เอกสารประกอบ delx-memory
Local-first persistent memory MCP server. One shared SQLite store any MCP-speaking agent (Claude Desktop, Cursor, Hermes, OpenClaw, Codex) can read and write — so context survives across sessions AND across tools.
Local-first persistent memory MCP: shared SQLite key/value store, searchable, TTL-aware, secret-safe

Why Every chat client has its own ephemeral context. Quit the tab → preferences gone. Switch from Claude Desktop to Cursor → starting from scratch. Pin a side project in Hermes → invisible to the next agent.
delx-memory is a tiny MCP server that exposes a single shared SQLite file as a key/value memory layer. Any client that speaks MCP can read and write the same memory file → real continuity, real cross-tool context.
15 tools — discovery + handoff + batch ops + FTS5 search + mutations gated by intent.SQLite at ~/.delx-memory/db.sqlite (0700 dir, 0600 file).
Secret-blocking : refuses to store credential-shaped keys or values.TTL support (lazy expiry on read).
Tags + prefix filters + FTS5 full-text search (bm25 ranking, stemming, diacritic folding; LIKE fallback if FTS5 is unavailable).
Mutations require explicit_user_intent: true so over-eager agents can't silently rewrite your context.
Zero telemetry. Zero phone-home. The file is yours.
Multi-agent namespaces # Agent A
DELX_MEMORY_NAMESPACE=claude npx -y delx-memory
# Agent B (same machine, isolated keys)
DELX_MEMORY_NAMESPACE=cursor npx -y delx-memory
Keys are stored as namespace::key. Omit the env var for a single global store (default).
Footprint / lightweight mode
Default transport is lite : tools-only MCP over stdio without loading the MCP SDK (biggest RSS win for always-on agents).Full SDK surface (prompts + resources): delx-memory --sdk or DELX_MEMORY_TRANSPORT=sdk.
Optional HTTP: delx-memory --http (Express + SDK; still loopback by default).
DELX_MEMORY_LEAN=1 applies to the SDK path only (skip prompts/resources).doctor --json reports rss_kb. Dominant remaining cost is Node + native better-sqlite3 (no embeddings). Community measurements (custom transport vs SDK) pointed at the SDK tree as the main overhead — see issue #7.
Install + run # Run once (npx will download + boot)
npx -y delx-memory doctor
# Or install globally
npm install -g delx-memory
delx-memory doctor
The doctor command checks Node version, DB writability, and file permissions, then prints next steps.
HTTP (v2 stateless) Default is stdio . Optional Streamable HTTP — no session id, JSON responses, loopback only:
npx -y delx-memory --http
# GET http://127.0.0.1:3030/health
# POST http://127.0.0.1:3030/mcp (sessionless)
Env: DELX_MEMORY_HOST, DELX_MEMORY_PORT, DELX_MEMORY_TRANSPORT=http.

What makes it different (honest) Not a vector DB. Not a second brain SaaS. Local continuity for agents that already have a model.
Tools (15)
Session start
Reads
Mutations (require explicit_user_intent: true) Every mutation refuses to run unless the caller passes explicit_user_intent: true. The intent: an agent that decides on its own to update memory must show its work. The user can see the flag in the tool call and reject it if they didn't ask.
Privacy contract (read this) delx-memory is NOT a secrets manager. Use macOS Keychain / gnome-keyring / Windows Credential Manager for those.
Keys matching: oauth, token, secret, password, cookie, refresh, api_key, api-key, apikey, bearer, credential, session_id (case-insensitive).Values matching credential shapes:
JWT tokens (eyJ…)
Bearer <token> headersStripe sk_live_… / sk_test_…
Slack xoxb-… / xoxp-… / etc.
GitHub github_pat_… / ghp_… / gho_… / ghs_… / ghr_…
OpenAI / Anthropic sk-… (with realistic length)
AWS access keys AKIA…
Authorization: <scheme> <token> strings
Nested objects are walked recursively — a nested field named refresh_token (even with an empty value) is rejected.
The DB file lives at ~/.delx-memory/db.sqlite.
Directory is created with mode 0700; file with mode 0600. (Best effort on Windows / WSL / non-POSIX filesystems.)
Nothing is uploaded. No telemetry. No phone-home.
Other users of the same machine (root, your sudo-using housemate) can read the file. Use full-disk encryption (FileVault, BitLocker, LUKS) if that matters.TTL is best-effort. Expired rows are deleted lazily on next read; SQLite doesn't VACUUM automatically, so freed pages may sit on disk. For sensitive ephemera, treat the DB file like any other unencrypted dotfile.No durability promise. Back up ~/.delx-memory/db.sqlite like any other dotfile if you care about losing it.
Example session agent> memory_stats({})
→ { total_keys: 0, db_path: "/Users/me/.delx-memory/db.sqlite", … }
user> Remember that I prefer concise responses in pt-BR.
agent> memory_set({
key: "user_preferences",
value: { language: "pt-BR", verbosity: "concise" },
tags: ["profile", "preferences"],
explicit_user_intent: true
})
→ { action: "created", key: "user_preferences", … }
# … new chat, possibly different tool …
agent> memory_list({ tag: "preferences" })
→ [{ key: "user_preferences", updated_at: … }]
agent> memory_get({ key: "user_preferences" })
→ { found: true, value: { language: "pt-BR", verbosity: "concise" } }

Skill or MCP Same package, two doors. MCP registers tools on stdio/HTTP. The skill can drive the same tools through the CLI when the client has no MCP:
npx -y delx-memory call memory_connection_status --json '{}'
