Install Azure FinOps MCP Server in Codex

What you need first

• Codex, installed.
• uv, which gives the uvx command the server starts with.
• Your own values for YOUR_AZURE_ALLOWED_SUBSCRIPTIONS,YOUR_AZURE_DEFAULT_SUBSCRIPTION.

Steps

1. Run this in a terminal. It writes the server into ~/.codex/config.toml, which the Codex CLI, its IDE extension and the ChatGPT desktop app share.

codex mcp add azure-finops-mcp --env AZURE_ALLOWED_SUBSCRIPTIONS=YOUR_AZURE_ALLOWED_SUBSCRIPTIONS --env AZURE_DEFAULT_SUBSCRIPTION=YOUR_AZURE_DEFAULT_SUBSCRIPTION -- uvx azure-finops-mcp==0.1.1

2. Replace YOUR_AZURE_ALLOWED_SUBSCRIPTIONS,YOUR_AZURE_DEFAULT_SUBSCRIPTION with your own values.
3. Start Codex again and type /mcp: the server is listed.

Check it worked

Ask Codex: List the tools of azure-finops-mcp.

If it does not start

spawn uvx ENOENT

uv is not on the PATH that Codex sees. Install it, or write the full path of uvx in the config.

The server starts, but its tools fail

A YOUR_… placeholder is still in the config, or its value is wrong.
