The Oura MCP Server is a Model Context Protocol server that exposes the Oura API to language models and other MCP clients. It enables querying sleep, readiness, and resilience data from the Oura API via simple MCP tools. The server provides date range queries (get_sleep_data, get_readiness_data, get_resilience_data) that accept start_date and end_date in ISO format (YYYY-MM-DD), as well as today-specific queries (get_today_sleep_data, get_today_readiness_data, get_today_resilience_data). To use it, you must supply an Oura API Personal Access Token, typically via the OURA_API_TOKEN environment variable. The README also demonstrates Claude Desktop integration, showing how to configure Claude to invoke the server. Error handling is designed to produce human-readable messages for common issues such as invalid date formats, authentication errors, and network problems. Dates must be provided in ISO format. The project emphasizes easy integration for AI assistants and language models to access personal wearables data safely when authenticated.
