Usage

Three tools available in Claude Code:

zep_store_memory

Store information in a Zep session.

zep_search_memory

Search for information in a Zep session.

zep_get_memory

Get recent memories from a session with pagination and filtering support.

Parameters:

• session_id (required): Thread/Session ID to retrieve

• lastn (optional): Number of most recent messages to return (e.g., 50, 100, 200)

• limit (optional): Limit the number of results returned (alternative to lastn)

• cursor (optional): Cursor for pagination (used with limit)

• role_filter (optional): Filter by message role: "user", "assistant", or "system"

Examples:

# Get last 50 messages from a large session
zep_get_memory(session_id="esme", lastn=50)

# Get only assistant messages
zep_get_memory(session_id="esme", lastn=100, role_filter="assistant")

# Use cursor-based pagination
zep_get_memory(session_id="esme", limit=50, cursor=0)

Thread/Session Naming Convention

• Global knowledge: global

• Project-specific: project-{name}

• User-specific: user-{username}

Note: This server uses Zep Cloud v3 API which uses "threads" instead of "sessions". The tools still accept session_id for backwards compatibility.

Example

Store in session 'global':
