Walrus Memory Release Notes

MCP

Walrus Memory MCP v0.0.5

June 12, 2026 | GitHub

Adds the automatic memory plugin for Claude Code, Codex, Cursor, and Antigravity, along with new memwal_remember_bulk and memwal_health tools and proactive memory behavior. Also fixes the plugin bundle so it ships .mcp.json correctly.

0.0.5

Added

• Automatic memory plugin for Claude Code, Codex, Cursor, and Antigravity.
• New memwal_remember_bulk and memwal_health tools.

Fixed

• Ship the plugin's .mcp.json in the marketplace bundle. A root gitignore rule excluded it, so plugin installs loaded the lifecycle hooks but never registered the MCP server.

Changed

• Memory tools are now proactive — agents recall and save context on their own.

Fixed

• Plugin bundle now ships its .mcp.json so the MCP server registers on install.
• Automatically recover from dropped relayer connections that could hang tool calls.

---

Walrus Memory MCP v0.0.4

June 5, 2026 | GitHub

Fixes HTTPS dashboard sign-in callbacks and credential reload after login so tools work without restarting the MCP client.

0.0.4

Fixed

• Accept HTTPS dashboard sign-in callbacks to the local 127.0.0.1 MCP listener.
• Reload credentials after memwal_login so memory tools work without restarting the MCP client.

---

Walrus Memory MCP v0.0.3

June 4, 2026 | GitHub

Rebrands package metadata from MemWal to Walrus Memory throughout the MCP server.

0.0.3

Changed

---

Walrus Memory MCP v0.0.2

May 25, 2026 | GitHub

0.0.2

Added

• Added relayer compatibility metadata checks before opening the MCP bridge.

Changed

• Rebranded package metadata and documentation from MemWal to Walrus Memory.

---

Walrus Memory MCP v0.0.1

May 15, 2026 | GitHub

Initial release of the MCP server with stdio transport, browser wallet login, and inline session tools. Includes memory tools for remember, recall, analyze, and restore.

0.0.1

Initial Release

• Stdio MCP server for MemWal with browser-based wallet login.
• Inline memwal_login and memwal_logout session tools.
• Memory tools for remember, recall, analyze, and restore through the MemWal relayer.
• Environment presets for production, dev, staging, and local relayers.

TypeScript SDK

Walrus Memory TypeScript SDK v0.0.7

June 2, 2026 | GitHub

Adds an optional occurredAt parameter to analyze() for temporal anchoring of extracted facts. Relative date references are now resolved into absolute dates.

0.0.7

Patch Changes

• #218 333d327 Thanks @hungtranphamminh! - Add optional occurredAt to analyze() and analyzeAndWait() for temporal anchoring of extracted facts.

  • New AnalyzeOptions overload: analyze(text, { namespace, occurredAt }) accepts Date or RFC-3339 string. The legacy analyze(text, namespace?) signature still works unchanged.
  • When occurredAt is supplied, the server resolves in-turn relative references ("last Friday", "yesterday") into absolute dates inside the extracted fact text before embedding and encryption.
  • Wire format is RFC-3339 UTC with millisecond precision (e.g. "2023-05-25T17:50:00.000Z").
  • Invalid Date instances (constructed from malformed input) now throw a diagnostic TypeError from the SDK rather than an opaque RangeError from toISOString().
  • Field is omitted from the request body when not supplied — existing callers see byte-identical wire payloads.

---

Walrus Memory TypeScript SDK v0.0.6

May 28, 2026 | GitHub

Adds RecallParams for object-style recall calls and deprecates the positional recall overload. Also documents restore() response fields.

0.0.6

Added

• Added RecallParams for object-style recall(...) calls.

Changed

• Marked the positional recall(...) overload as deprecated in favor of recall({ query, limit, namespace }).
• Documented restore() response fields, default limit, pagination behavior, and performance expectations.

---

Walrus Memory TypeScript SDK v0.0.5

May 25, 2026 | GitHub

Adds relayer compatibility checks, RecallOptions for topK/namespace/maxDistance filtering, and prefers Sui gRPC for SEAL sessions. This release also rebrands from MemWal to Walrus Memory.

0.0.5

Added

• Added relayer compatibility metadata checks before protected requests.
• Added compatibility() and exported compatibility types/errors so callers can inspect SDK/relayer support explicitly.
• Added RecallOptions for topK, namespace override, and maxDistance.

