tm42-mnemograph is a Claude Code plugin that adds a graph-based persistent memory MCP so sessions retain structured knowledge across restarts.
About
tm42-mnemograph is a Claude Code plugin that exposes mnemograph, a graph-based persistent yet lightweight memory MCP for coding agents. Developers tire of re-stating architecture, naming conventions, and past decisions at the start of every session; this bundle gives you a dedicated memory layer keyed to graph relationships instead of one long markdown file. The listing emphasizes persistent sessions, knowledge, and Claude integration—appropriate for agent-heavy workflows where continuity matters more than a single codegen task. Complexity sits at intermediate: you need MCP registration and comfort trusting an external memory graph. Use it journey-wide after the initial Build hookup whenever you iterate, support users, or prototype, because memory is not phase-locked. It complements skills and commands rather than replacing them: skills teach procedure, mnemograph remembers what already happened.
- Graph-based persistent memory MCP tailored for Claude Code sessions
- Lightweight knowledge store across sessions without bloating the main repo
- Category-tagged as memory with keywords: graph, persistent, sessions, knowledge
- Single-plugin bundle (plugin count: 1) focused on mnemograph semantics
- Fits builders who want structured recall rather than flat note dumps in CLAUDE.md

What it does
Install when you want Claude Code to remember project knowledge in a graph MCP across sessions without manually reloading context every time.
Who is it for?
Best when you're running many Claude Code sessions on one product and want durable, structured memory without building a custom vector database.
Skip if: Skip if you forbid external MCP memory, or projects where a static CLAUDE.md plus git history is enough.
What you get
After you register the MCP, your agent can read and write lightweight graph memory so project knowledge persists across sessions without repeating the full brief.
- Registered mnemograph MCP integration in Claude Code
- Persistent graph memory usable across agent sessions
- Reduced manual context pasting at session start

FAQ
Who is Tm42 Mnemograph for?
It is for Claude Code users who need cross-session memory—graph-linked facts and relationships—for ongoing product work.
When should I use Tm42 Mnemograph?
Use it when you start a new session and would otherwise paste long context, or when decisions and entities should accumulate over weeks of agent-assisted building.
How do I add Tm42 Mnemograph to my agent?
Install the plugin from tm42/mnemograph, enable the mnemograph MCP server in Claude Code settings, and verify the agent can query and update graph memory in a test session.
