Introduction

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

Also integrate New relic 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 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 New relic 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 New relic MCP server, and what's possible with it?

The New Relic MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your New Relic account. It provides structured and secure access to your observability data and alerting infrastructure, so your agent can perform actions like retrieving application metrics, managing alert policies, updating notification channels, and monitoring browser applications on your behalf.

  • Comprehensive alert policy management: Effortlessly create, update, or delete New Relic alert policies to keep your monitoring rules current and effective.
  • Alert notification channel control: Register new alert endpoints, update existing channels, or list all notification channels to optimize how your team receives important alerts.
  • Real-time application monitoring: Instantly retrieve a list of all monitored applications, filter them by name or host, and stay on top of your software stack’s health.
  • Browser application insights: List and filter browser applications to monitor user experience and catch frontend issues before they escalate.
  • Alert condition visibility: Fetch detailed alert conditions for specific policies, so you can audit or fine-tune how your system responds to incidents.

How to build New relic MCP Agent with another framework

FAQ

What are the differences in Tool Router MCP and New relic MCP?

With a standalone New relic MCP server, the agents and LLMs can only access a fixed set of New relic tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from New relic 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 New relic tools.

Can I manage the permissions and scopes for New relic while using Tool Router?

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