Executive Summary // Architecture Brief
PRODUCTION SPECIFICATIONA production-hardened Microsoft 365 AI integration and automation system. Connects Microsoft Graph API to Claude Enterprise via secure Python MCP middleware, orchestrating a 10-stage closed loop: from meeting voice capture and transcript parsing to role-assigned task distribution and executive Power BI forecasting.
Across three consecutive production engagements, SHIVAM ITCS designed, built, and delivered Microsoft 365 intelligence systems that convert everyday business activity — meetings, notes, decisions — into structured intelligence, role-based action, and compounding institutional memory. From deploying Claude Enterprise across financial services firms via custom Python MCP servers to configuring four-team structured M365 workspaces and automating daily Teams meeting intelligence with role-based task distribution, our architecture enforces 100% tenant data sovereignty. Content never leaves the customer Microsoft boundary, secrets reside in Azure Key Vault, and access follows the principle of least privilege.

Zero Data Leakage Sovereignty
Preview URLs via Graph keep content inside the customer tenant; secrets stored in Azure Key Vault.
Executive Architecture: The M365 Intelligence Loop
Core Capabilities & Production Guarantees
- Deep Microsoft Graph API integration across OneNote, call records, transcripts, DriveItem, and calendar events
- Centralized Python MCP middleware hosted on Azure VM with individual OAuth 2.0 credential resolution
- Role-based intelligence routing: junior members get role tasks, while leadership receives predictive forecasting
- Strict data residency: content stays 100% inside your tenant with Graph preview URLs and Azure Key Vault isolation
- Production resilience: idempotency, per-item isolation, 429 exponential backoff, dead-letter logging, and DST-aware cron
The M365 Intelligence Loop & Claude Enterprise Topology
Sovereign Graph API pipelines, centralized Python MCP middleware on Azure VM, and role-based action routing with zero tenant data leakage.
Capture StageMULTIMODAL INGESTION
Enumerates completed Teams meetings, OneNote notebooks across users, and Outlook calendar events via Microsoft Graph API.
GET /communications/callRecordsGET /users/{id}/onenote/notebooksGET /me/eventsRequires Graph application scopes with tight time windows and joinWebUrl mapping.
Recurring meetings share identical titles; indexing on title causes collisions. Canonical ID must be the Graph call record ID.

Verified Production Impact & Client Endorsements
Real feedback from engineering leaders, CTOs, and founders across 15+ years of production deployments.
“Vijay and the SHIVAM ITCS AI team didn't just execute the project - they elevated our entire platform. Their ability to architect complex multi-agent state machines, eliminate latency bottlenecks, enforce zero-hallucination guardrails, and create an intelligent multi-LLM orchestration layer was extraordinary. The final delivery was resilient, battle-tested, and far beyond expectations. One of the strongest AI systems engineering teams in the industry.”
