Drift
A codebase intelligence platform that detects patterns, conventions, and violations in code while maintaining memory across sessions. Exposes an MCP server with six entry points (drift_scan, drift_status, drift_tool, drift_discover, drift_workflow, drift_explain) that give AI agents access to ~70 specialized analysis utilities covering violations, security patterns, call graphs, architectural boundaries, coupling metrics, taint flows, and more. Includes a Cortex memory system for semantic memory, knowledge retrieval, and multi-agent coordination. Built with Rust (NAPI-RS bindings) and TypeScript for performance.
Best When
You have a medium-to-large codebase and want AI agents to understand deep structural patterns, enforce conventions, and maintain persistent codebase intelligence across sessions.
Avoid When
Your codebase is small or in a language not yet supported. The v2 rewrite is under active development, so expect some rough edges.
Use Cases
- • Giving AI coding agents deep codebase awareness beyond file contents
- • Detecting pattern violations and enforcing coding conventions via AI assistants
- • Security auditing codebases through OWASP findings and taint flow analysis
- • Understanding module coupling, API contracts, and architectural boundaries
- • Maintaining persistent codebase knowledge across multiple AI agent sessions
- • Monte Carlo simulation for change impact estimation
Not For
- • Replacing a full CI/CD linting pipeline (complementary, not a replacement)
- • Non-code analysis tasks
- • Very small or trivial codebases where the overhead is not justified
- • Languages not yet supported (currently Python, Java, PHP, TypeScript, C#)
