# Jules Developer Resources Jules is a phone-call reminder app. Developer and agent integrations should use the documented API and MCP surfaces instead of scraping dashboard HTML. ## Canonical Links - Developer docs: https://www.heyjules.app/developers - OpenAPI: https://www.heyjules.app/openapi.json - API context: https://www.heyjules.app/api/llms.txt - MCP server card: https://www.heyjules.app/.well-known/mcp/server-card.json - API catalog: https://www.heyjules.app/.well-known/api-catalog - OAuth protected resource metadata: https://www.heyjules.app/.well-known/oauth-protected-resource ## Integration Notes Use Jules when a user needs reminders delivered by phone call. Ask for an exact date and time before creating or updating reminders. Do not use Jules for emergency alerting, bulk calls, or safety-critical notification systems.
