Read Everything in Codex

Use Everything as an external reference when working in Codex.

Add the MCP server

Run this command in a terminal with Codex installed:

codex mcp add everything --url https://everything.emlynoregan.com/mcp/

Check that Codex recognises it:

codex mcp list

Alternatively, put the following in ~/.codex/config.toml, adding it to any existing configuration rather than replacing other servers:

[mcp_servers.everything]
url = "https://everything.emlynoregan.com/mcp/"

The Codex CLI and IDE integration use the shared configuration. Reload your client if necessary.

Try it

Use the Everything MCP get_page tool to read /topics/software-and-agents. What is the title, and which collection does it introduce?

A successful read identifies Software & Agents and Beyond the Application. Check the real tool result rather than trusting a plausible answer.

Now try asking Codex to compare two articles, trace a concept through related pages, or discuss an Everything essay in relation to your own code.

Visitors have read-only access. No Everything login, API key or local server is needed. Your Codex account may have its own access requirements.

See OpenAI's Codex MCP example for current commands.
