An MCP server security audit evaluates credential handling, data exposure, permission scope, and transport security through source-code inspection. It checks for hardcoded secrets, injection risks, path traversal, and excessive permissions to generate a structured risk scorecard with remediation recommendations.

When reviewing a GitHub-hosted MCP server, check for hardcoded secrets, injection risks, path traversal, and vulnerable dependencies. You should also verify least-privilege configurations, missing input validation, and transport security to ensure safe API and database workflows.

You can review local or package-based MCP servers for data exposure by analyzing their source code and transport configurations. The assessment scores data handling practices and permission scopes to determine if file system and network workflows are secure.

Least privilege analysis secures MCP server database workflows by identifying excessive permissions and missing validation in the server's code. Reviewing permission scopes ensures the server only accesses necessary data, reducing potential data exposure risks.

You score an MCP server's security posture by evaluating credential handling, data exposure, permission scope, transport security, code quality, and documentation. This structured risk scorecard helps security teams decide whether the server is safe, conditional, or rejected for internal use.
