MemoStem MCP server

• check_memostem_connectionFree

  Verify the authenticated MemoStem connection and report only the currently granted knowledge permissions. This test does not read or write knowledge.

• claim_guest_knowledge_workspacewrite actionFree

  Transfer the temporary guest shelf identified by workspace_token to the authenticated MemoStem owner as private pending drafts. Call only after the person explicitly agrees to connect or after the guest shelf reports account_required. This tool never approves or publishes cards.

• create_card_draftswrite actionFree

  Create pending, user-owned general-knowledge card drafts only after clear affirmative consent to specifically named, independently teachable knowledge in the current conversation. Every card must declare knowledge_scope as general_knowledge. Personal or company decisions, product principles or policies, pricing rationale, preferences, plans, tasks, reminders, meeting outcomes, project status, and autobiographical facts are ineligible. An assistant suggestion alone is not consent. This tool never accepts raw transcripts or historical-conversation data, and it cannot approve, publish, or modify public knowledge cards.

• create_knowledge_bundle_draftswrite actionFree

  Create pending, user-owned concept, general procedure, comparison, mechanism, structure, claim/evidence, knowledge question, historical event, or language-expression drafts only after clear affirmative consent to specifically named, independently teachable general knowledge in the current conversation. Every bundle must declare knowledge_scope as general_knowledge; decisions and organization-specific material are not accepted. An assistant suggestion alone is not consent. It cannot approve drafts, retain transcripts, or modify public knowledge.

• preview_knowledge_bundleFree

  Return a transient preview of exactly one user-selected, independently teachable general-knowledge bundle without an account and without saving it. Call only at the person's direct request or after clear acceptance of a specific preview proposal. Use save_guest_knowledge_bundles only after the person explicitly asks to keep it; connected clients use create_knowledge_bundle_drafts.

• save_guest_knowledge_bundlesFree

  Store one to 10 specifically selected, independently teachable general-knowledge bundles from the current conversation in a private temporary MemoStem guest shelf. Call only after a direct request or clear acceptance of a specific proposal. Reuse workspace_token to continue the same shelf, but never reveal that credential to the person. The shelf is read-only in MemoStem, expires after 90 days, and requires account connection at 10 cards.

• validate_knowledge_bundleFree

  Validate exactly one user-selected, independently teachable general-knowledge bundle without an account and without saving it. Call only at the person's direct request or after clear acceptance of a specific preview proposal. The strict input rejects transcripts, conversation histories, personal or organization-specific memory, and unsupported knowledge types.
