Summary

CoreStack v6.3 (2604) extends multi-cloud cost visibility and standards-based cost ingestion to a fourth major provider, Oracle Cloud Infrastructure (OCI), while deepening the FinOps controls teams rely on for commitment management and cost reporting. This release also consolidates CoreStack's AI tooling: CoreStack MCP moves to OAuth-based authentication and a single unified server, and can now be added as a custom connector in Claude and ChatGPT, or as a custom agent in Microsoft Copilot.

On the cost side, the Multi-Cloud Dashboard now shows OCI effective cost alongside AWS, Azure, and GCP, and FOCUS-aligned cost ingestion — previously AWS-only — is extended to Azure, GCP, and OCI. Rightsizing recommendations now check for existing RI and commitment coverage before firing, Savings Plan Utilization gains potential-savings and additional commitment metrics for AWS and Azure, budget alerts can route to Slack, and the Consolidated Charges Report now supports up to 20 Group By dimensions for MSP and Distributor reporting. On the platform side, SaaS account onboarding adds native storage support for Azure, GCP, and OCI, closing the last AWS-only gap in that workflow.

Together, these updates bring every supported cloud provider onto a common, standards-based cost model and extend CoreStack's agentic tooling into the AI assistants teams already use day to day.

FinOps

OCI Cost Dashboard — Effective Cost in Multi-Cloud Dashboard

Description: The Multi-Cloud Dashboard now includes Oracle Cloud Infrastructure (OCI) effective cost, bringing OCI to parity with the existing AWS, Azure, and GCP views within the same dashboard experience. OCI customers can now analyze spend side-by-side with other cloud providers without exporting data separately.

Key Capabilities:

Displays OCI effective cost within the existing Multi-Cloud Dashboard
Aligns OCI cost data alongside AWS, Azure, and GCP for side-by-side comparison

Key Benefits:

Extends single-pane-of-glass cost visibility to a fourth major cloud provider
Removes the need for OCI customers to track cost separately outside CoreStack

Supported Providers: OCI (shown alongside AWS, Azure, and GCP in the Multi-Cloud Dashboard)

Rule-Based Rightsizing — RI and Commitment Coverage Awareness

Description: Rightsizing and idle-resource recommendations now flag resources that are already covered under a Reserved Instance (RI) or other commitment, so teams don't receive rightsizing suggestions that conflict with existing commitment coverage.

Key Capabilities:

Cross-references rightsizing and idle-resource recommendations against active RI/commitment coverage
Flags commitment-covered resources before surfacing a rightsizing recommendation

Key Benefits:

Prevents rightsizing recommendations that would conflict with, or waste, existing RI/commitment coverage
Improves trust in recommendations by accounting for what's already committed

FOCUS-Based CUR Support Extended to Azure, GCP, and OCI

Description: CoreStack now ingests cost and usage data in the FOCUS (FinOps Open Cost and Usage Specification) format via Cost and Usage Reports (CUR) for Azure, Google Cloud Platform (GCP), and Oracle Cloud Infrastructure (OCI). This extends FOCUS-based cost ingestion — previously available only for AWS — to all four supported cloud providers, bringing every provider's cost data under a single, standards-aligned model.

Key Capabilities:

Ingests Azure, GCP, and OCI Cost and Usage Report (CUR) data in FOCUS-compliant format
Aligns Azure, GCP, and OCI cost data structures with CoreStack's broader FOCUS-based cost model
Extends FOCUS-standard ingestion, previously exclusive to AWS, across all remaining supported providers

Key Benefits:

Enables consistent, standards-based cost reporting across all supported cloud providers
Reduces custom mapping work for customers already using FOCUS for AWS cost data
Simplifies multi-cloud cost comparison and consolidated reporting under a single cost model

Supported Providers: All supported cloud providers (AWS, Azure, GCP, OCI)

Budget Management — Slack Notification Support

Description: Budget alerts can now be delivered to Slack via webhook, in addition to existing notification channels, giving teams the option to route budget threshold alerts directly into their Slack workspace.

Key Capabilities:

Sends budget alert notifications to Slack channels via webhook
Integrates with the existing Create and Manage Budgets workflow

Key Benefits:

Puts budget alerts directly in the team's existing Slack workflow instead of requiring a separate check-in
Reduces the chance of a missed budget alert by meeting teams where they already work

Current Savings Plan Utilization — Potential Savings and Additional Commitment Metrics

Description: The Current Savings Plan Utilization page for AWS and Azure now surfaces a fuller set of commitment metrics, including potential savings, alongside the existing utilization view. This gives FinOps teams a complete picture of savings plan performance without cross-referencing separate reports.

Key Capabilities:

Displays Total Commitment, Used Commitment, and Unused Commitment for each savings plan
Surfaces Net Savings and Potential Savings alongside existing utilization data
Shows On-Demand Cost Equivalent for comparison against committed pricing
Displays Region for EC2 Instance Savings Plans, where applicable

Key Benefits:

Gives FinOps teams a complete financial picture of savings plan performance in a single view
Surfaces unrealized (potential) savings so teams can identify further optimization opportunities
Extends the enhanced utilization view across both AWS and Azure savings plans

Supported Providers: AWS, Azure

Consolidated Charges Report — Expanded Group By Support

Description: The Consolidated Charges Report's Group By capability now supports up to 20 dimensions, up from a previous limit of 10. This gives Distributor and MSP partners deeper, multi-dimensional breakdowns of consolidated charges across complex, multi-level client hierarchies.

Key Capabilities:

Increases the maximum Group By dimensions in the Consolidated Charges Report from 10 to 20
Supports simultaneous multi-dimensional breakdowns across multi-cloud cost data

Key Benefits:

Enables more granular chargeback, showback, and profitability analysis across complex client hierarchies
Gives Distributor and MSP partners the multi-dimensional cost visibility needed for accurate multi-cloud reporting
Reduces the need to run multiple reports to capture all relevant cost dimensions

Platform

Multi-Cloud Storage Support for SaaS Account Onboarding

Description: This release extends the SaaS account onboarding wizard to support Azure Blob Storage, Google Cloud Storage, and OCI Object Storage alongside the existing AWS integration, giving customers on any major cloud platform a native path to configure their storage connection.

Key Capabilities:

Select your cloud storage provider: Choose AWS, Azure, GCP, or OCI during the SaaS account onboarding wizard.
Edit storage credentials post-onboarding: Update or switch cloud storage provider and credentials on any already-onboarded SaaS account, with a safety guard that preserves existing credentials if the new ones fail validation.

Key Benefits:

Unblock non-AWS customers entirely — organizations on Azure, GCP, or OCI can now complete SaaS account onboarding from start to finish without any AWS dependency
Reduce onboarding drop-off at the Storage Access step by presenting familiar, provider-native authentication flows that match what customers already use in their primary cloud platform
Protect live cost data during credential updates — the edit-flow safety guard ensures existing storage connections remain active until new credentials are successfully validated
