Why use Composio?

Apart from a managed and hosted MCP server, you will get:

  • CodeAct: A dedicated workbench that allows GPT to write its code to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling.
  • Large tool responses: Handle them to minimise context rot.
  • Dynamic just-in-time access to 20,000 tools across 1000+ other Apps for cross-app workflows. It loads the tools you need, so GPTs aren't overwhelmed by tools you don't need.

How to install Copyleaks MCP in Codex

Run the setup command

Run this command in your terminal to add the Composio MCP server to Codex.

Terminal

It will initiate the authentication in a browser window, authorize Codex to access your Composio account.

Composio authentication page

(Optional) Authenticate with OAuth

To authenticate manually, run the login command to open a browser window and authorize Codex to access your Composio account.

bash
codex mcp login composio

Verify the connection

Run codex mcp list to confirm Composio appears as a registered MCP server.

bash
codex mcp list

Codex App

Codex App follows the same approach as VS Code.

  1. Click ⚙️ on the bottom left → MCP Servers → + Add servers → Streamable HTTP:
  2. Fill the header and Key fields with { "x-consumer-api-key" = "ck_*******" }.
  3. The Key is the Composio API key, that you can find on dashboard.composio.dev
  4. Click on Authenticate and authorize Codex to your Composio account and you're all set.
Codex App MCP setup
  1. Restart and verify if it's there in .codex/config.toml
bash
[mcp_servers.composio]
url = "https://connect.composio.dev/mcp"
http_headers = { "x-consumer-api-key" = "ck_*******" }

What is the Copyleaks MCP server, and what's possible with it?

The Copyleaks MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Copyleaks account. It provides structured and secure access to Copyleaks content analysis and account information, so your agent can assess writing quality, detect AI-written text, moderate harmful content, check credit balances, and review supported analysis options on your behalf.

  • Writing quality analysis: Have your agent review text for grammar, mechanics, structure, word choice, and readability, then use the feedback to guide revisions.
  • AI text detection: Let the agent classify submitted text as human-written or AI-written.
  • Harmful content moderation: Direct your agent to analyze text for harmful-content labels before it is published or shared.
  • Credit balance checks: Instruct your agent to check both your general scan credits and your separate AI Text Detector balance.
  • Supported capability lookup: Have your agent review supported OCR languages, file types, cross-language options, and writing correction definitions before starting an analysis.

Conclusion

You've successfully integrated Copyleaks with Codex using Composio's MCP server. Now you can interact with Copyleaks directly from your terminal, VS Code, or the Codex App using natural language commands.

Key benefits of this setup:

  • Seamless integration across CLI, VS Code, and standalone app
  • Natural language commands for Copyleaks operations
  • Managed authentication through Composio
  • Access to 20,000+ tools across 1000+ apps for cross-app workflows
  • CodeAct workbench for complex tool chaining

Next steps:

  • Try asking Codex to perform various Copyleaks operations
  • Explore cross-app workflows by connecting more toolkits
  • Build automation scripts that leverage Codex's AI capabilities

FAQ

Frequently asked questions

With a standalone Copyleaks MCP server, the agents and LLMs can only access a fixed set of Copyleaks tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Copyleaks and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Codex 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 Copyleaks tools.

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