How it works
From source code to actionable intelligence in four steps
From first touch to real results, without the guesswork.
Connect your repositories
CAST plugs directly into GitHub, BitBucket, and Azure DevOps to access source code and open-source components for analysis.
Run semantic analysis
CAST performs deterministic semantic analysis across 450+ technologies, mapping objects, dependencies, transactions, data flows, and architectural relationships.
Generate maps and dashboards
Results aggregate into interactive visual blueprints, call graphs, and portfolio-level dashboards covering quality, cloud maturity, technical debt, and AI readiness.
Ground AI agents with context
An MCP server exposes architectural context to MCP-compatible AI agents and development tools, complementing your existing AI workflows without replacing them.
Features
Deterministic intelligence across your entire portfolio
CAST analyzes source code semantically to produce maps, dashboards, and call graphs that executives, developers, and AI agents can act on.
Application architecture mapping
Reverse-engineer an entire application into an interactive visual blueprint showing code objects, data structures, dependencies, frameworks, and cross-application relationships.
Structural integrity gate
Detect system-level flaws affecting security, resiliency, and efficiency before changes reach production, applying ISO 5055 standards with recommended remediation paths.
Cloud maturity and blocker analysis
Identify the best candidates for cloud migration and surface blockers early, so modernization plans are grounded in facts rather than estimates.
AI and agentic readiness
Provide AI coding agents with application inventories, architectural graphs, call paths, and dependency maps through an MCP server delivered as a Docker container or Windows extension.
Software bill of materials management
Generate and manage SBOMs with open-source security and license risk detection across your portfolio. CAST SBOM Manager is available as a free download.
Portfolio governance dashboards
Aggregate results across applications into dashboards covering technical debt, quality grades, cloud maturity, green software impact, and work-effort metrics.
Evidence
Enterprises modernize faster with CAST

FAQ
Common questions about CAST and AI
What is AI + CAST?+
AI + CAST combines AI coding agents with deterministic software intelligence. CAST maps the architecture, dependencies, data access, call paths, and structural risks inside an application, then provides that context to AI agents so they can understand and transform complex software more accurately, efficiently, and safely.
Why can't an AI coding agent understand the application on its own?+
AI coding agents are effective at generating code but struggle to understand large, complex applications from source files alone. Important relationships may span multiple technologies, databases, repositories, and applications. CAST gives the agent a factual map of these relationships, reducing blind spots, incorrect assumptions, and unintended downstream impacts.
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, so the AI agent can ground its work in verified facts.
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 without introducing another tool to replace.
What development and modernization use cases can AI + CAST support?+
Common use cases include understanding unfamiliar applications, extracting business rules, performing change-impact analysis, generating documentation and tests, remediating technical debt, removing cloud blockers, identifying microservice candidates, replacing frameworks or databases, and transforming legacy applications.
