BarzelVault MCP - AI Action Firewall for Enterprise AI Agents
BarzelVault MCP is a single, quality-optimized Model Context Protocol server for securing autonomous AI agents before they execute real-world actions. It is designed for AI action firewalling, LLM tool governance, human approvals, policy enforcement, audit integrity, compliance reporting, tenant isolation, threat detection, and production-grade AI agent operations.
Instead of exposing 246 narrow tools that overwhelm LLM tool selection, BarzelVault now exposes a focused 30-tool manifest. The original catalog functionality is preserved inside 18 domain controller tools through explicit operation enums, so agents get stronger discovery, lower latency, and better tool-calling accuracy without losing coverage.
Core features
- AI action firewall: request, evaluate, simulate, classify, allow, block, sanitize, redact, explain, approve, and execute AI actions.
- Policy governance: create, update, validate, publish, roll back, compare, test, and explain policy bundles.
- Approval workflows: pending queues, approvals, rejections, escalation, delegation, comments, history, SLA analysis, and separation-of-duties review.
- Audit integrity: tamper-evident audit logs, chain verification, signatures, gaps, exports, retention, and audit reports.
- Compliance reporting: SOC 2, GDPR, ISO 27001, evidence collection, control mapping, remediation, and executive summaries.
- Asset governance: APIs, databases, payments, files, admin tools, owners, risk profiles, policy links, and asset activity.
- Identity and tenant controls: RBAC, permissions, service accounts, API keys, tenant isolation, and privileged access review.
- Anomaly and incident response: behavioral risk, privilege misuse, data exfiltration risk, incident timelines, containment, and post-incident reports.
- Guardrails and data protection: PII scanning, secret detection, sensitive data classification, consent, deletion, export, and anonymization workflows.
- Observability, resilience, integrations, configuration, threat intelligence, testing, red-team evaluation, and business reporting.
Optimized MCP discovery manifest
- 30 MCP tools total: 12 production-backed tools plus 18 consolidated domain controllers.
- 25 static MCP resources for dashboards, actions, policies, approvals, audit, compliance, assets, identity, anomalies, incidents, guardrails, execution, observability, MCP protocol, integrations, configuration, threats, and testing.
- 17 MCP resource templates for action, policy, approval, audit, evidence, asset, tenant, anomaly, incident, trace, session, integration, threat review, and simulation detail pages.
- 21 MCP prompts: 18 comprehensive prompt families plus 3 compatibility prompts.
- Every discovered tool includes example_prompt and example_args.
- Every discovered resource and resource template includes examples.
- Every discovered prompt includes example arguments.
- Primary MCP transport is streamable_http JSON-RPC on /mcp. Legacy SSE endpoints remain only for backward compatibility.
