Summary
This is the authenticated companion to Sandwich's public directory server. Once you generate a Bearer token from your family workspace, you can read care events (appointments, meds, visits, notes), list loved ones in your care circle, and inspect your tenant context. It's designed for HIPAA compliance with per-key rate limits and append-only audit logs. Use it when you want Claude or another MCP client to answer questions about your specific family's care schedule rather than general Medicare or cost-of-care research. The four tools are ping, get_user_profile, list_loved_ones, and list_care_events. Runs on streamable-http at app.joinsandwich.com/api/mcp with full OAuth 2.1 support if you need something beyond static keys.

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
