Getting Started with Cue
Build a private prompt library and use it through ChatGPT, MCP clients, or compatible agent CLIs.
Cue is a private library for the prompts and reusable instructions you reach for often. Save the complete instruction once, then let ChatGPT, an MCP client, or a compatible CLI agent find it when you need it. There is nothing to install on every machine and no template syntax to maintain.
Create your account
Create a Cue account with your email and password, then verify your address if Cue asks you to. Sign in with the same account wherever you connect your library so the prompts stay private to you.
Save your first Cue
Open Cues in the dashboard and add an instruction you genuinely reuse. Give it a clear, action-oriented title, such as “Research a SaaS idea” or “Turn notes into a launch brief.” Paste the full prompt as you would want an agent to receive it.
Cue does not require variables or a complicated command format. Let the agent combine the saved instruction with the current conversation and the details you give it at the moment of use.
Make the library easy to search
Use a short description to record when the Cue helps, then add a few specific tags. Good tags describe a job or context—research, product, writing, or weekly-review—rather than trying to classify every sentence.
Treat titles as the words you would naturally ask for later. This makes it easier for an agent to find the right Cue without you memorizing a command.
Improve a Cue without losing its history
Update a Cue when you learn a better way to frame the work. Cue keeps a versioned history, so your library can evolve while the current version remains the one your connected tools use.
Keep sensitive values out of the prompt itself. Store only reusable instructions; provide account details, private data, and one-off context directly in the conversation where you use the Cue.
Connect it where you work
Open Integrations in Cue to find your personal MCP endpoint. Add that endpoint to a supported ChatGPT connection, MCP client, or agent CLI, then sign in and approve read access. The client can search your library and retrieve the complete text of a Cue when it is relevant.
You only need to maintain the prompt in Cue. After that, the same library is available wherever you have connected it.
Keep going
Start with a handful of prompts you already use every week. As you notice repeated work, save the instruction as a Cue, give it a searchable title, and refine it over time. A small, trusted library is more useful than a large collection you cannot find.
