Governed DAB Control Plane for Data & AI APIs.
The governance and release-workflow layer for Data API Builder. Visually design entities, simulate zero-trust ABAC claims, export authorized MCP tools for AI agents, and emit production-ready dab-config.json manifests with active cache preservation.

The 6 Core Pillars of Meynos
Everything platform teams, CISOs, and data architects need to manage enterprise Data API Builder releases.
1. Visual Schema & Entity Designer
Import schemas from SQL Server, Azure SQL, Postgres, and Fabric. Visually define entities, fields, relationships, and action bindings without writing manual JSON configurations.
2. Identity Impersonation Simulator
Visually define tenant, user, and role claims—then preview the exact rows, columns, and MCP tools each identity sees. Validate access before deploying to production.
3. DAB Config Generator & Policy Injector
Emits production-ready dab-config.json with database policies and @authorize directives baked in while preserving sub-20ms response caching.
4. Tool-Level MCP Allow/Deny Exporter
Solves DAB's real gap: Cosmos DB lacks native database policies, and there is no unified per-tool ABAC. Meynos generates fine-grained tool allow/deny schemas for Claude, OpenAI, and Cursor.
5. Unified Multi-Engine Audit Stream
Logs every REST, GraphQL, and MCP tool call with actor identity, tool/entity, operation, policy applied, and result. Stream directly to Azure Monitor, Splunk, or Datadog for SOC2/HIPAA compliance.
6. Light Schema-Drift Detection
Continuously compares upstream database DDL against deployed configs. Automatically detects added/dropped columns, renames, and type changes to keep DAB manifests perfectly in sync.
Why Platform Teams Need a Governed DAB Control Plane
Microsoft Data API Builder (DAB) is an incredible high-performance engine for turning databases into REST and GraphQL endpoints. However, enterprise adoption requires solving three major gaps:
Enabling session-based RLS (sp_set_session_context) turns off DAB's L1/L2 response caching, causing massive database compute spikes and 10x latency.
Cosmos DB has no native database policies, and DAB lacks tool-level allow/deny authorization for AI agent MCP servers.
Meynos compiles static zero-trust views with active caching, exports secure MCP tools, and streams unified compliance audits.
