Use Piply in Codex
Codex reads its MCP servers from one config file and signs in with a single command. Add Piply and you can turn your lecture notes into practice without leaving the terminal.

Illustrative prompt. After connecting, check the source references and any saved result in Piply. This example is not a record of a completed tool call.
Account access and review
Sign-in authorizes the connection to your Piply account under the permissions you approve. Asking about one file does not restrict access to that file. Review the host’s tool controls and check generated content against your materials. Disconnecting does not retract information already sent to the host.
What you need
- Codex CLI installed and signed in (recent versions support remote MCP).
- A Piply account (free).
Connect Piply to Codex
Documentation checked . Official setup documentation.
- 1 Run the two commands below.

The commands add a Streamable HTTP MCP server and then complete OAuth sign-in.
Codex CLI and IDE extension share MCP configuration. User settings live in ~/.codex/config.toml; trusted projects can use .codex/config.toml.
What Codex can do with Piply
These tasks need a client that can call the relevant Piply tools and your approved permissions. Saving requires a course you created; shared and public courses are read-only. Ask the host to use Piply, then check its response and any saved result.
