Save a fact to the user's Walrus Memory personal memory. Call ONLY when the user explicitly asks to remember/save something. Pass the full, detailed text — never summarize.

Search the user's Walrus Memory for facts relevant to a query. Returns matching memories ranked by relevance.

Extract memorable facts from a passage of text (preferences, habits, biographical info, constraints) and save each as a separate Walrus Memory memory.

Re-index a namespace from Walrus blobs back into the relayer's search index. Returns counts and truncated status; call again with a higher limit when truncated=true.

Sign this MCP client into your Walrus Memory account by opening a browser. Run once when the agent reports Walrus Memory is not signed in. Opens the dashboard in the default browser, waits for wallet approval, then writes credentials to ~/.memwal/credentials.json. Other memwal_* tools become usable on the next call after a successful login.
