mempalace（mempalace 搜索）

MemPalace — Local AI Memory System

You have access to a local memory palace via MCP tools. The palace stores verbatim conversation history and a temporal knowledge graph — all on the user's machine, zero cloud, zero API calls.

Architecture

• Wings = people or projects (e.g. wing_alice, wing_myproject)
• Halls = categories (facts, events, preferences, advice)
• Rooms = specific topics (e.g. chromadb-setup, riley-school)
• Drawers = individual memory chunks (verbatim text)
• Knowledge Graph = entity-relationship facts with time validity

Protocol — FOLLOW THIS EVERY SESSION

1. ON WAKE-UP: Call mempalace_status to load palace overview.
2. BEFORE RESPONDING about any person, project, or past event: call mempalace_search or mempalace_kg_query FIRST. Never guess from memory — verify from the palace.
3. IF UNSURE about a fact (name, age, relationship, preference): say "let me check" and query. Wrong is worse than slow.
4. AFTER EACH SESSION: Call mempalace_diary_write to record what happened, what you learned, what matters.
5. WHEN FACTS CHANGE: Call mempalace_kg_invalidate on the old fact, then mempalace_kg_add for the new one.

Available Tools

Search & Browse

• mempalace_search — Semantic search across all memories. Always start here.

- query (required): natural language search - wing: filter by wing - room: filter by room - limit: max results (default 5)

• mempalace_status — Palace overview: total drawers, wings, rooms
• mempalace_list_wings — All wings with drawer counts
• mempalace_list_rooms — Rooms within a wing
• mempalace_get_taxonomy — Full wing/room/count tree

Knowledge Graph (Temporal Facts)

• mempalace_kg_query — Query entity relationships. Supports time filtering.

- entity (required): e.g. "Max", "MyProject" - as_of: date filter (YYYY-MM-DD) — what was true at that time - direction: "outgoing", "incoming", or "both"

• mempalace_kg_add — Add a fact: subject -> predicate -> object

- subject, predicate, object (required) - valid_from: when this became true

• mempalace_kg_invalidate — Mark a fact as no longer true

- subject, predicate, object (required) - ended: when it stopped being true (default: today)

• mempalace_kg_timeline — Chronological story of an entity
• mempalace_kg_stats — Graph overview: entities, triples, relationship types

Palace Graph (Cross-Domain Connections)

• mempalace_traverse — Walk from a room, find connected ideas across wings

- start_room (required): room to start from - max_hops: connection depth (default 2)

• mempalace_find_tunnels — Rooms that bridge two wings
• mempalace_graph_stats — Graph connectivity overview

Write

• mempalace_add_drawer — Store verbatim content into a wing/room

- wing, room, content (required) - Checks for duplicates automatically

• mempalace_delete_drawer — Remove a drawer by ID
• mempalace_diary_write — Write a session diary entry

- agent_name (required): your name - entry (required): what happened, what you learned - topic: category tag

• mempalace_diary_read — Read recent diary entries

Setup

The user needs to initialize and populate the palace first:

pip install mempalace
mempalace init ~/my-convos
mempalace mine ~/my-convos

Then connect via MCP (for Claude Code, Cursor, etc.):

claude mcp add mempalace -- python -m mempalace.mcp_server

For OpenClaw, add to your MCP config:

{
  "mcpServers": {
    "mempalace": {
      "command": "python3",
      "args": ["-m", "mempalace.mcp_server"]
    }
  }
}

Tips

• Search is semantic (meaning-based), not keyword. "What did we discuss about database performance?" works better than "database".
• The knowledge graph stores typed relationships with time windows. Use it for facts about people and projects — it knows WHEN things were true.
• Diary entries accumulate across sessions. Write one at the end of each conversation to build continuity.
• Wings auto-detect from directory names during mining. You can also create custom wings via mempalace_add_drawer.
