Titen

Agent memory that runs with no API key, no LLM, and no embedding provider.
Every memory keeps its source, who may read it, and the evidence that contradicts it.

Built with C.A.D.I.S Agent.

Try it in 30 seconds

No account, no key, no configuration — but the CLI runs on Bun 1.2 or newer, and refuses to start without it:

curl -fsSL https://bun.sh/install | bash   # skip if you already have Bun
npx titen-memory mcp

With no environment set, that opens or creates ~/.titen/memory.db, writes a real organization, workspace, project and owner into it, and serves MCP over stdio in-process — no HTTP hop, no key to paste, and no outbound network call. Retrieval is FTS5, so nothing needs an embedding provider or a model.

curl -fsSL https://titen.dev/install.sh | bash does the same in one step: it adds Bun when it is missing, then installs the titen command.

Point an agent at it:

claude mcp add --transport stdio --scope user titen -- npx -y titen-memory mcp

Already using @modelcontextprotocol/server-memory? Titen serves the same nine tool names with the same schemas, and answers memory://knowledge-graph too, so a client does not notice the swap. On the first local-mode start it imports your existing graph. Pass the old store's path, because that server writes beside its own install rather than in the directory you launch it from:

claude mcp add --transport stdio --scope user titen \
  --env MEMORY_FILE_PATH=/path/to/memory.jsonl -- npx -y titen-memory mcp

Without it Titen still checks the working directory, its node_modules, and npm's npx cache — and says on stderr when it found nothing, rather than starting empty in silence. Point titen at a served instance later by setting TITEN_MCP_URL and TITEN_API_KEY — full setup below.

Audit what any agent memory store has accumulated, including one Titen does not own:

npx titen-memory audit ./memory.json

What is different about it

• No provider, no key, no account. FTS5 lexical retrieval is the default operating point, not a fallback. Embeddings and model enrichment are opt-in projections that degrade cleanly when they are absent.
• No runtime dependencies. package.json declares none. What it needs is Bun and one SQLite file; everything else is the standard library and Web APIs.
• **Drop-in for `@modelcontextprotocol/server-me
