The Codex app, IDE extension and CLI share one settings file, so you set this up once.
Add the server#
codex mcp add mr-market --url https://mrmarket.fyi/mcpSign in#
codex mcp login mr-marketYour browser opens Mr. Market's sign-in. Sign in and choose Allow, then restart Codex.
Check it:
codex mcp listmr-market should be listed as enabled. In Codex, ask: What can you look up with mr-market? Call about.
The same thing in config.toml#
codex mcp add writes this to ~/.codex/config.toml:
[mcp_servers.mr-market]
url = "https://mrmarket.fyi/mcp"Skills#
Install the workflows as Agent Skills so Codex can use them:
npx skills add https://docs.mrmarket.fyiRemove it#
codex mcp remove mr-marketThen disconnect it in Account.
