CSA Assessment Reports Server

An MCP (Model Context Protocol) server that gives Bob AI direct access to Cloudability Savings Automation (CSA) assessment reports stored in SharePoint. Sales and CSA teams can create pitch decks, analyze savings projections, and compare coverage—all through natural language.

What It Does

Instead of manually navigating SharePoint, downloading Excel files, and extracting data across 49 sheets, users simply ask Bob:

"Create a pitch deck for Apptio with 24-month savings projection"

Bob uses this MCP server to fetch, process, and return structured data in seconds.

SharePoint Data Layout

Assessment reports are distributed across 4 SharePoint sites. The primary site holds master reports (consolidated portfolio data), while the other 3 sites share the volume of individual assessment reports across all organizations and payer accounts.

    style S4 fill:#4a9eff,color:#fff

Each assessment report is an Excel file with 49 sheets containing compute usage, savings plans, reserved instances, planning models, and projections. Reports are split across 3 sites to manage SharePoint's file volume limits.

Business Value

Time Comparison: Manual vs Bob-Assisted

Step	Manual	With Bob
Find the right report	8-18 min (navigate SharePoint, guess which site)	10 sec (parallel search across all sites)
Download & open file	7 min (50-100MB Excel)	30 sec (server-side download, cached after first access)
Locate data in 49 sheets	10-15 min	15 sec (structured extraction)
Extract & format metrics	15-20 min	15 sec
Create deliverable	10-15 min	60 sec (LLM streaming + file generation)
Total	30-70 min	~2-3 min

Architecture

The project uses a two-service architecture to resolve Pydantic v1/v2 dependency conflicts:

Bob Integration

This MCP server integrates with Bob (IBM's AI assistant) to provide natural language access to CSA assessment data. Bob uses a dedicated skill (csa-assessments-analyzer) that connects to this MCP server and automates the full workflow from data retrieval to deliverable generation.

Deployment

# Prerequisites: AWS credentials, CodeArtifact access

# 1. Prepare dependencies (Linux ARM64 wheels)
./scripts/prepare-deployment.sh

# 2. Build and push MCP server container
./scripts/build-and-push-ecr.sh

# 3. Deploy with Serverless Framework
serverless deploy --stage dev1 --region us-west-2

# 4. Force ECS task to pull latest image
aws ecs update-service \
  --cluster csa-assessments-mcp-dev1-cluster \
  --service csa-assessments-mcp-dev1-mcp-service \
  --force-new-deployment

Endpoints

After deployment:

• Backend API: https://<rest-api-id>.execute-api.us-west-2.amazonaws.com/<stage>/api/health
• MCP Server: https://<http-api-id>.execute-api.us-west-2.amazonaws.com/mcp

Multi-Site SharePoint Architecture

The backend dynamically routes requests across 4 SharePoint sites:

    BE -->|Master Reports| S1[Site 1: CSAReporting<br/>Portfolio-wide data]
    BE -->|Parallel Search| S2[Site 2: CSAReporting 2<br/>About one-third of assessment reports]
    BE -->|Parallel Search| S3[Site 3: CSAReporting 3<br/>About one-third of assessment reports]
    BE -->|Parallel Search| S4[Site 4: CSAReporting 4<br/>About one-third of assessment reports]

    style S2 fill:#4a9eff,color:#fff
    style S3 fill:#4a9eff,color:#fff
    style S4 fill:#4a9eff,color:#fff

• Users don't need to know which site holds their data
• Parallel queries across all 3 assessment sites
• Reports distributed across sites to manage SharePoint file volume limits
• Automatic caching with 4-hour TTL
• Resilient — if one site is unavailable, others continue working

Local Development
