The toolkit
Everything you need to move fast with confidence
From portfolio-level governance to line-level detail, CAST gives you the facts to decide and act quickly.
Portfolio governance dashboards
Compare applications across technical debt, cloud maturity, open-source risk, and AI readiness in one view.
AI agent context via MCP
Feed deterministic architectural facts to MCP-compatible AI coding agents so they understand complex systems before making changes.
Structural integrity gates
Block system-level flaws from reaching production using ISO 5055 rules with recommended remediation paths.
Cloud readiness scoring
Identify migration candidates and flag blockers before you commit to a cloud move, saving rework and budget.
SBOM management
Generate and manage software bills of materials with open-source security and license risk detection.
The case for change
You cannot modernize what you cannot see
Most teams spend months in manual discovery before writing a single line of new code. CAST compresses that timeline dramatically.
The old way
- ×Months of manual code review before modernization can begin
- ×AI coding agents guess at architecture and miss cross-system dependencies
- ×Technical debt grows unchecked because no one can pinpoint where it hurts most
- ×Cloud migration stalls on hidden blockers discovered late in the process
With CAST
- ✓Semantic analysis maps an entire application into an interactive blueprint in hours
- ✓AI agents receive deterministic architectural context via MCP, reducing rework and risk
- ✓ISO 5055-based scoring identifies the 8% of code causing 90% of production issues
- ✓Cloud readiness scores flag blockers before migration starts, not after
Step by step
From source code to actionable intelligence in three steps
A clear path from first step to measurable outcome.
Connect your repositories
CAST plugs directly into GitHub, BitBucket, Azure DevOps, or local codebases. No manual tagging or configuration required.
CAST analyzes semantically
The engine parses 450+ technologies, mapping objects, dependencies, transactions, data flows, and architectural relationships deterministically.
Teams and AI agents act on facts
Dashboards, interactive maps, and MCP-served context give developers, executives, and AI tools the verified intelligence to move quickly.

Answers
Common questions about CAST
What does deterministic software intelligence mean?+
The information is derived through semantic analysis of the actual software rather than inferred or generated probabilistically by an LLM. CAST identifies the application's real objects, dependencies, transactions, data flows, and architectural relationships.
Does CAST replace our existing AI coding tools?+
No. CAST complements the AI tools you have already selected. It supplies deterministic application context to MCP-compatible agents and development tools, improving your existing AI-enabled workflows without introducing another tool to replace.
What kinds of use cases does AI + CAST support?+
Understanding unfamiliar applications, extracting business rules, change-impact analysis, generating documentation and tests, remediating technical debt, removing cloud blockers, identifying microservice candidates, replacing frameworks or databases, and transforming legacy applications.
How is CAST Highlight priced?+
Annual subscriptions range from $20,000 for 25 applications to $240,000 for 1,000 applications, regardless of the number of developers. Each portfolio requires its own subscription. Three editions are available: Complete Insights, Cloud Insights, and SCA Insights.
Can CAST deploy on-premises?+
Yes. CAST offers both SaaS and on-premises deployment. The MCP server is delivered as a Docker container or Windows extension.
