mcp -security-standard

The MCP Server Security Standard (MSSS) implements a structured, risk-based approach to enabling AI tools and prompts while enforcing strong security controls. MSSS exposes a configurable MCP server that coordinates tool usage, input validation, access control, and auditing across deployment profiles. The server is designed to be deployed using containerization (Docker in this guide) to ensure reproducible environments and integrated with reporting schemas for machine-readable verification. Tools, profiles, and controls are aligned with the MSSS 24 security controls across 8 domains, supporting automated verification and threat modeling as your AI deployment scales.

Once running, you can interact with the MCP server to validate tool invocations, enforce arguments and input constraints, perform authorization checks, and generate audit logs. The included reporting schemas enable you to produce JSON-based evidence of compliance with the selected level (L1–L4) and deployment profile. Use the deployment profiles to tailor the security posture to your environment, then assess and map controls to your real-world usage to maintain continuous assurance.

Prerequisites:

• Docker installed and running on your host
• Git installed
• Access to a terminal/CLI

Install and run MSSS using Docker:

1. Pull the latest MSSS image (or build locally if you have a Dockerfile): docker pull mcp-server-security-standard:latest

2. Run the MCP server container: docker run -d --name mcp-server-security-standard -p 8080:80 mcp-server-security-standard:latest

3. Verify the server is up: docker ps curl http://localhost:8080/health

Optional: clone and run from source (if you prefer developing against the repository):

1. git clone https://github.com/mcp-security-standard/mcp-server-security-standard.git
2. cd mcp-server-security-standard
3. Follow any repository-specific install steps in the README (e.g., install dependencies) and run the server as described there.

Notes:

• Adjust port mappings as needed to fit your environment and firewall rules.
• If you use TLS/HTTPS in front of the MCP server, ensure certificates are mounted and the reverse proxy is configured accordingly.

Tips and reminders:

• Review the deployment profiles in v0.1/standard/profiles.md to choose the appropriate security posture for your environment.
• Ensure you enable the appropriate Level (L1–L4) based on your data sensitivity and risk tolerance; higher levels provide stronger protections but may add overhead.
• Enable comprehensive audit logging (MSSS LOG controls) to support incident response and compliance reporting.
• Regularly verify that input validation (MCP-INPUT-01, MCP-INPUT-02) and command execution controls (MCP-EXEC-01, MCP-EXEC-02) are enforced in your runtime environment.
• If using Docker, keep image provenance in mind and pin to a specific version tag to prevent unexpected updates; periodically audit the image for vulnerabilities.
• For testing, use the JSON reporting schemas to generate machine-readable attestations of compliance for internal audits or external assessments.
