Who it is for
Anyone having trouble falling asleep who is already in a late-night conversation.

Relaxing audio started from within a conversation
Overview
This app covers one part of what Sleep Cycle makes: the audio. Sounds put together to help a listener relax and drift off can be started on request.
The company describes its tools as grounded in sleep science. The practical effect in chat is narrow and immediate. When winding down is proving difficult, playback begins in the conversation itself instead of after opening a separate app.
The two example prompts match that scope. One asks for help falling asleep, the other simply asks what the app can do. Nothing in the published record describes tracking, alarms, or sleep reporting through this connector, so the sound library is the whole of it.
Anyone having trouble falling asleep who is already in a late-night conversation.
The scope is deliberately small, with audio playback available without leaving the chat.
Availability
Sleep Cycle is listed in the ChatGPT apps directory only. Sleep Cycle AB has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.

This is an independent catalogue entry compiled by Node8 from Sleep Cycle's public marketplace listing as it stood in August 2026. Listing facts come from the marketplaces; the comparisons against the rest of the directory and any live-endpoint measurements are Node8's. Node8 is not affiliated with Sleep Cycle AB, and inclusion here is not an endorsement.
Node8 builds MCP servers end to end: deciding which tools are worth exposing, the authentication and permission model, the review submissions, and the onboarding that gets them used. One server serves ChatGPT, Claude, and Microsoft Copilot.
