Mneme Decision MCP

Architectural drift prevention for the agentic AI SDLC. Mneme turns architectural decisions and ADRs into deterministic guardrails for the agentic AI SDLC - across coding agents, repository mutations, generated rules, and CI gates. It runs locally over stdio via the published package.

People who work with ai coding, developer tools and software architecture and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.
