Glen MCP is an organizational memory service that gives teams access to shared knowledge and context. It helps users find trusted workspace information without digging through scattered sources.

22 Tools

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 Glen account to Claude via Composio Connect, enabling it to search Glen for recent project decisions, find onboarding context for the Acme account, summarize Glen notes about product launch risks, 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.

3. Connect your Glen account

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

For example, ask Claude to:

  • "Search Glen for recent project decisions"
  • "Find onboarding context for the Acme account"
  • "Summarize Glen notes about product launch risks"

It will prompt you to authenticate and authorize access.

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

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

The Glen MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Glen account. It provides structured and secure access to your organization's shared memory, artifacts, reusable skills, and Glen settings, so your agent can search team knowledge, save and retrieve documents, create and use reusable skills, trace code to past conversations, and manage sharing and recording preferences on your behalf.

  • Search organizational memory: Have your agent search Glen for past decisions, context, and team knowledge, then exclude outdated evidence or restore it later.
  • Manage shared artifacts: Let the agent find, retrieve, create, share, or delete Markdown and HTML documents in your organization's artifact library.
  • Create and use team skills: Direct your agent to find reusable skills, fetch their instructions, save new skills, share them with teammates, or delete skills you authored.
  • Trace code and preserve conversations: Instruct your agent to connect specific code lines to the conversations that produced them or import a past coding-agent conversation into shared memory.
  • Manage Glen workspace settings: Have your agent check organizations, invite teammates, change recording and skill suggestion settings, and send feedback or bug reports to Glen.

Troubleshooting

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

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

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

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

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

  • 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 Glen.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Glen authorization link not work?

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

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

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

The Glen connection can expire or lose permission.

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

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

Claude can manage the Glen connection for you.

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

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

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

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Glen 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 Glen.

FAQ

Frequently asked questions

With a standalone Glen MCP server, the agents and LLMs can only access a fixed set of Glen tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Glen 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 Glen tools.

Yes, absolutely. You can configure which Glen 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 Glen data and credentials are handled as safely as possible.
