How to integrate Sympla MCP with Codex
Connect Codex to Sympla MCP. Show all upcoming published events, list past events sorted by date, and more using natural language, with authentication handled for you.
Api Key
Sympla is a platform for managing in-person and online events, ticket sales, and registrations. It streamlines event setup, attendee tracking, and digital content delivery.

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 1700+ 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 Sympla MCP in Codex
Run the setup command
Run this command in your terminal to add the Composio MCP server to Codex.
It will initiate the authentication in a browser window, authorize Codex to access your Composio account.
(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 composioVerify the connection
Run codex mcp list to confirm Composio appears as a registered MCP server.
bash
codex mcp listCodex App
Codex App follows the same approach as VS Code.
- Click ⚙️ on the bottom left → MCP Servers → + Add servers → Streamable HTTP:
- Fill the header and Key fields with
{ "x-consumer-api-key" = "ck_*******" }. - The Key is the Composio API key, that you can find on dashboard.composio.dev
- Click on Authenticate and authorize Codex to your Composio account and you're all set.
- 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_*******" }Try it
Ask Codex for a Sympla task. The first time, Composio asks you to connect your Sympla account.
For example, ask it to:
- "Show all upcoming published events"
- "List past events sorted by date"
- "Find unpublished draft events this month"
What is the Sympla MCP server, and what's possible with it?
The Sympla MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Sympla account. It provides structured and secure access to your event management data, so your agent can perform actions like listing events, filtering by status, sorting results, and accessing event details on your behalf.
- Comprehensive event listing: Ask your agent to fetch a complete list of all events you've created, streamlining your event management process.
- Status-based event filtering: Easily filter your events by published status, so you can quickly find ongoing, upcoming, or draft events.
- Custom event sorting: Sort your event listings by date, name, or other supported criteria for easier review and management.
- Access detailed event information: Let your agent retrieve key event details to help with monitoring, reporting, or planning tasks.
Conclusion
You've successfully integrated Sympla with Codex using Composio's MCP server. Now you can interact with Sympla 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 Sympla operations
- Managed authentication through Composio
- Access to 20,000+ tools across 1700+ apps for cross-app workflows
- CodeAct workbench for complex tool chaining
Next steps:
- Try asking Codex to perform various Sympla 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 Sympla MCP server, the agents and LLMs can only access a fixed set of Sympla tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Sympla 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 Sympla tools.
Yes, absolutely. You can configure which Sympla 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 Sympla data and credentials are handled as safely as possible.
