Api Key

Paradym is an API-first platform for issuing, verifying, and managing verifiable credentials. It streamlines credential workflows using standards like SD-JWT VCs and AnonCreds.

Introduction

Codex is one of the most popular coding harnesses out there. And MCP makes the experience even better. With the Paradym MCP integration, Codex can issue verifiable credentials, create credential templates, send verification requests, manage DIDComm connections, and track issuance sessions, all without leaving the terminal or the app, whichever you prefer.

For exact tool slugs and parameter tables, see the tool catalog in the Composio docs.

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 Paradym 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_*******" }

Try it

Ask Codex for a Paradym task. The first time, Composio asks you to connect your Paradym account.

For example, ask it to:

  • "Issue SD-JWT verifiable credential for a user"
  • "Verify authenticity of a presented credential"
  • "List all credentials issued to an email address"

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

The Paradym MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Paradym account. It provides structured and secure access to your verifiable credential workflows, so your agent can perform actions like issuing credentials, verifying identity claims, managing credential lifecycles, and supporting interoperability across digital identity standards.

  • Automated credential issuance: Instruct your agent to issue new verifiable credentials to users or systems, supporting protocols like SD-JWT VCs and AnonCreds.
  • Seamless credential verification: Enable your agent to verify the authenticity and validity of credentials presented by others, streamlining onboarding and trust checks.
  • Credential lifecycle management: Allow your agent to update, revoke, or renew existing credentials, ensuring full control over your digital identity assets.
  • Interoperability with identity standards: Leverage your agent to work across OpenID4VC, DIDComm, and other standards for maximum compatibility and flexibility.
  • Audit and usage tracking: Task your agent to retrieve detailed logs or status reports on credential activity, helping you maintain compliance and visibility.

Conclusion

You've successfully integrated Paradym with Codex using Composio's MCP server. Now you can interact with Paradym 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 Paradym 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 Paradym operations
  • Explore cross-app workflows by connecting more toolkits
  • Build automation scripts that leverage Codex's AI capabilities