Changed

• Prefer Sui gRPC for SEAL sessions, with JSON-RPC fallback.
• Updated docs/examples for MEMWAL_PRIVATE_KEY and hosted relayer defaults.
• Rebranded package metadata and documentation from MemWal to Walrus Memory.

Fixed

• Made 401 relayer errors more actionable.

---

Walrus Memory TypeScript SDK v0.0.4

May 15, 2026 | GitHub

Adds getRememberStatus for polling async job state and SealServerConfig for manual SEAL configuration. Manual mode validates API key pairs.

0.0.4

Added

• Added getRememberStatus(jobId) so clients can poll and display the full async remember state machine.
• Added SealServerConfig and sealServerConfigs for manual-mode SEAL committee aggregator configuration.

Changed

• Manual mode now normalizes full SEAL server configs, validates optional API key pairs, and caps the default threshold to configured server weight.
• Manual mode keeps testnet defaults on the legacy independent key servers for compatibility with hosted testnet relayer data.

---

Walrus Memory TypeScript SDK v0.0.3

May 8, 2026 | GitHub

Updates remember() for the async relayer flow and introduces rememberAsync, waitForRememberJob, rememberAndWait, and bulk remember helpers. Also adds async analysis with analyzeAndWait.

0.0.3

Changed

• Updated remember() for the relayer's async /api/remember flow. It now returns the accepted job payload immediately.
• Added rememberAsync(), waitForRememberJob(), and rememberAndWait() for callers that need the final blob_id.
• Added bulk remember helpers: rememberBulk(), rememberBulkAsync(), waitForRememberJobs(), and rememberBulkAndWait().
• Updated analyze() for async fact storage and added analyzeAndWait().

Compatibility

• recall() and restore() remain wire-compatible with the existing relayer responses.
• The SDK continues to use x-seal-session for relayer-mode decrypt credentials.

---

Walrus Memory TypeScript SDK v0.0.2

April 30, 2026 | GitHub

Adds per-request nonce signing to block replay attacks and replaces delegate key transport with ephemeral SEAL sessions. SDK versions that do not include a nonce are rejected with HTTP 426.

0.0.2

Security

• Added per-request x-nonce signing to block replay within the timestamp window.
• Added x-account-id to the canonical signed message so account hints cannot be rebound in transit.
• Replaced relayer-mode x-delegate-key transport with ephemeral x-seal-session; manual-mode requests no longer send delegate private key material.
• SDK versions that do not send x-nonce are no longer supported by the server and receive 426 Upgrade Required.

OpenClaw

Walrus Memory SDK v0.0.5

June 15, 2026 | GitHub

Fixes a workspace dependency that broke npm installs outside the monorepo and switches the release workflow to pnpm publish.

0.0.5

Patch Changes

• Fix unresolvable workspace:* dependency in the published package. The release workflow used npm publish, which ships package.json verbatim and cannot rewrite the workspace: protocol, so the published artifact carried "@mysten-incubation/memwal": "workspace:*" and failed to install outside the monorepo (Unsupported URL Type 'workspace:'). Switched the release workflows to pnpm publish, which rewrites workspace:* to the concrete dependency version at pack time.

---

Walrus Memory SDK v0.0.4

June 2, 2026 | GitHub

Adds temporal anchoring through occurredAt to the memory_store tool. The auto-capture hook now passes the current timestamp, and the SDK is bumped for the new AnalyzeOptions.

0.0.4

Patch Changes

• #218 333d327 Thanks @hungtranphamminh! - Wire temporal anchoring through the agent-side memory tools.

  Added

  • memory_store tool now accepts an optional occurredAt argument (RFC-3339 / ISO-8601 string) so agents can anchor recounted past events to the date they actually occurred. Description tells the LLM to omit it when unknown rather than guess.

  Changed

  • Auto-capture hook (agent_end) now passes new Date() as occurredAt to analyze(). Every captured conversation now gets temporal anchoring automatically — the server extractor resolves in-turn relative references ("yesterday", "last Friday") into absolute dates inside the stored fact text. Facts captured by this version now carry resolved dates.
  • SDK dependency bumped from published ^0.0.2 to workspace:* to consume the new AnalyzeOptions signature.

• Updated dependencies [333d327]:

  • @mysten-incubation/memwal@0.0.7

---

Walrus Memory SDK v0.0.2

April 30, 2026 | GitHub
