slack-mcp-client

The project demonstrates robust security practices, including the use of environment variables for secrets, explicit access control for Slack interactions, tool-level permissions (allow/block lists) for MCP servers, and integration of security scanning (Trivy, govulncheck) in its CI/CD pipeline. The use of `exec.Command` for stdio MCP servers is configured by administrators, not directly exposed to untrusted user input. Network policies are also supported in Helm deployments. The primary security risk lies in misconfiguration (e.g., allowing overly permissive tools or access) rather than inherent vulnerabilities in the client's codebase itself, which provides the necessary controls for secure operation.
