ctxstore — memory that follows you across models

Publisher-provided description

Persistent memory for AI agents: keyed facts, a wake bundle each session, one memory in every model.

Summary by lookupd

Stores and retrieves persistent keyed facts and session summaries for agents, and shares namespaces with other accounts via email invites.

• accept_invite Accept a namespace invitation addressed to THIS authenticated account's verified email (two-step email OTP). Steps: 1) step='request' — emails a 6-digit code t
• bind_agent Bind a sticky agent identity to this MCP session. Once bound, wake_status and load_context default to this agent_id when called without an explicit agent_id= ar
• decline_invite Decline a pending (status=invited) namespace invitation as the grantee. Server verifies you are the invitee (email/tenant match). Grantors must use revoke_grant
• delete_fact Soft-delete a stored fact by its UUID (Smart Forget). The fact is marked deleted but preserved in the database for audit and undo. Excluded from all normal sear
• get_fact Retrieve a fact by its exact key — deterministic, never misses. Use get_fact for self-notes: get_fact(key='agent:<name>:self-note:opening') or get_fact(key='age
• get_fact_history Return the full version history for a keyed fact — current version plus all deprecated predecessors. Use to see how a fact evolved over time or to undo an accid
• get_session_seed Return the pre-computed session seed for this tenant — a compact first-person bio (~500 tokens) describing who you are and what you care about right now. Genera
• get_stats Get your memory usage statistics — total facts stored, plan limits, collection sizes, and daily query counts. Call this to check how much storage you have used
• ghost_mode Enable or disable ghost mode for this session. While on=True, store_fact and store_session_summary silently succeed but do NOT write to DB. search_facts, load_c
• index_recent Return the most recent fact operations across all agents in this tenant, newest first. Use this on session start to see what other agents wrote since you were l
• index_search Filtered search over the tenant activity index. Find what a specific agent wrote, what happened in a namespace, or recent creates/updates/deletes. Useful for co
• index_stats Usage statistics from the tenant activity index: total operations, breakdown by agent, by namespace, and by day. Useful for understanding which agents are most
• introduce_yourself Optional: introduce yourself to the platform. Stores your model info and a brief note in the shared agent registry. Stores a fact with: category: identity
• invite Invite one person, by email, to read and write one namespace prefix of THIS account (for example project:barn). Creates a pending grant and emails them; nothing
• leave_grant Leave an active namespace grant as the grantee (stop using shared namespace). Server verifies grantee authorization. Grantors who want to cut off a collaborator
• list_facts_by_key_prefix Deterministic prefix scan over fact keys, optionally bounded by timestamp. The inbox primitive — use this for R1 comms scans, dispatch discovery, trio listings,
• list_invites List this account's namespace collaboration grants: incoming invitations and outgoing shares. Each row has direction (incoming|outgoing), status (invited|active
• list_workspaces The places this account's memory is organised into: its own projects (anything written under project:<slug>:*, newest activity first), the workspaces other peop
• load_context Load your bootstrap context deterministically — pulls L0 (identity) + L1 (architecture) + latest L2 (state) + latest L3 (session summary). Call this at the STA
• mark_salient Salience peptide — temporarily boost a fact's retrieval ranking because it matters RIGHT NOW: an approaching deadline, a live incident, the topic under active w
• move_fact Move a fact to a different namespace or layer without changing its content. Updates metadata in place — preserves fact_id, text, embedding, timestamp, and depre

• resume_session Call to load session continuity. Last session: no prior session.
• revoke_grant Revoke a pending invitation or active grant as the GRANTOR (owner of the shared namespace). Idempotent. Grantees use decline_invite / leave_grant.
• search_context Search across ingested conversations and session history for broader context. Use this for finding discussions, decisions made in conversation, or context that
• search_facts Search your persistent memory for stored facts. For session bootstrap, prefer load_context() or wake_status() — they pull your identity, conventions, and lates
• setup_account Set up or restore your persistent memory connection. Use mode='link_or_create' when the user gives an email — works for both new and returning users. The serve
