Legacy System and Enterprise API Integration
Bridging modern generative AI and agentic capabilities with core legacy systems of record (SAP, Oracle, AS400, mainframe) securely.
Practice Overview
Enterprise AI creates value only when deeply embedded in existing systems of record: ERPs, CRMs, core banking platforms, and manufacturing execution systems (MES). Standalone web portals are ignored; intelligence must live where work happens. TRUSTGRID.AI builds secure, bidirectional integration fabrics: deploying modern REST/gRPC wrappers, message queues, Model Context Protocol (MCP) servers, and transactional guardrails that connect autonomous AI agents directly to SAP, Oracle, Salesforce, and legacy mainframes.
Enterprise Challenges Addressed
Brittle, undocumented legacy APIs and proprietary mainframe protocols resisting modern AI integration.
Risk of catastrophic data corruption if autonomous AI agents execute unvalidated write operations.
Severe impedance mismatch between modern asynchronous streaming LLMs and synchronous transactional ERPs.
Rigid security policies preventing direct external internet access from on-premise core databases.
Implementation Approach & Methodology
Non-Invasive Adapter Layer: Building secure proxy middleware and MCP servers that expose legacy functions cleanly.
Transactional Idempotency & Staging: Staging AI-generated transactions in verification queues before committing writes.
Bidirectional Event Synchronization: Using Change Data Capture (CDC) to stream legacy updates into AI context stores.
Strict Zero-Trust Boundary: Enforcing granular mTLS, RBAC, and executive approval gates for high-value actions.
Reference Architecture & Delivery Workflow
Secure Legacy Enterprise AI Integration Gateway
Zero-trust gateway translating autonomous agent actions into audited transactional writes in core ERP systems.
Agent Action Request
Autonomous agent initiates tool call via standardized Model Context Protocol (MCP).
Policy & RBAC Validation
Inspect user permissions, spend thresholds, and action criticality.
Staging & Human Approval
Route actions exceeding risk thresholds to human-in-the-loop verification dashboard.
Legacy Transaction Execution
Commit write to SAP BAPI / Oracle database via transactional two-phase commit.
