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

The Daily MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Daily account. It provides structured and secure access to your Daily rooms, meeting tokens, participant presence, meeting analytics, and domain settings, so your agent can create and manage rooms, issue and validate meeting tokens, check who is present, review meeting activity, and inspect account capabilities on your behalf.

  • Room creation and management: Have your agent create one room or many rooms at once, list existing rooms, adjust room privacy and meeting defaults, or delete rooms you no longer need.
  • Meeting token controls: Let the agent issue time-limited meeting tokens for specific rooms and participants, then validate their room and participant settings before a call.
  • Live participant checks: Direct your agent to check who is currently present in a room and narrow the results by user or display name.
  • Meeting activity review: Instruct your agent to review meeting sessions by room, time range, or current session state.
  • Domain and room inspection: Have your agent retrieve a room's current privacy and configuration or inspect your Daily domain identity and account capability signals.

Conclusion

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

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