What is the Circadian REM Sleep Cycle Optimizer MCP Server?
Managing sleep debt requires biological precision. Artificial Intelligence models generally lack an understanding of human circadian rhythms, suggesting arbitrary '8 hours of sleep' that interrupt deep REM phases and cause morning grogginess. The Circadian REM Optimizer processes strict chronobiology rules natively.
Core Value Add
- REM Phase Harmonization: Computes exact timestamps mapped to natural 90-minute sleep cycles (from 3 to 6 cycles), ensuring you always wake up during light sleep stages.
- Latency Buffering Engine: Standard sleep math ignores sleep latency. This MCP integrates an adjustable 'fall asleep' buffer (default 15 minutes) into the backward/forward timeline progression.
- Bidirectional Architecture: Supports both 'wake_up_at' (backward deduction) and 'sleep_at' (forward projection) modes to fit rigid alarm schedules or flexible weekend chronotypes.
- Zero-Dependency Native Code: The mathematical projection happens securely within the V8 engine, maintaining high-speed responsiveness for health-tech AI workflows.
Built-in capabilities (4)
Maps out energy peaks and troughs throughout the day based on wake time
Requires wake-up time in HH:mm. Calculates the ideal window for power naps based on wake-up time
Provide a targetTimeStr (HH:mm) and the mode (sleep_at or wake_up_at). Calculates optimal wake-up or bedtimes aligned with 90-minute REM sleep phases, incorporating latency buffers for circadian rhythm optimization
Requires daily required hours and an array of actually slept hours. Calculates accumulated sleep debt and provides an actionable recovery strategy
Why Cursor?
Cursor's Agent mode turns Circadian REM Sleep Cycle Optimizer into an in-editor superpower. Ask Cursor to generate code using live data from Circadian REM Sleep Cycle Optimizer and it fetches, processes, and writes. all in a single agentic loop. 4 tools appear alongside file editing and terminal access, creating a unified development environment grounded in real-time information.
- —
Agent mode turns Cursor into an autonomous coding assistant that can read files, run commands, and call MCP tools without switching context
- —
Cursor's Composer feature can generate entire files using real-time data fetched through MCP. no copy-pasting from external dashboards
- —
MCP tools appear alongside built-in tools like file reading and terminal access, creating a unified agentic environment
- —
VS Code extension compatibility means your existing workflow, keybindings, and extensions all work alongside MCP tools

Frequently asked questions
What is the 90-minute REM rule?
Human sleep cycles last approximately 90 minutes. Waking up in the middle of a deep REM phase causes 'sleep inertia' (grogginess). This algorithm targets wake-up times strictly at the end of a cycle, meaning sleeping 7.5 hours (5 cycles) often feels more refreshing than sleeping 8 hours.
Why use an MCP for sleep math?
Because calculating multiple backward chronobiological subtraction paths in base-60 time causes frequent LLM errors. By offloading it to this deterministic timeline engine, the calculations are mathematically flawless.
Does it account for the time it takes to fall asleep?
Yes. The algorithm incorporates a 'fallAsleepBufferMinutes' parameter (which defaults to 15 minutes). If you need to wake up at 07:00, the 5-cycle target recommends getting into bed at 23:15, allowing exactly 15 minutes to fall asleep before the cycles commence.
What is Agent mode and why does it matter for MCP?
Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.
Where does Cursor store MCP configuration?
Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.
Can Cursor use MCP tools in inline edits?
No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.
How do I verify MCP tools are loaded?
Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
Tools not appearing in Cursor
Ensure you are in Agent mode (not Ask mode). MCP tools only work in Agent mode.
Server shows as disconnected
Check Settings → Features → MCP and verify the server status. Try clicking the refresh button.
