MCP bridge for the Mnemo second brain — query your LightRAG-backed knowledge graph from Claude Code, Cursor, Cline, and other MCP-compatible AI tools.
Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"mnemo-brain-mcp","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.

# mnemo-brain-mcp MCP (Model Context Protocol) bridge to query your [Mnemo](https://github.com/komrxn/Khusayinbek_brain) second brain from **Claude Code**, **Cursor**, **Cline**, **Windsurf**, and any MCP-compatible AI tool. ## What is this? This is a friendly fork of [`desimpkins/daniel-lightrag-mcp`](https://github.com/desimpkins/daniel-lightrag-mcp). The protocol logic is identical; the package is renamed for one reason: a clean PyPI install for [Mnemo](https://github.com/komrxn/Khusayinbek_brain) users. If you're using a standalone LightRAG server (not Mnemo), the upstream package works fine — and you'll get upstream's updates faster. ## Install ```bash pip install mnemo-brain-mcp ``` After install the `mnemo-brain-mcp` command is on your `PATH`. ## Configure Point the bridge at your local LightRAG-API server (Mnemo runs it at `127.0.0.1:9621` by default): ### Claude Code Edit `~/.claude/claude_mcp_config.json` (or run `claude mcp add`): ```json { "mcpServers": { "mnemo-brain": { "command": "mnemo-brain-mcp", "env": { "LIGHTRAG_BASE_URL": "http://localhost:9621", "LIGHTRAG_API_KEY": "<paste contents of secrets/lightrag_api_key.txt>" } } } } ``` Restart Claude Code. Try: > *"What does my brain know about my current projects?"* ### Cursor `Settings → MCP → Add new MCP server`. Same JSON shape as above. ### Cline / Windsurf See their docs for the `mcpServers` config location — the JSON shape is the same. ## What this gives you 22 tools over MCP, including: | Tool | Purpose | | --- | --- | | `query_text` / `query_text_stream` | Hybrid semantic + graph search | | `get_knowledge_graph` | Subgraph around a label | | `get_graph_labels` | All entity labels | | `check_entity_exists` | Quick existence probe | | `get_documents` | List indexed sources | | `get_health` | Server health | | `insert_text` / `update_entity` / `delete_document` / ... | Write operations (be careful — see below) | For the full tool…
