Using Codex

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

• You have access to DataDoe and a working MCP-capable agent or client.
• You know where that agent stores its MCP server configuration.

Step 1: Add the DataDoe MCP server

Add the DataDoe MCP server to the Codex project or workspace configuration that your session reads on startup.

In order to add DataDoe MCP to Codex configuration, add this to ~/.codex/config.toml or .codex/config.toml (for project-specific configuration):

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

Step 2: Reload the agent

Restart the agent so it picks up the new MCP server definition.

Step 3: Test it

Run your first prompt, for example: Show me all sellers and vendors from DataDoe.
