Introduction

Codex is one of the most popular coding harnesses out there. And MCP makes the experience even better. With Launch darkly MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer.

Also integrate Launch darkly with

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 Launch darkly 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 connect.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 Launch darkly MCP server, and what's possible with it?

The Launch darkly MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Launch darkly account. It provides structured and secure access to your feature management platform, so your agent can perform actions like managing feature flag workflows, listing projects, retrieving environments, and reviewing teams or custom roles.

  • Automated flag trigger workflows: Set up, modify, or delete flag trigger workflows so your agent can help automate feature releases and rollbacks in specific environments.
  • Comprehensive project and environment listing: Instantly retrieve all projects and their environments to help your agent audit, enumerate, or manage deployment contexts.
  • Team and role audits: List all teams and custom roles, making it easy for your agent to review permissions, conduct audits, or suggest configuration changes.
  • Code reference repository discovery: Pull complete lists of code reference repositories tied to your projects for better traceability and DevOps integration.
  • Effortless environment and project management: Quickly access and enumerate environments and projects to streamline workflows and improve operational oversight.

Conclusion

You've successfully integrated Launch darkly with Codex using Composio's MCP server. Now you can interact with Launch darkly 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 Launch darkly operations
  • Managed authentication through Composio
  • Access to 20,000+ tools across 870+ apps for cross-app workflows
  • CodeAct workbench for complex tool chaining

Next steps:

  • Try asking Codex to perform various Launch darkly operations
  • Explore cross-app workflows by connecting more toolkits
  • Build automation scripts that leverage Codex's AI capabilities

FAQ

What are the differences in Tool Router MCP and Launch darkly MCP?

With a standalone Launch darkly MCP server, the agents and LLMs can only access a fixed set of Launch darkly tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Launch darkly and many other apps based on the task at hand, all through a single MCP endpoint.

Can I use Tool Router MCP with Codex?

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 Launch darkly tools.

Can I manage the permissions and scopes for Launch darkly while using Tool Router?

Yes, absolutely. You can configure which Launch darkly 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.

How safe is my data with Composio Tool Router?

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 Launch darkly data and credentials are handled as safely as possible.
