Analysis Tools
30 codebase analyzers exposed to AI agents through the act MCP server — complexity, coupling, cycles, dead code, hotspots, structural boundaries, API surface, and migration readiness. The agent uses these to map a codebase before refactoring or porting it. See the Feature Matrix for tier details.
