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 Textrazor account to Claude via Composio Connect, enabling it to extract named entities from this news article, summarize key phrases in customer reviews, classify support tickets by topic automatically, 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.

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

The Textrazor MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Textrazor account. It provides structured and secure access to advanced natural language processing features, so your agent can extract entities, classify content, analyze grammar, and understand relationships within text—all automatically and at scale.

  • Entity and relationship extraction: Enable your agent to identify and classify people, places, organizations, and relationships from any text, powering intelligent content analysis and knowledge graph building.
  • Text classification and categorization: Automatically categorize documents, articles, or snippets using built-in or custom classifiers, making it easy to sort and organize large volumes of text data.
  • Grammatical and dependency analysis: Let your agent parse sentence structure, analyze grammatical relationships, and build dependency trees to support advanced linguistic understanding and text analytics.
  • Custom dictionary and classifier management: Allow the agent to create and update custom entity dictionaries and classifiers, tailoring analysis to specialized domains or business needs.
  • Phrase extraction and sentiment detection: Extract key phrases, multi-word expressions, and even detect logical entailments or word senses, enabling deeper insights from any written content.

Troubleshooting

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

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

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

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

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

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

3. Why does the Textrazor authorization link not work?

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

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

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

The Textrazor connection can expire or lose permission.

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

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

Claude can manage the Textrazor connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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