MegaMemory

What it does

MegaMemory allows coding agents to build and query a persistent knowledge graph of concepts, architecture, and decisions. Unlike static analysis, it lets the agent record its own understanding of a project in its own words, ensuring continuity and memory across different sessions.

Tools

• understand: Semantic search over the knowledge graph to find relevant concepts.
• get_concept: Retrieve full details for a specific concept by ID.
• create_concept: Add a new concept with optional edges and file references.
• update_concept: Update an existing concept's details and regenerate embeddings.
• link: Establish a typed relationship (e.g., depends_on, implements) between two concepts.
• remove_concept: Soft-delete a concept while preserving history.
• list_roots: List all top-level concepts to orient the agent.
• list_conflicts: Identify unresolved merge conflicts in the knowledge database.
• resolve_conflict: Resolve a merge conflict based on the current state of the codebase.
