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 MagicSlides 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 MagicSlides MCP server, and what's possible with it?

The MagicSlides MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your MagicSlides account. It provides structured and secure access to presentation generation, templates, and supported AI models, so your agent can create editable presentations, generate HTML slide decks, find suitable templates, and review available AI models on your behalf.

  • Editable presentation creation: Have your agent turn a topic or source content into an editable MagicSlides presentation and provide a link to continue editing it.
  • Template-based slide generation: Direct your agent to create a presentation with a selected ProSlides template and return HTML slides plus preview, PowerPoint, and PDF links.
  • Presentation template discovery: Let the agent list available presentation templates and identify options that support ProSlides HTML output.
  • AI model selection: Instruct your agent to review supported HTML Studio models and compare their quality and speed guidance before creating slides.

Conclusion

You've successfully integrated MagicSlides with Codex using Composio's MCP server. Now you can interact with MagicSlides 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 MagicSlides 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 MagicSlides 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 MagicSlides MCP server, the agents and LLMs can only access a fixed set of MagicSlides tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from MagicSlides 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 MagicSlides tools.

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