Codex

Ask Codex to connect. You only need to complete sign-in in your browser.

Ask your agent

Install PubCoDB using https://pubcodb.com/connect/codex. Reuse an existing connection if present. Guide me through sign-in, then find Toyota’s three latest filings.

Setup

Have Codex read this page, or run the commands below with Node.js 18 or newer and the Codex CLI installed.
The installer checks existing connections, adds PubCoDB only if needed, and starts native OAuth sign-in.
Complete sign-in using the same PubCoDB account you use elsewhere.
Start a fresh Codex session if the tools are not visible.

curl --fail --show-error --location https://pubcodb.com/install.mjs --output pubcodb-install.mjs
node pubcodb-install.mjs --client codex

Environment: Production

MCP server: https://pubcodb.com/mcp

Check the connection

Call research_help, resolve Toyota’s Japan listing, and return its three latest filings with dates and source links. Configuration alone does not confirm access.

Add --check to inspect without changing anything. Codex starts sign-in when adding a server; --no-login only works for an existing connection. Older better-filings names are reused. Do not paste credentials into chat.

OpenAI: MCP in Codex

Same account

Use the same PubCoDB sign-in in every client. Your account, plan, monthly allowance, API keys, and watchlists remain attached to that account.
