The toolkit
Govern software portfolios with empirical facts
CAST provides a deterministic MRI for your software, identifying critical flaws, cloud blockers, and AI readiness.
Structural Integrity Gates
CAST Gatekeeper analyzes semantics, applies ISO 5055 rules, and recommends remediation paths to block system-level flaws before production.
Deterministic Software Intelligence
Semantic analysis of source code identifies real objects, dependencies, transactions, and data flows across 450+ technologies.
AI Agent Context
The MCP server provides AI agents with factual architectural context, reducing blind spots and unintended downstream impacts.
Cloud & Tech Debt Analysis
Identify best candidates for cloud migration, pinpoint technical debt, and detect open source security and license risks.
The shift
Stop guessing about your software architecture
Large applications hide critical dependencies and structural flaws. AI agents struggle to understand them from source files alone, leading to unintended downstream impacts.
The old way
- ×Blind spots across multiple technologies, databases, and repositories
- ×AI coding agents make incorrect assumptions about complex systems
- ×System-level flaws affecting security and resiliency reach production
The CAST way
- ✓Deterministic semantic analysis maps real objects, dependencies, and data flows
- ✓Provides AI agents with factual architectural context to reduce rework
- ✓Structural integrity gates apply ISO 5055 rules to block flaws before production
Getting started
From source code to actionable intelligence
A simple route from setup to steady output.
Connect your repositories
CAST plugs directly into source code repositories like GitHub, BitBucket, and Azure DevOps to analyze open-source components.
Run semantic analysis
CAST performs a deterministic MRI for software, mapping internal structures, dependencies, and cross-application relationships.
Block flaws and guide AI
Use structural integrity gates to stop flaws before production and provide AI agents with verified architectural context.

Frequently asked questions
What does deterministic software intelligence mean?+
It means 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 or agents?+
No. CAST complements the AI tools an organization has already selected. It supplies deterministic application context to MCP-compatible agents and development tools, allowing customers to improve their existing AI-enabled workflows.
What kinds of software intelligence does CAST provide to AI agents?+
CAST provides application inventories and statistics, internal architectural graphs, cross-application dependencies, transactions, data-access paths, call graphs, object details, source-code locations, and direct and indirect dependencies.
