Memoweft tools (8)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • memoweft_graph

    Build a memory graph payload (nodes, edges, stats) for a subject. Read-only. Archived cognitions are excluded unless includeArchived is true.

  • memoweft_ingest_tool_result

    Store the verbatim result payload returned by a tool execution as evidence (source kind: tool).

  • memoweft_ingest_user_message

    Store a single verbatim user message as spoken evidence. This only records the raw message; it does not update the profile, run consolidation, or grant any cloud-read authorization.

  • memoweft_list_cognitions

    List all stored cognitions for a subject, each with its evidence links and a read-time effective confidence. Read-only.

  • memoweft_list_events

    List all stored events for a subject, each with the ids of the evidence it covers. Read-only.

  • memoweft_list_evidence

    List all stored evidence (raw sources) for a subject. Read-only; does not expose or change authorization bits.

  • memoweft_mute_cognition

    Toggle whether a single cognition is excluded from recall (recall negative feedback).

  • memoweft_recall

    Recall stored knowledge relevant to a query. Returns cognitions with confidence and credibility status; low-credibility items are guesses, not established facts.

Runs npx -y @memoweft/mcp-server on your machine. Read the scan report first; the gateway never runs local packages.

MemoWeft

Give your AI a memory—without turning its guesses into your facts.

MemoWeft is an open-source long-term memory engine for TypeScript AI applications. It keeps what users said, what systems observed, what models inferred, and what remains conflicted as distinct records—so memory can be inspected, corrected, managed, and moved between hosts in SQLite controlled by your application.

[!IMPORTANT]

MemoWeft is a library your application imports—not a chat product, hosted memory service, persona framework, vector database, or agent framework.

Why AI memory needs a paper trail

AI can already hold a convincing conversation. What it often lacks is reliable continuity.

Across conversations, important context can disappear. New information may quietly replace old information. A model's guess may return later as if the user had stated it. Move to another model or host, and the accumulated memory may be left behind.

MemoWeft does not ask a model to declare the truth. It preserves where information came from, when it appeared, what contradicts it, and why a memory was formed—so applications and users can inspect the path from evidence to recall.

Evidence stays evidence User statements, observations, tool results, and model inferences keep distinct provenance. Conflict stays visible Corrections retain history. Unresolved contradictions are exposed instead of silently overwritten. Memory stays yours Hosts can inspect, manage, export, validate, and import versioned memory bundles.

Confidence is computed by rule rather than copied from a model's self-assessment. Transient states can age faster than durable facts and preferences. Built-in ingestion paths do not turn an assistant's own reply into user evidence simply because the assistant said it.

Try it without an API key

With Node 24 installed:

git clone https://github.com/memoweft/memoweft.git
cd memoweft
npm ci
npm run build
node examples/no-key-demo.ts

After dependencies are installed, this deterministic demo needs no API key, makes no network calls, uses an in-memory database, and writes nothing to disk.

[limited   ] conf  600/1000  The user lives in Osaka  — stated memory
[conflicted] conf  480/1000  The user lives in Tokyo  — conflict kept, not overwritten
[candidate ] conf  200/1000  The user probably works somewhere central  — guess (low confidence)
