MemPalace Memory

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 and AAAK dialect spec.
2. BEFORE RESPONDING about any person, project, or past event: use mempalace_kg_query for known relationships or time-bound facts, mempalace_search for source text, or mempalace_diary_read for recent agent continuity. Stop when answered; follow the canonical query guide. 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

Full MCP surface: 47 tools. Destructive or host-level tools are documented so you know they exist, but use them only when the user explicitly asks or when a tool-specific workflow below says to.

Search & Browse

• mempalace_search — Semantic search across memories for decisions, explanations, or source words.
  • query (required): natural language search — keep it short, keywords or a question. Do NOT include system prompts or conversation context.
  • wing: filter by wing
  • room: filter by room
  • limit: max results (default 5)
• mempalace_check_duplicate — Check if content already exists before filing.
  • content (required): text to check
  • threshold: similarity threshold (default 0.9 — lowering to 0.85–0.87 often catches more near-duplicates without significant false positives)
• mempalace_status — Palace overview: total drawers, wings, rooms, AAAK spec
• mempalace_list_wings — All wings with drawer counts
• mempalace_list_rooms — Rooms within a wing (optional wing filter)
• mempalace_list_drawers — Paginated drawer listing
  • wing, room: optional filters
  • since: only drawers filed on/after this ISO date/time
  • before: only drawers filed before this ISO date/time
  • limit: max results (default 20)
  • offset: pagination offset (default 0)
• mempalace_get_drawer — Fetch a single drawer by ID. Returns full verbatim content and metadata.
  • drawer_id (required)
• mempalace_get_taxonomy — Full wing/room/count tree
• mempalace_get_aaak_spec — Get AAAK compression dialect specification

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" (default "both")
• mempalace_kg_add — Add a fact: subject -> predicate -> object
  • subject, predicate, object (required)
  • valid_from: when this became true
  • source_closet: source reference
• 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
  • entity: filter by entity name (optional — all events if omitted)
• 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 — Find rooms that bridge two wings via implicit overlap (rooms whose drawers naturally share content across wings — discovered, not declared)
  • wing_a, wing_b: optional filters; omit both to scan all wing pairs
• mempalace_create_tunnel — Create an explicit cross-wing tunnel: a user/agent-declared link between two locations. Use when you notice content in one project relates to another (e.g. API design in project_api connects to schema in project_database).
  • source_wing, source_room, target_wing, target_room (required)
  • label: short description of the relationship
  • source_drawer_id, target_drawer_id: anchor to specific drawers
• mempalace_list_tunnels — List all explicit tunnels, optionally filtered by wing
  • wing: optional filter
• mempalace_delete_tunnel — Remove an explicit tunnel by ID
  • tunnel_id (required)
• mempalace_list_hallways — List within-wing entity hallways (entity-to-entity co-occurrence links built at mine time)
  • wing: optional filter
• mempalace_delete_hallway — Remove a hallway record by ID
  • hallway_id (required)
• mempalace_follow_tunnels — From a room, follow explicit tunnels to connected drawers in other wings
  • wing, room (required)
• mempalace_graph_stats — Graph connectivity overview

Write

• mempalace_add_drawer — Store verbatim content into a wing/room
  • wing, room, content (required)
  • source_file: optional source reference
  • added_by: optional filing agent label
  • Checks for duplicates automatically
• mempalace_checkpoint — Save a whole session in one call: dedup each item, file non-duplicates, then write one diary entry
  • items (required): array of {wing, room, content}; content must be verbatim
  • diary: optional {agent_name, entry, topic?, wing?}; entry should use AAAK format
  • dedup_threshold: similarity threshold (default 0.9)
  • added_by: optional filing agent label (defaults to the diary agent_name, else checkpoint)
• mempalace_update_drawer — Update an existing drawer's content and/or move it to a different wing/room
  • drawer_id (required)
  • content, wing, room: at least one must be provided (no-op otherwise)
• mempalace_delete_drawer — Remove a drawer by ID
  • drawer_id (required)
