Zep MCP Server

Simple MCP server that wraps Zep Cloud API (v3) for use with Claude Code.

Enables Claude Code to store and retrieve memories using Zep's thread-based memory system.

Installation

git clone https://github.com/yourusername/zep-mcp-server.git
cd zep-mcp-server
npm install
npm run build

Configuration

Add to your ~/.claude.json:

{
  "mcpServers": {
    "zep": {
      "command": "node",
      "args": ["/absolute/path/to/zep-mcp-server/dist/index.js"],
      "env": {
        "ZEP_API_KEY": "z_your_zep_api_key"
      }
    }
  }
}

Get your Zep API key from https://www.getzep.com

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':
