  "markdown": "# Sandwich\n\n**The platform for the sandwich generation — caring for aging parents while raising kids.**\n\nSandwich helps families coordinate eldercare, organize what their parents\nneed, and pay for it without burning out. We also expose our care\ndirectory and family workspace as **agent-callable tools** so AI\nassistants like Claude, Cursor, and ChatGPT can answer real questions\nabout Medicare, Medicaid, long-term care insurance, and the cost of\ncare in any U.S. state.\n\n🌐 **Marketing site:** [joinsandwich.com](https://www.joinsandwich.com)\n👨‍👩‍👧 **Family app:** [app.joinsandwich.com](https://app.joinsandwich.com)\n🤖 **Agent integration docs:** [app.joinsandwich.com/agents](https://app.joinsandwich.com/agents)\n📦 **MCP Registry:** [`com.joinsandwich/directory`](https://registry.modelcontextprotocol.io/v0.1/servers?search=com.joinsandwich) · [`com.joinsandwich/care-circle`](https://registry.modelcontextprotocol.io/v0.1/servers?search=com.joinsandwich)\n\n---\n\n## What is the sandwich generation?\n\nAdults caring for an aging parent **and** raising children at the same\ntime. Roughly **1 in 4** Americans aged 40–59 are in this position\n([Pew, 2024](https://www.pewresearch.org/social-trends/2024/09/29/the-sandwich-generation/)).\nSandwich is built around the **40-70 rule**: when you turn 40 or your\nparents turn 70, it's time to start the conversation about Medicare,\npower of attorney, advance directives, and long-term-care plans.\n\nWe cover:\n\n- **Legal** — power of attorney, advance directives, guardianship,\n  estate planning\n- **Financial** — Medicare and Medicaid, long-term care insurance,\n  the 5-year Medicaid look-back, IRMAA, RMDs\n- **Healthcare** — home care, adult day, assisted living, memory\n  care, nursing home, hospice\n- **Cost projections** — state-by-state, 1–30 year horizons, custom\n  inflation assumptions, sourced from the CareScout 2025 Cost of\n  Care Survey\n- **Family logistics** — shared calendars, medication tracking,\n  caregiver coordination, secure messaging\n\n---\n\n## For AI agents and developers\n\nSandwich exposes **two MCP servers** registered with the official\n[Model Context Protocol Registry](https://registry.modelcontextprotocol.io).\nAny MCP-capable agent — Claude Desktop, Claude Code, Cursor, custom\nagents — can call them.\n\n### `com.joinsandwich/directory` — public, no auth\n\nRead-only research tools for the 840+ vetted resources and the cost\ncalculator.
