check_codeAnalyze inline code for security vulnerabilities (OWASP Top 10, XSS, SQL injection, insecure patterns). Pass code as a string parameter. For scanning files on disk, use scan_file instead. Example: check_code({code: 'app.get(...)', language: 'javascript'})check_projectScan multiple files for security vulnerabilities and generate a project-wide security report with a security score. Use this for comprehensive security audits.get_security_docsGet security best practices and remediation guidance for a specific topic, framework, or vulnerability type. Covers OWASP Top 10, framework-specific hardening (Next.js, Supabase, Stripe), and secure coding patterns. Returns actionable guidance with code examples.check_dependenciesCheck npm, PyPI, or Go packages for known security vulnerabilities (CVEs) using the OSV database. Use this before adding new dependencies or to audit existing ones.scan_directoryScan all files in a directory on disk for security vulnerabilities. Pass a directory path — reads files from filesystem. Returns security score (A-F) and findings. Results may be truncated for large projects — check fileRanking in JSON output for top files. Example: scan_directory({path: './src'})scan_dependenciesParse a lockfile or manifest (package.json, package-lock.json, requirements.txt, go.mod) and check all dependencies for known CVEs via the OSV database. Reads the file directly. Use this after installing dependencies, during CI, or when auditing existing projects for vulnerable packages.scan_hallucinated_packagesDetect AI-hallucinated and slopsquatted packages in a repo — the supply-chain seam commodity SCA misses. OFFLINE (deterministic): flags phantom imports (a package imported in source but absent from every package.json — a classic LLM hallucination tell) and typosquats of popular packages. ONLINE (opt-in, default on; gracefully degrades offline): adds npm-registry truth — packages that return 404 (definitive hallucination) and brand-new low-download packages (slopsquat-registration pattern). Run on AI-generated code at PR time, before `npm install`. Pass online:false for a fully deterministic, air-gapped scan.scan_secretsScan files and directories for leaked secrets, API keys, tokens, and credentials. Detects high-entropy strings, known API key patterns (AWS, Stripe, OpenAI, GitHub, Supabase), exposed .env files, and missing .gitignore coverage. Returns findings with exact line numbers and remediation steps.scan_stagedScan git-staged files for security vulnerabilities before committing. Run this before every commit to catch issues early. No input needed — automatically reads staged files. Diff-aware by default: reports only issues on newly-staged lines (set diff_aware:false for whole staged files).compliance_reportMap security findings to compliance controls (SOC2, PCI-DSS, HIPAA, GDPR, ISO27001, EUAIACT). Scans a directory and groups issues by control. Output includes a summary section at the top; for large projects, findings are truncated to top 50. Use mode=executive for C-level summary. Example: compliance_report({path: '.', framework: 'SOC2'})export_sarifScan a directory and export results in SARIF v2.1.0 format for CI/CD integration (GitHub, GitLab, Azure DevOps). Returns JSON string.check_package_healthCheck npm packages for typosquat risk, maintenance status, adoption metrics, and deprecation. Use this before adding new dependencies to catch suspicious or risky packages.- +27 more on the listing page

scf_list_controlsList SCF security controls from the reference catalog. Returns paginated controls with SCF ID, title, description, and mapped frameworks. Filter by domain, framework, or free-text search.scf_get_controlGet a single SCF control by ID. Returns description, mapped frameworks, assessment objectives, and linked evidence items from the reference catalog.scf_list_frameworksList every compliance framework mapped in the SCF catalog (NIST 800-53, ISO 27001, SOC 2, FedRAMP, GDPR, and 350+ more). Returns framework identifiers and display names.scf_list_domainsList every compliance domain in the SCF taxonomy. Domains group related controls (e.g., GOV = Governance, AST = Asset Management, IAC = Identity & Access Control).scf_list_evidence_catalogList evidence items from the SCF reference catalog — the 272 standard evidence types that can be collected to demonstrate control implementation. Supports free-text search and pagination.scf_list_assessment_objectivesList SCF assessment objectives — the 5,736 test criteria used to evaluate control implementation. Optionally filter by control ID; supports free-text search and pagination.scf_get_domainGet one SCF domain with its controls (read, no org). Deprecated controls are excluded unless include_deprecated is set; a deprecated domain still resolves, badged.scf_get_catalog_evidenceGet one catalog evidence entry with the controls it maps to (read, no org). The reference definition, not an organization's tracking record — see scf_get_evidence for that.scf_list_scoped_controlsList controls scoped to the organization with implementation status. Filter by scope status, domain, framework, CSF function, weighting, or free-text search. Paginated.scf_get_scoped_controlGet one scoped control in detail: owner, implementation notes, evidence links, and audit history. Identify by scf_id, not by UUID.scf_update_scoped_controlUpdate a scoped control's implementation fields (write — editor+ role). Identify by scf_id, not UUID. Only provided fields are applied.scf_get_scoping_statsGet the organization's implementation statistics: counts by status, overall completion percentage, and per-framework coverage breakdown.- +184 more on the listing page

Frequently asked questions
Guardvibe is categorized under Security and uses a local stdio subprocess. MCP Server Scf belongs to Security and uses a local stdio subprocess. Pick Guardvibe for security work and MCP Server Scf for security.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
Guardvibe is listed as free. Auth: no auth required. MCP Server Scf has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add goklab-guardvibe and mcp-server-scf as separate keys in the same mcpServers object, and your assistant will call tools from either one.
