# memex-md-mcp *You like Obsidian? Your LLM will love it too.* *[Memex](https://en.wikipedia.org/wiki/Memex): Vannevar Bush's 1945 concept of a "memory extender" - a device for storing and retrieving personal knowledge. The conceptual ancestor of personal wikis and second brains.* MCP server for searching and navigating markdown vaults. Point it at your Obsidian vault (or any markdown folder) and get semantic search, wikilink/backlink traversal, and note renaming with automatic link updates. **What memex is:** A search and navigation layer over your markdown files. SQLite with FTS5 for keyword search, [embeddinggemma](https://huggingface.co/google/embeddinggemma-300m) for semantic similarity, wikilink graph for backlinks. **What memex isn't:** An automatic memory system. It won't capture context or write notes for you. For that, check out [claude-mem](https://github.com/thedotmack/claude-mem) (automatic memory compression with hooks and summaries). Memex pairs well with workflow layers on top—see [my agent workflows](https://github.com/MaxWolf-01/agents) for an example using memex as the knowledge backend. ## Quick Start ```bash claude mcp add memex -- uvx --from 'memex-md-mcp==1.*' memex-md-mcp ``` Then ask Claude to help configure your vaults - it has `mcp_info()` which explains everything. Or manually edit your settings (see Configuration below). **Version note:** The above pins to the latest 1.x release for stability. For bleeding edge, use `memex-md-mcp@latest`—but watch the repo for releases, since major bumps may require deleting your index (`~/.local/share/memex-md-mcp/memex.db`). ## What This Does Memex gives Claude read access to your markdown vaults. It creates a local index at `~/.local/share/memex-md-mcp/memex.db` and logs to `~/.local/share/memex-md-mcp/memex.log`. The index contains: - Full-text search index (FTS5) for keyword matching - Embeddings (google/embeddinggemma-300m) for semantic similarity - Wikilink graph for backlink queries …
