Machine-readable install and operating instructions for AI agents. Call first when onboarding. Supports privacy_mode documentation for read tools.

Local SQLite path readiness and size without reading entry values. Safe first call every session.

Static inventory of memory domains, privacy modes and recommended first calls. No live value reads.

Self-description of this MCP including privacy modes and mutation gating.

Exact key lookup. Returns the stored value plus timestamps, ttl, tags, metadata. Returns null if missing or expired. Optional privacy_mode=summary omits full values.

List keys with optional prefix, tag, or since (updated_at) filter. Returns keys + timestamps + tags only — call memory_get for values. Scoped by DELX_MEMORY_NAMESPACE when set.

Full-text search across keys, values AND tags. Uses an FTS5 index with bm25 relevance ranking (key-weighted), word-stemming, diacritic folding and prefix matching — so multi-word, partial and accent-insensitive queries all hit, ranked by relevance. Falls back to a LIKE substring scan if the SQLite build lacks FTS5. Returns top N matches with a snippet. Case-insensitive. privacy_mode=summary omits snippets.

High-level stats about the local memory store. Safe to call first on every session to gauge whether the store is empty, small, or large.

Create or update a key in memory. Rejects credential-shaped keys or values. Requires explicit_user_intent: true. Returns whether the row was created or updated.

Delete a single key from memory. Idempotent: returns existed=false if the key was not present. Requires explicit_user_intent: true.

Delete every entry carrying the given tag. Returns deleted_count. Requires explicit_user_intent: true.

Dump the memory store as JSON, JSONL, or Markdown. Optional since/until window on updated_at. Use for backup/inspection. Requires explicit_user_intent: true.

Batch exact-key lookup (max 50). Missing keys omitted. Respects DELX_MEMORY_NAMESPACE.

Upsert up to 50 entries in one SQLite transaction. One explicit_user_intent covers the batch. Rejects secret-shaped keys/values. Namespace-aware.

Returns store stats + the most recently updated keys (optional values). Designed for session start: one call instead of stats+list+get fan-out. Namespace-aware.
