What is Zep?

Zep provides agent memory capabilities for teams building and operating AI applications. It supports the MCP ecosystem.

Zep is a agent memory product intended for teams building or operating AI-enabled software. The vendor site describes its offering in terms that include: The vendor page could not be reliably extracted during this automated run. This profile is based on the public homepage and pricing route fetched on August 25, 2026; buyers should confirm details that affect purchasing or production architecture directly with the vendor.

For builders, the practical value is reducing the custom work needed to connect, inspect, evaluate, or operate AI applications. Typical workflows include prototyping an assistant, adding the product to an existing application, reviewing behavior with a technical or business team, and creating a repeatable production process. It is best evaluated with a representative workload: connect one real application, define success criteria, measure setup effort and output quality, then review security, data retention, access controls, and export options. Zep advertises or participates in the Model Context Protocol ecosystem in a server role. That can make it easier to expose capabilities to MCP hosts or consume MCP tools without a proprietary integration for every client.
