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 870+ 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 Waiverfile 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.
Verify the connection
Run codex mcp list to confirm Composio appears as a registered MCP server.
Codex 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 connect.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
What is the Waiverfile MCP server, and what's possible with it?
The Waiverfile MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Waiverfile account. It provides structured and secure access to your waiver management system, so your agent can retrieve site metadata, streamline waiver processing, and help automate parts of your waiver operations.
- Fetch site metadata instantly: Quickly pull public details about your Waiverfile site, such as site name, branding, and basic information for easy reference or display.
- Automate waiver form discovery: Let the agent access information about available waiver forms, ensuring up-to-date options for customers or event participants.
- Centralize waiver management tasks: Enable your agent to quickly verify site details and readiness before sending out waivers or collecting signatures.
- Integrate site data with other workflows: Seamlessly connect Waiverfile site info with your existing tools or dashboards for smoother event and customer management.
