Exist is a personal analytics app that combines data from multiple services to help you understand and improve your life. It reveals trends and insights about your habits, mood, and productivity to drive self-improvement.

12 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 Exist account to Claude via Composio Connect, enabling it to show your top positive habits last month, list strongest correlations in your data, summarize your tracked mood this week, 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.

Add to Claude

Add manually

In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top.

Add custom connector dialog with Composio MCP server URL

2. Authorize in your browser

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

3. Connect your Exist account

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

For example, ask Claude to:

  • "Show your top positive habits last month"
  • "List strongest correlations in your data"
  • "Summarize your tracked mood this week"

It will prompt you to authenticate and authorize access.

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

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

The Exist MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Exist account. It provides structured and secure access to your personal analytics data, so your agent can perform actions like analyzing correlations, retrieving user attributes, exploring supported metrics, and inspecting your profile on your behalf.

  • Personal profile access and insights: Instantly retrieve and review your Exist user profile, including preferences and account settings, to keep your agent aware of your context.
  • Attribute exploration and discovery: Browse and list all available attribute templates or user attributes, making it easy to understand what metrics you can track, analyze, or visualize.
  • Correlation analysis: Ask your agent to fetch and explore recent correlations between tracked attributes—like how weather or sleep might relate to your mood or productivity.
  • Custom analytics setup: Let your agent help you discover and understand supported attribute templates before you start tracking or updating new data points.

Troubleshooting

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

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

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

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

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

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

3. Why does the Exist authorization link not work?

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

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

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

The Exist connection can expire or lose permission.

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

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

Claude can manage the Exist connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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