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 Textcortex account to Claude via Composio Connect, enabling it to summarize this research article for me, generate a follow-up email to a client, paraphrase this paragraph in simpler terms, 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 Textcortex account

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

For example, ask Claude to:

  • "Summarize this research article for me"
  • "Generate a follow-up email to a client"
  • "Paraphrase this paragraph in simpler terms"

It will prompt you to authenticate and authorize access.

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

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

The Textcortex MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Textcortex account. It provides structured and secure access to advanced text generation and summarization capabilities, so your agent can perform actions like drafting emails, paraphrasing content, summarizing long texts, and personalizing communication on your behalf.

  • Automated email generation: Instantly draft personalized email subjects and bodies based on your prompts or specific instructions.
  • Concise text summarization: Have your agent quickly distill long articles, documents, or messages into clear, actionable summaries.
  • Content rephrasing and paraphrasing: Get alternative phrasings or rewording suggestions for existing text, tailored for clarity or tone.
  • Personalized content creation: Ask your agent to compose unique written content for outreach, marketing, or daily communication needs.

Troubleshooting

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

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

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

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

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

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

3. Why does the Textcortex authorization link not work?

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

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

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

The Textcortex connection can expire or lose permission.

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

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

Claude can manage the Textcortex connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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