Context Vault MCP server

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

• recall

  Recall a prompt-ready, time- and permission-correct context string for `user` — only facts this user may see, valid at `as_of` (ISO; default now), contradictions filtered. `as_of` reconstructs the past (time-travel).

• remember

  Remember fact(s) from natural-language text for `user`. Extracts claims and asserts them — every claim is conflict-checked (a contradiction is flagged, never silently stored). review=True queues the extracted claims for human approval instead of auto-asserting. Needs ANTHROPIC_API_KEY; without it, use vault_assert(subject, predicate, object).

• vault_assert

  Advanced: assert a STRUCTURED claim (subject, predicate, object) — works with no API key (heuristic judge). Runs conflict detection and returns the relation/action taken.

• vault_audit_replay

  Advanced: replay exactly what `principal_id` was served at/before `as_of` (ISO time).

• vault_register_principal

  Advanced: attach visibility labels to a principal for GOVERNED SHARING across a team. Not required for remember/recall — those auto-create a private, per-user principal. Preserves an existing principal's workspaces (this tool takes none) so a relabel never silently resets tenant scope — surface parity with the admin /principals + CLI register paths.

• vault_resolve

  Advanced: resolve the current, visible truth for a specific principal at a point in time (returns the raw facts + claim ids, not a packed string).

• wake_up

  Start a session with a token-budgeted, governed context pack — everything this server's principal may see about `query`, valid at `as_of` (ISO; default now), with the token cost.
