Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your Zep account to Claude via Composio Connect, enabling it to store a memory about today's meeting, retrieve all memories tagged urgent, summarize knowledge about client preferences, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

2. Add the Composio MCP server

Click Add custom connector and paste in the Composio MCP server URL:

bash
https://connect.composio.dev/mcp
Add custom connector dialog with Composio MCP server URL

3. Authorize in your browser

Click Connect. You'll be redirected to a browser window where you can authorize Composio to continue.

4. Connect your Zep account

Back in Claude, ask it to connect to Zep or give it any Zep-related task.

For example, ask Claude to:

  • "Store a memory about today's meeting"
  • "Retrieve all memories tagged urgent"
  • "Summarize knowledge about client preferences"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your Zep account is ready to use.

What is the Zep Claude Connector, and what's possible with it?

The Zep MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Zep account. It provides structured and secure access so your agent can perform Zep operations on your behalf.

Troubleshooting

1. Why does Claude not use the Composio connector for Zep?

The connector can show as connected, but Claude must use it in each Zep conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to Zep again.

2. Why does Claude show an MCP server error before Zep connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Zep.

  • Check that the connector URL is https://connect.composio.dev/mcp.
  • Connectors run from Anthropic's cloud, so your device network is usually not the problem.
  • Add the connector again from Customize > Connectors, then ask Claude to connect Zep.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Zep authorization link not work?

The Composio connector is one server. Your Zep account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the Zep connection.
  • Composio creates a fresh Zep authorization link.
  • Open that link in your browser and finish the Zep sign-in.

4. Why do Zep actions fail after they worked before?

The Zep connection can expire or lose permission.

  • Ask Claude to inspect the Zep connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the Zep account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in Zep.
  • If the action still fails with a permission error, check that the connected account has that permission in Zep itself.

5. How do I switch to a different Zep account?

Claude can manage the Zep connection for you.

  • Ask Claude to disconnect or delete the current Zep account.
  • Ask Claude to connect Zep again.
  • Open the new Composio authorization link for Zep.
  • Sign in with the other Zep account in the browser.
  • After the account connects, ask Claude to retry the Zep task.

6. Why is my Zep connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Zep connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Zep tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
  • On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Zep.

FAQ

Frequently asked questions

With a standalone Zep MCP server, the agents and LLMs can only access a fixed set of Zep tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Zep and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Zep tools.

Yes, absolutely. You can configure which Zep scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Zep data and credentials are handled as safely as possible.
