How to Set Up and Use MCP Security.io
MCP Security.io (modelcontextprotocol-security.io) is the official documentation and community hub for the Model Context Protocol Security initiative, a Cloud Security Alliance (CSA) community project. It provides security teams, developers, and operations engineers with comprehensive MCP hardening guides, a TTP (Tactics, Techniques, and Procedures) threat matrix, a known vulnerability database with CVE tracking, secure architecture reference patterns, and a suite of open-source audit and assessment tools. The site exists to address the production security challenges that arise when AI agents use MCP to interact with external systems, APIs, and sensitive data sources.
Prerequisites
- A modern web browser to access the documentation at modelcontextprotocol-security.io
- Ruby and Bundler (only required for running the Jekyll site locally for contribution)
- Git for cloning the repository and contributing security content
- An MCP deployment to audit (to use the associated mcpserver-audit, mcpserver-finder, or mcpserver-operator tools)
Review the MCP security threat landscape
Start at the TTP Matrix View to understand the full range of security tactics, techniques, and procedures that apply to MCP deployments. Browse the Known Vulnerabilities database for CVEs affecting MCP servers you use.
Assess your current MCP deployment
Use the mcpserver-audit tool (MCP Security Expert) from the ecosystem to run a risk assessment against your deployed MCP servers. Clone and configure the audit tool from its repository.
git clone https://github.com/ModelContextProtocol-Security/mcpserver-audit
cd mcpserver-audit
# Follow the README to configure and run the auditApply the Hardening Guide
Work through the 10-part hardening framework at modelcontextprotocol-security.io/hardening/ to systematically address privilege escalation, data exposure, and supply chain risks in your MCP setup.
Discover and evaluate MCP servers
Use the mcpserver-finder tool to discover available MCP servers and evaluate their security posture before adding them to your environment.
git clone https://github.com/ModelContextProtocol-Security/mcpserver-finder
cd mcpserver-finder
# Follow the README to search and evaluate MCP serversRun the documentation site locally (for contributors)
Clone the website repository and use the provided setup and serve scripts to run the Jekyll site locally. The site source lives in the docs/ subdirectory.
git clone https://github.com/ModelContextProtocol-Security/modelcontextprotocol-security.io
cd modelcontextprotocol-security.io/docs
./setup.sh
./serve.sh
# Visit http://localhost:4000Contribute to the vulnerability database
Submit vulnerability findings, CVE entries, or audit results to the community databases to help the ecosystem maintain an up-to-date view of MCP security risks.
# Vulnerability submissions
git clone https://github.com/ModelContextProtocol-Security/vulnerability-db
# Audit results
git clone https://github.com/ModelContextProtocol-Security/audit-dbMCP Security.io Examples
Client configuration
This project is a documentation hub and tool ecosystem, not a runtime MCP server package. The mcpserver-audit tool can be integrated as an MCP server for AI-assisted security assessments.

Jekyll site fails to build locally with gem dependency errors
Run ./setup.sh from within the docs/ directory, not the repo root. This script installs the correct Ruby gem versions. Ensure Ruby 3.x and Bundler are installed: `gem install bundler`.
Cannot find a specific CVE or TTP in the database
Use GitHub Discussions at github.com/orgs/ModelContextProtocol-Security/discussions to ask the community, or open an issue on the relevant repository (vulnerability-db or audit-db) to request that an entry be added.
mcpserver-audit tool reports connection errors to the MCP server under test
Verify the MCP server is running and its endpoint is reachable from the audit tool's environment. Check that any required API keys or authentication tokens for the target MCP server are configured correctly in the audit tool's settings.
