Connect Codex to Beamline

Beamline's MCP server: https://mcp.beamline.io/mcp (remote, Streamable HTTP, OAuth sign-in).

  1. Add the server. In any terminal.
    codex mcp add beamline --url https://mcp.beamline.io/mcp
  2. Sign in. Opens your browser: Google, GitHub or an e-mail code.
    codex mcp login beamline
  3. Connect each app. Once per app folder. Every later session there uses Beamline without being asked.
    npx --yes -p https://mcp.beamline.io/cli.tgz beamline-connect --hosted https://mcp.beamline.io/mcp

Or send Codex this message

Set up Beamline for this app, so you build its UI from Beamline's React components.
1. Add the MCP server: run `codex mcp add beamline --url https://mcp.beamline.io/mcp`.
2. Sign in: run `codex mcp login beamline` and ask me to finish in the browser it opens (Google, GitHub or an e-mail code).
3. Connect this app: in its folder, run `npx --yes -p https://mcp.beamline.io/cli.tgz beamline-connect --hosted https://mcp.beamline.io/mcp`.
4. Tell me to start a new Codex session in this app: it loads the tools. From then on, call beamline_capabilities before any UI work.

Then your agent reads what each of Beamline's 190 React components and screens is for (beamline_capabilities), installs only the parts a screen needs into your repo (beamline_install), as a ready-built package or as plain React source, and checks the result. Sign in once with Google, GitHub or an e-mail code: the free sample opens at once, and what your team bought comes with you.
