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 Chartly account to Claude via Composio Connect, enabling it to render monthly sales chart as PNG image, create shareable chart URL for dashboard, convert Chart.js config to downloadable SVG, 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 Chartly account

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

For example, ask Claude to:

  • "Render monthly sales chart as PNG image"
  • "Create shareable chart URL for dashboard"
  • "Convert Chart.js config to downloadable SVG"

It will prompt you to authenticate and authorize access.

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

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

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

Troubleshooting

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

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

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

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

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

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

3. Why does the Chartly authorization link not work?

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

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

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

The Chartly connection can expire or lose permission.

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

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

Claude can manage the Chartly connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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