About Vanta MCP Server
Connect your Vanta account to any AI agent and bring continuous security monitoring directly into your conversational workflow.
LangChain's ecosystem of 500+ components combines seamlessly with Vanta through native MCP adapters. Connect 10 tools via Vinkius and use ReAct agents, Plan-and-Execute strategies, or custom agent architectures. with LangSmith tracing giving full visibility into every tool call, latency, and token cost.
What you can do
- Personnel Compliance — Rapidly list all active personnel records, fetch specific user security training completion details, or deactivate users directly during employee offboarding.
- Endpoint Fleet — Retrieve data on all computers and physical workstations actively monitored by Vanta, ensuring disk encryption and antivirus SLA compliance.
- Vulnerability Tracking — Monitor unpatched Common Vulnerabilities and Exposures (CVEs) across your cloud infrastructure and verify remediation SLAs in real-time.
- Security Posture — Access public Trust Center configurations, review pending security report requests from customers, and list your internal risk-vetted third-party vendors (subprocessors).
The Vanta MCP Server exposes 10 tools through the Vinkius. Connect it to LangChain in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

Vanta MCP Tools for LangChain (10)
These 10 tools become available when you connect Vanta to LangChain via MCP:
vanta_compliance_status
Shows: overall pass rate percentage, number of passing/failing/warning tests per framework, critical alerts requiring immediate attention, and the audit-readiness score. Use when the user asks "how is our compliance?", "are we ready for the SOC 2 audit?", or needs a quick compliance health check across all frameworks. Get the overall compliance posture dashboard — pass rates per framework, critical alerts, and audit readiness score across SOC 2, ISO 27001, HIPAA, and GDPR
vanta_get_test
Use to drill into a failing test: "why is the MFA test failing?" or "which resources are non-compliant for encryption?" Get detailed information about a specific Vanta compliance test — evidence, linked controls, failing resources, and remediation guidance
vanta_list_computers
Each device shows: device name, OS version, disk encryption status, firewall enabled, antivirus installed, screen lock configured, owner email, and overall compliance status. Use for endpoint compliance audits, device inventory, or identifying non-compliant machines before an audit. List monitored endpoint devices — laptops and desktops with OS version, encryption status, antivirus, and compliance state
vanta_list_evidence_requests
Each request includes: description of the evidence needed, assigned owner, due date, completion status, and linked control. Use during audit preparation: "what evidence is still outstanding?", "who needs to submit screenshots?", or "are we ready for the audit?" List outstanding audit evidence requests in Vanta — documents and screenshots needed from team members with deadlines
vanta_list_integrations
). Each integration shows: service name, connection status (connected/disconnected/error), last sync date, coverage metrics, and any configuration warnings. Use to check integration health, verify coverage, or troubleshoot sync issues. List all connected integrations in Vanta — cloud providers, identity providers, code repos, and their sync status
vanta_list_people
Each person includes: name, email, role, security awareness training status (completed/overdue), device compliance (encrypted/antivirus/updated), access review completion, and employment status. Use for "who has overdue training?", "which employees have non-compliant devices?", or pre-audit personnel reporting. List all personnel in Vanta with security training completion, device compliance, access review status, and onboarding/offboarding state
vanta_list_policies
). Each policy shows: name, approval status (approved/draft/needs review), last review date, next review due, version number, and percentage of employees who have acknowledged. Use for policy management audits or compliance gap analysis. List all security and compliance policies in Vanta — approval status, review dates, version tracking, and employee acknowledgment rates
vanta_list_risks
Each risk includes: title, description, risk category, impact level (1-5), likelihood level (1-5), calculated risk score, linked mitigating controls, treatment plan (accept/mitigate/transfer), owner, and status. Use for risk management reporting, board-level summaries, or identifying high-risk areas that need attention. List the risk register — identified security risks with impact, likelihood, risk score, assigned controls, and mitigation status
vanta_list_tests
Each test maps to a specific control requirement (e.g., "MFA enabled for all users", "Encryption at rest"). Returns test name, associated framework (SOC 2/ISO/HIPAA/GDPR), current status (PASS/FAIL/WARNING), last run date, and any remediation notes. Use when the user asks about compliance posture, failing tests, or audit readiness. List all compliance monitoring tests in Vanta — SOC 2, ISO 27001, HIPAA, and GDPR controls with pass/fail status and last run dates
vanta_list_vulnerabilities
). Each entry includes severity (CRITICAL/HIGH/MEDIUM/LOW), CVE identifier, affected resource/package, discovery date, and SLA deadline for remediation. Use when the user asks about security posture, open vulnerabilities, or needs to prioritize remediation work. List detected security vulnerabilities across your infrastructure — severity, CVE IDs, affected resources, and SLA deadlines
