Mymir: An Open-Source Project Graph for Coding Agents via MCP
A developer on r/ClaudeAI created Mymir, an open-source project management tool purpose-built for coding agents. It addresses the fragility of maintaining project state across agent runs — what's blocked, past decisions, implementation readiness, and handoff notes.
Core Idea
Tasks sit in a directed graph with dependencies, related decisions, acceptance criteria, relevant files, and previous execution notes. Through the Model Context Protocol (MCP), the agent receives only the slice of the project it needs — no full context dump or manual briefs.
Technical Stack
- Framework: Next.js
- Language: TypeScript
- Database: Postgres via Drizzle ORM
- License: AGPL (self-hosted)
How It Works
The team uses Mymir to manage itself. Features become tasks on the platform. Claude Code pulls scoped context for each session, and when a task is completed, the tool creates a structured handoff for the next session. The practical benefit: less re-explaining, fewer wrong starts.
