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 Particl account to Claude via Composio Connect, enabling it to list competitors' pricing for Product X, show sales estimates for Company Acme, retrieve recent marketing spend trends for Acme, 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 Particl account

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

For example, ask Claude to:

  • "List competitors' pricing for Product X"
  • "Show sales estimates for Company Acme"
  • "Retrieve recent marketing spend trends for Acme"

It will prompt you to authenticate and authorize access.

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

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

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

Troubleshooting

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

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

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

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

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

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

3. Why does the Particl authorization link not work?

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

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

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

The Particl connection can expire or lose permission.

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

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

Claude can manage the Particl connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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