Using Codex with DataDoe MCP

Use Codex when you want an agent that can generate or change code while also reading live DataDoe context through MCP.

Prerequisites

• Codex CLI (opens in a new tab) installed and signed in.
• A DataDoe MCP key. Create one in DataDoe MCP Integrations (opens in a new tab).

Step 1: Add the DataDoe MCP server

Add this to ~/.codex/config.toml (global) or .codex/config.toml (project-scoped):

1[mcp_servers.datadoe]
2url = "https://mcp.datadoe.com/mcp/v1"
3http_headers = { "datadoe-mcp-key" = "YOUR_API_KEY" }
4startup_timeout_sec = 30

Replace YOUR_API_KEY with your DataDoe MCP key.

Step 2: Reload Codex

Restart your Codex session so it picks up the new MCP server.

Step 3: Test the connection

Run a prompt that uses DataDoe data, for example:

Show me my Amazon Seller Central sales for the last 7 days.

If Codex returns real data, you're connected.
