How to Set Up and Use MCP Server Lister
ls-mcp is a CLI tool and MCP server that automatically discovers and lists all MCP server configurations across the AI applications installed on your system, including Claude Desktop, Cursor, VS Code, and other agentic IDEs. It traverses both global and project-scoped configuration files, detects which MCP servers are currently running as processes, and performs security analysis to flag potentially exposed API keys or credentials in environment variables. It supports multiple MCP configuration key formats so it works regardless of which AI tool generated the config.
Prerequisites
- Node.js 18 or higher installed
- At least one AI application with MCP server configurations (Claude Desktop, Cursor, VS Code, etc.)
- An MCP-compatible client if using ls-mcp as a server rather than a CLI tool
- npx available (bundled with Node.js)
Run ls-mcp directly with npx
The fastest way to use ls-mcp is via npx — no installation required. Running the command scans your system for all known MCP configuration locations and prints a summary.
npx ls-mcpScan specific configuration files
You can point ls-mcp at specific JSON config files rather than relying on auto-discovery, which is useful for CI or auditing a particular project.
npx ls-mcp --files ./mcp-config.json ~/.cursor/mcp.jsonInclude providers with no configured servers
By default, providers with zero MCP servers are hidden. Use --all to show every detected provider even if it has no configured servers.
npx ls-mcp --allOutput JSON for programmatic use
Use --json to get machine-readable output including server details, running process status, transport types, and credential warnings.
npx ls-mcp --jsonConfigure as an MCP server in Claude Desktop
To use ls-mcp as an MCP tool (so Claude can query your MCP configuration), add it to your claude_desktop_config.json.

Client configuration
Add ls-mcp as an MCP server so Claude or another AI assistant can introspect your MCP setup on demand.
{
"mcpServers": {
"ls-mcp": {
"command": "npx",
"args": ["-y", "ls-mcp"]
}
}
}Prompts to try
Use ls-mcp through Claude to audit and explore your MCP server setup.
- "List all MCP servers configured on my system"
- "Which MCP servers are currently running?"
- "Are there any API keys exposed in my MCP server configurations?"
- "Show me the MCP servers configured for Cursor"
- "Audit my MCP configurations and flag any credential warnings"Troubleshooting MCP Server Lister
No MCP servers are detected even though they are configured
Run with `NODE_DEBUG=ls-mcp npx ls-mcp` to enable verbose logging and see which paths are being scanned. Also try `npx ls-mcp --all` to include providers with empty configs. The tool looks for standard config file locations; if yours is non-standard, use `--files` to specify it directly.
Credential warnings appear for API keys in environment variables
ls-mcp flags environment variable values that look like secrets for security awareness. Review the flagged servers and consider using a secrets manager or referencing variables by name rather than embedding plaintext values in config files.
JSON output is missing some providers
By default only providers with at least one server are included. Add `--all` to the command to include all detected providers regardless of whether they have servers configured.
