MemoryOracle

Persistent long-term memory for AI agents. Agents never forget.

10 tools. SQLite FTS5 full-text search. Per-namespace isolation. GDPR-compliant forget. Cross-references with FeedOracle Trust Layer.

The problem

Every MCP tool call is stateless. When Claude Desktop restarts, when Cursor closes, when the session ends — the agent forgets everything. No user preferences, no project history, no learned rules, no portfolio tracking.

MemoryOracle gives agents a persistent, searchable memory that survives restarts, works across clients, and gets more valuable over time.

Example: Compliance agent workflow

Session 1 — Agent does MiCA compliance checks:

{"name": "store_memory", "arguments": {
  "content": "USDT blocked for EU — MiCA NOT AUTHORIZED. Preflight: STOP.",
  "category": "decision", "importance": 10,
  "tags": ["usdt", "mica", "blocked"],
  "namespace": "compliance-bot"
}}

Session 2 — Next day, agent remembers:

{"name": "query_memory", "arguments": {
  "query": "USDT EU compliance status",
  "namespace": "compliance-bot"
}}

→ Instantly recalls the decision from yesterday. No re-checking needed.

End of session — Auto-capture:

{"name": "summarize_session", "arguments": {
  "summary": "Reviewed stablecoin portfolio. USDT blocked. RLUSD pending.",
  "key_facts": ["USDC authorized", "EURC authorized", "USDT blocked"],
  "decisions": ["Block USDT for EU"],
  "action_items": ["Check RLUSD in April 2026"],
  "namespace": "compliance-bot"
}}
