What it can access
- An MCP server is a program your AI app starts and talks to. A local one runs with your user's permissions: it can see the files, environment variables and network your account can.
- Based on its description and topics, it likely needs to connect to a database.
Before you install
- Give it a read-only database user unless it must write.
- Pin the version you reviewed instead of always installing the latest release.
- Read the tool list or scripts before the first run, and keep approval prompts on for actions that write, send or delete.
- Maintained by 0xK3vin on GitHub, 735 stars and 75 forks. Popularity is not proof of safety.
- Last code change: May 3, 2026.
- Open-source license: MIT.
Tools MegaMemory exposes (9)
Listed by the server itself during our scan of commit e0bb3c2.
understandQuery the project knowledge graph. Call this before starting any task to load relevant context about concepts, features, and architecture. Returns matched concepts with their children, edges, and parent context.
get_conceptLook up a concept by its exact ID. Returns the concept with its full context including children, edges, incoming edges, and parent. Unlike 'understand' which uses semantic search, this does exact ID matching. Use this when you know the specific concept ID.
create_conceptAdd a new concept to the knowledge graph. Call this after completing a task to record new features, components, patterns, or decisions you built. Include specific details: parameter names, defaults, file locations, and rationale.
update_conceptUpdate an existing concept in the knowledge graph. Call this after completing a task that changed existing features or components. Only include fields that changed.
linkCreate a relationship between two existing concepts.
remove_conceptSoft-delete a concept from the knowledge graph. The concept and its removal reason are preserved in history.
list_rootsList all top-level concepts in the knowledge graph with their direct children. Call this at the start of a session to get a high-level project overview.
list_conflictsList all unresolved merge conflicts in the knowledge graph, grouped by merge_group. Each group contains competing versions with full data. Call this when the user runs /merge to begin AI-assisted conflict resolution.
resolve_conflictResolve a merge conflict by providing the correct resolved content. Read both conflict versions, verify against the current codebase, then provide the accurate resolved summary. Do NOT just pick a side — write the truth.
