Client Capabilities Examples
Client configuration
Add the MCP Client Capabilities server to Claude Desktop:
{
"mcpServers": {
"mcp-client-capabilities": {
"command": "npx",
"args": ["-y", "mcp-client-capabilities"]
}
}
}Prompts to try
Use these prompts to query the MCP client capabilities index through your AI assistant:
- "Which MCP clients support the sampling capability?"
- "Does Cursor support MCP resource access?"
- "Compare Claude Code and VS Code in terms of MCP capability support"
- "List all MCP clients that support elicitation"
- "What MCP capabilities does GitHub Copilot support?"Troubleshooting MCP Client Capabilities
npx -y mcp-client-capabilities fails with network errors
Ensure you have a stable internet connection and npm is configured to use the correct registry. Try: npm install -g mcp-client-capabilities as an alternative, then run mcp-client-capabilities directly.
Client data appears outdated for a newly released MCP client
The data is maintained in the Apify GitHub repository. Check https://github.com/apify/mcp-client-capabilities for the latest version and update your package: npm install -g mcp-client-capabilities@latest.
TypeScript import fails with 'module not found'
Ensure you installed the package as a dependency: npm install mcp-client-capabilities. If using ES modules, check that your tsconfig.json has moduleResolution set to 'node16' or 'bundler'.
