Store conversation context in agent memory with automatic importance scoring and embedding. Supports multi-session tracking and memory decay.

Search agent memory semantically using natural language queries. Supports cross-session search and filtering by tags, user, or time range.

Get full conversation context window for a session with smart pruning. Automatically manages token limits, applies memory decay, and prioritizes important/recent memories.

Generate vector embeddings for text using BAAI BGE models. Useful for manual vector operations or custom similarity calculations.

Search memory by semantic similarity without needing a text query. Directly search using vector embeddings or similar memories.

Clear all memories for a session. Use with caution - this permanently deletes conversation history.

Retrieve and LLM-synthesize relevant memories into a coherent context string. Searches memory for the query, retrieves top results, then uses Claude Haiku to synthesize a narrative, bullet list, or structured summary. Returns a ready-to-use context string for grounding AI responses.

Configure ambient memory injection. When enabled, ZeroDB automatically retrieves relevant memories before each tool call and prepends them as context — agents get memory without calling recall() explicitly.

Get the current auto-context configuration for an agent.

Send a Slack message using your stored Slack OAuth connection. No API key required — uses the token from your connected Slack account in ZeroDB.

Reply to a Gmail thread using your stored Google OAuth connection. Sends from your connected Gmail account.

Create a Google Calendar event using your stored Google OAuth connection.

Create a GitHub issue using your stored GitHub OAuth connection.

Create a Notion page using your stored Notion OAuth connection.

Create a persistent plan, PRD, or task artifact in ZeroDB. Returns an artifact ID you can pass to zerodb_plan_get/update/history in future sessions.

Retrieve a plan artifact by ID. Use this at session start to restore a plan from a previous session.

Update a plan artifact. Content changes are diffed and stored in version history automatically.

Get version history for a plan artifact. Returns list of diffs showing how the plan evolved.
