mcp-gitlab

The server demonstrates strong security practices: - Robust input validation (e.g., `validate_project_path`, `validate_file_path`) prevents common injection attacks and path traversal. - Output sanitization (`sanitize_output`) explicitly redacts GitLab tokens (e.g., `glpat-`) from responses. - Log messages are sanitized (`sanitize_log_message`) to prevent log injection. - The `download_job_artifact` tool explicitly returns artifact metadata rather than the file content itself, preventing unauthorized data exfiltration through the LLM. - Authentication tokens (`GITLAB_PRIVATE_TOKEN`, `GITLAB_OAUTH_TOKEN`) are correctly loaded from environment variables, avoiding hardcoding. - The `GitDetector` accesses local `.git` files, which, while standard for Git, could be a low-risk vector if arbitrary paths were accepted without proper context from an LLM. However, path inputs are sanitized, mitigating this risk significantly.
