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 Rosette text analytics account to Claude via Composio Connect, enabling it to detect language of this customer review, compare these two addresses for similarity, check if these organization names match, 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.

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 Rosette text analytics account

Back in Claude, ask it to connect to Rosette text analytics or give it any Rosette text analytics-related task.

For example, ask Claude to:

  • "Detect language of this customer review"
  • "Compare these two addresses for similarity"
  • "Check if these organization names match"

It will prompt you to authenticate and authorize access.

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

What is the Rosette text analytics Claude Connector, and what's possible with it?

The Rosette text analytics MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Rosette text analytics account. It provides structured and secure access to Rosette's powerful text analysis features, so your agent can identify languages, compare addresses, and evaluate name similarities on your behalf.

  • Automatic language identification: Instantly detect the natural language of any given text, including confidence scores and genre-specific analysis.
  • Address similarity scoring: Compare two addresses—single strings or structured objects—and receive a similarity score to help with deduplication or data matching.
  • Name similarity comparison: Evaluate how similar two names (person, organization, or location) are, returning a score for identity resolution or record linkage.
  • Multilingual and cross-script support: Analyze and process text across hundreds of language, encoding, and script combinations without manual intervention.

Troubleshooting

1. Why does Claude not use the Composio connector for Rosette text analytics?

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

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

2. Why does Claude show an MCP server error before Rosette text analytics connects?

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

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

3. Why does the Rosette text analytics authorization link not work?

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

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

4. Why do Rosette text analytics actions fail after they worked before?

The Rosette text analytics connection can expire or lose permission.

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

5. How do I switch to a different Rosette text analytics account?

Claude can manage the Rosette text analytics connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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