BarzelVault MCP - AI Action Firewall for Enterprise AI Agents

BarzelVault MCP is a production-grade Model Context Protocol server for securing AI agents before they take real-world actions. It works as an AI action firewall, governance gateway, approval layer, risk engine, audit system, and compliance companion for LLM tools that need to call APIs, write databases, manage files, trigger payments, operate admin systems, or touch sensitive business workflows.

Use BarzelVault when you need an MCP server for AI security, agent governance, policy enforcement, human approvals, compliance evidence, SOC 2 controls, GDPR data protection, prompt-injection defense, data-loss prevention, threat detection, incident response, and multi-tenant AI operations.

Marketplace capability coverage

The live MCPize discovery manifest exposes:

• 246 MCP tools for AI action firewalling, policy management, approvals, audit, compliance, assets, identity, anomalies, incidents, guardrails, execution control, observability, integrations, configuration, threat intelligence, and testing.
• 238 static MCP resources plus 109 resource templates for dashboards, action details, policies, approval queues, audit chains, compliance evidence, assets, tenants, incidents, metrics, sessions, integrations, configuration, threats, and test results.
• 277 MCP prompts for security reviews, risk analysis, approval recommendations, policy creation, compliance reporting, incident investigation, guardrail review, observability summaries, executive briefings, red-team evaluation, and customer-facing trust summaries.

Core features

• AI action firewall: evaluate, classify, simulate, block, allow, approve, sanitize, redact, and explain AI-requested actions.
• Policy governance: create policies, validate bundles, publish rules, compare versions, test policies, detect violations, and map policies to compliance controls.
• Human approval workflows: approval queues, multi-level approvals, delegation, escalation, reviewer comments, approval history, SLA summaries, and separation-of-duties checks.
• Tamper-evident audit: hash-chain audit events, signature verification, integrity checks, exportable logs, audit gap detection, and formal audit reports.
• Compliance reporting: SOC 2-style reports, GDPR summaries, ISO 27001-style control mapping, evidence collection, failed-control analysis, remediation plans, and executive compliance summaries.
• Asset governance: protect APIs, databases, payment systems, files, admin tools, critical workflows, owners, linked policies, risk profiles, and asset activity.
• Identity and tenant security: tenant context, RBAC, service accounts, API key lifecycle, permission checks, user access reviews, tenant isolation, and cross-tenant protection.
• Behavioral monitoring: anomaly detection, action bursts, privilege misuse, data exfiltration risk, financial risk patterns, baseline drift, and behavioral risk scores.
• Incident management: incident creation, timelines, linked evidence, containment actions, root cause analysis, response plans, and formal incident reports.
• Guardrails and data protection: PII scans, secret detection, sensitive-data classification, redaction, payload sanitization, consent checks, data deletion, export, and anonymization workflows.
• Execution resilience: circuit breakers, retry policies, queued actions, replay safety, paused routes, rate limits, failed-action recovery, and execution locks.
• Observability: metrics, traces, logs, latency, error summaries, policy metrics, approval metrics, risk distribution, tenant activity, agent activity, and dashboard summaries.
• MCP protocol operations: server health, tool manifest, resource manifest, prompt manifest, MCP sessions, protocol validation, session memory, and tenant-match checks.
• Integrations: webhook validation, webhook retries, Slack, email, Teams, SIEM, GRC, IAM, payment-provider, database, cloud-provider, and notification-channel management.
• Threat intelligence: threat scores, malicious payload analysis, prompt injection detection, command injection checks, SQL injection checks, SSRF detection, path traversal detection, IP reputation, domain reputation, and security review generation.
• Testing and evaluation: policy test suites, firewall simulations, regression tests, red-team scenarios, false-positive analysis, false-negative analysis, benchmark summaries, and production readiness reviews.
