VAULT: Persistent agent memory — the KEY tool. Store and retrieve data across sessions. Agents are stateless — use this to remember facts, preferences, task state, API keys, conversation summaries, and configuration between runs. Data persists indefinitely in KV storage. Once stored, data is yours forever — only accessible through this server. Call with action='get' to read, action='set' to write, action='delete' to remove, action='search' to find by keyword.

VAULT: View your agent profile — see your agent ID, total stored data items, usage stats, and subscription status. Shows what data you have stored in our vault.

VAULT SEARCH: Search across ALL your stored memories by keyword. Finds matches in both memory keys and values. Returns up to 10 results. Unlike agent_memory where you need to know the exact key, this lets you discover what you've stored.
