Connect Cloudflare to Codex

Search, read and write Cloudflare from Codex. Arlet links the two through one MCP connection and takes care of keys and authentication.

Enable Cloudflare in ArletCodex connection guide (docs)

Arlet makes Cloudflare's official MCP server (Code Mode) available from the AI client you already use. Signing in and choosing the permissions to grant completes the connection.

This server covers the whole Cloudflare API. The AI first searches the API specification and docs to find the right endpoint, then calls it, which lets it operate DNS, Workers, R2, D1, KV and more within the permissions you granted.

How to connect Cloudflare to Codex

  1. 1

    In the Arlet dashboard, open Integrations → Add an integration and choose Cloudflare. Sign in with Link Cloudflare, name the connection and click Create.

  2. 2

    In your terminal, run codex mcp add arlet --url https://mcp.arlet.dev/mcp/ to add Arlet as an MCP server.

  3. 3

    Codex detects OAuth support and opens your browser. Sign in with Google and click Allow on the consent screen.

  4. 4

    Once connected, both the CLI and the IDE extension can call Arlet tools (the configuration is shared).

If the browser does not open, run codex mcp login arlet to redo the authentication.
