How to Set Up and Use MCP Security Checklist
The MCP Security Checklist server by Helixar AI provides AI assistants with a structured, queryable security checklist for teams building and deploying Model Context Protocol servers, covering authentication, input validation, tool exposure, data handling, network security, logging, and CISO-level summaries across seven categories. Rather than exposing live integrations, it serves as an authoritative reference tool that lets Claude answer detailed security questions about MCP deployment best practices — from scoping tool permissions to protecting against prompt injection attacks. Security engineers, platform teams, and technical leaders use it to get actionable, category-specific guidance inline with their MCP architecture reviews.
Prerequisites
- Node.js 16 or later
- An MCP-compatible client such as Claude Desktop or Claude Code
- Basic familiarity with MCP server deployment and security concepts
Run the server via npx
The server can be run directly via npx without a global install, making it easy to add to any MCP client configuration.
npx mcp-security-checklistAdd the server to Claude Desktop config
Open your claude_desktop_config.json and add the mcp-security-checklist server entry using npx so it always runs the latest version.
{
"mcpServers": {
"mcp-security-checklist": {
"command": "npx",
"args": ["mcp-security-checklist"]
}
}
}Restart Claude Desktop
Quit and reopen Claude Desktop to pick up the new MCP server. The security checklist tools should now be available.
Query a security category
Ask Claude to retrieve the authentication checklist or input validation controls to confirm the server is responding with checklist content from the seven security domains.

}Prompts to try
Example prompts that use the security checklist to guide MCP server hardening and review.
- "What are the authentication controls I need to implement before deploying my MCP server to production?"
- "Show me the input validation checklist for MCP tool parameters"
- "What does the checklist say about logging tool invocations and protecting against prompt injection?"
- "Give me a CISO-level summary of the top 10 MCP security controls I should brief my leadership on"
- "Review my MCP server design: I'm using long-lived API keys and shared credentials — what checklist items am I failing?"Troubleshooting MCP Security Checklist
npx mcp-security-checklist fails with package not found
Ensure you have Node.js 16 or later installed and npm is accessible. Try running 'npm cache clean --force' and retry, or install the package globally first with 'npm install -g mcp-security-checklist'.
The server starts but Claude does not return checklist content
The checklist content is sourced from the bundled checklist.json covering seven categories (auth, input-validation, tool-exposure, data-handling, network, logging, ciso-summary). Confirm the server is running by checking Claude Desktop logs for MCP connection success.
Want to access the raw checklist data outside of Claude
The checklist is also available as machine-readable checklist.json and checklist.yaml at https://github.com/Helixar-AI/mcp-security-checklist, which you can download and integrate into your own tooling or CI pipelines.
