Every tool solves this in its own silo — a rules file here, a memory feature there — but you are the constant. One SQLite file that any MCP client can read means the decisions you made last week survive changing which assistant you use this year.
A memory layer that runs over a local SQLite file and speaks MCP, so Claude Desktop, Claude Code, Cursor, Copilot, Cline, OpenCode, Aider or a custom agent all read and write the same durable, structured memories about you and your work. Local-first, with no outbound network calls by default.
- 38 tools, named `verb_noun` — every registry command whose surfaces include MCP
- Reading — `search_memory`, `read_memory`, `list_memories`, `get_memory_context`, `list_memory_events`
- Writing — `write_memory`, `write_many_memories`, `update_memory`, `supersede_memory`, `extract_memory`
- Curating — `confirm_memory` and `confirm_many_memories` to keep a memory alive, `archive_memory`, `forget_memory`, `restore_memory`, and the bulk forms, which require `confirm: true` and preview by default
- Housekeeping — `run_compact` archives cold memories whose confidence has decayed past the threshold, `rebuild_embeddings`, `set_memory_embedding`
- Conflicts — `scan_conflicts`, `list_conflicts`, `read_conflict`, `resolve_conflict`, `list_conflict_events`
- Packs — `install_pack`, `preview_pack`, `list_packs`, `export_pack`, `uninstall_pack`, so a curated set of memories can be shared as a file or a URL
- Configuration and system — `get_config`, `set_config`, `unset_config`, `list_config`, `list_config_history`, `info_system`, `list_scopes_system`, `list_tags_system`
Node.js 22.11+. Run `npx @psraghuveer/memento init`, which creates the database under `$XDG_DATA_HOME/memento/memento.db`, runs migrations, and on a terminal asks four setup questions — your preferred name, whether to install the bundled skill, whether to seed a starter pack, and whether to write the persona snippet into the custom-instructions file of each AI client it detects. It then prints the MCP snippet for every supported client; restart the client after pasting it. The persona snippet matters: of the three teaching surfaces, it is the only one guaranteed to reach the assistant's system prompt on every message, so UI-only clients need it pasted by hand. Verify the whole path with `npx @psraghuveer/memento verify-setup`, which does a write, search and cleanup round-trip.
One command — npx @psraghuveer/memento init
