Sandwich
The platform for the sandwich generation — caring for aging parents while raising kids.
Sandwich helps families coordinate eldercare, organize what their parents
need, and pay for it without burning out. We also expose our care
directory and family workspace as agent-callable tools so AI
assistants like Claude, Cursor, and ChatGPT can answer real questions
about Medicare, Medicaid, long-term care insurance, and the cost of
care in any U.S. state.

What is the sandwich generation?
Adults caring for an aging parent and raising children at the same
time. Roughly 1 in 4 Americans aged 40–59 are in this position
(Pew, 2024).
Sandwich is built around the 40-70 rule: when you turn 40 or your
parents turn 70, it's time to start the conversation about Medicare,
power of attorney, advance directives, and long-term-care plans.
We cover:
- Legal — power of attorney, advance directives, guardianship,
estate planning
- Financial — Medicare and Medicaid, long-term care insurance,
the 5-year Medicaid look-back, IRMAA, RMDs
- Healthcare — home care, adult day, assisted living, memory
care, nursing home, hospice
- Cost projections — state-by-state, 1–30 year horizons, custom
inflation assumptions, sourced from the CareScout 2025 Cost of
Care Survey
- Family logistics — shared calendars, medication tracking,
caregiver coordination, secure messaging
For AI agents and developers
Sandwich exposes two MCP servers registered with the official
Model Context Protocol Registry.
Any MCP-capable agent — Claude Desktop, Claude Code, Cursor, custom
agents — can call them.
