Cursor uses the same mcpServers schema as Claude Desktop. Project config wins over global.

Continue uses an array of server objects rather than a map.

Add to context_servers. Zed hot-reloads on save.

Use Cases

Real-world ways to use health-skillz

Ask plain questions about your lab result trends

👤 Patients tracking chronic conditions, cholesterol, A1c ⏱ ~15 min beginner

When to use: You've had repeated labs over months/years and want to see the trajectory, not just each result in isolation.

Prerequisites

A patient portal with FHIR access — Most major US health systems support SMART on FHIR — check your portal for API/app access
Skill installed — git clone https://github.com/jmandel/health-skillz ~/.claude/skills/health-skillz

Flow

Authenticate

Use health-skillz to connect to my Epic MyChart account.✓ Copied

→ Browser opens SMART launch; token stored locally
Pull labs

Show my LDL, HDL, and A1c over the past 3 years as a trend.✓ Copied

→ Time-series table or summary with unit conversions
Contextualize

Relate these to the guideline ranges. Don't give me medical advice — just surface what's in range vs not.✓ Copied

→ Explicit framing as reference ranges, not diagnosis

Outcome: A readable longitudinal view of your key labs — useful before your next appointment.

Pitfalls

Treating Claude's output as medical advice — Always bring questions to your actual clinician. This skill is for understanding your own records, not a second opinion.

Reconcile the medication list before an appointment

👤 Patients on multiple meds from multiple providers ⏱ ~10 min beginner

When to use: You're about to see a new specialist and want a clean, current med list.

Flow

Fetch active meds

Use health-skillz. Pull my current medication list with dose, frequency, and prescribing provider.✓ Copied

→ Structured list with RxNorm codes resolved to names
Spot duplicates and gaps

Any duplicate therapy, same-class redundancies, or meds that look expired?✓ Copied

→ Flags you can raise with your doctor

Outcome: A med list to hand your new provider on day one.

Pitfalls

Portals sometimes miss OTC meds — Supplement manually; the portal only shows what was prescribed via it

Export a relevant subset of records for a new specialist

👤 Patients changing providers or seeing a specialist ⏱ ~20 min intermediate

When to use: You're consolidating records for a second opinion.

Flow

Filter

Use health-skillz. Pull all cardiology-related encounters, labs, and imaging from the last 2 years.✓ Copied

→ Filtered export grouped by encounter
Format

Format as a one-page summary a specialist can skim in 30 seconds.✓ Copied

→ Compact doc with key dates, diagnoses, pertinent findings

Outcome: A portable summary you own — not a 200-page PDF dump.

Pitfalls

Losing nuance by summarizing — Always bring the full export as backup; summary is for quick triage

Combine with: filesystem

Combinations

Pair with other MCPs for X10 leverage

health-skillz-skill + filesystem

Save exports to an organized local folder structure

Save the cardiology export to ~/health/specialists/cardio-2026.md✓ Copied

Tools

What this MCP exposes

Tool	Inputs	When to call	Cost
smart_launch	provider URL	First-time connection to a provider	OAuth redirect
get_observations	patient id, category, date range	Pulling labs or vitals	FHIR API call
get_medications	patient id, status	Med reconciliation	FHIR API call
get_encounters	patient id, date range	Visit history review	FHIR API call

Cost & Limits

What this costs to run

API quota: Depends on the provider's FHIR API limits
Tokens per call: Moderate — lab results are compact
Monetary: Free (portal access is included with care)
Tip: Pull in one category at a time; full 'everything' exports are token-expensive.

Security

Permissions, secrets, blast radius

Minimum scopes: patient/*.read

Credential storage: OAuth token in local credential store; never committed

Data egress: Your FHIR server and Anthropic API only

Never grant: user/*.write system/*.*

This is NOT medical advice. The skill surfaces your own records; decisions remain with you and your clinicians.
Health data is sensitive. Understand that by querying via Claude, excerpts of your records are sent to Anthropic's API per their data policies.
Revoke the app's access from your patient portal when you're done.

Troubleshooting

Common errors and fixes

SMART launch fails with redirect error

Most portals require pre-registering the app's redirect URI. Check the skill's docs for your provider.

Empty results despite having data in portal

Your provider may restrict FHIR scopes; try narrower queries or contact support.

Lab codes show as raw LOINC IDs

Ensure the skill's code map is current; may need to update the clone.

Verify: cd ~/.claude/skills/health-skillz && git pull

Alternatives

health-skillz vs others

Alternative	When to use it instead	Tradeoff
Manual portal export	One-time export of all records	PDF dump, not queryable
Apple Health app	iOS-centric consumer aggregation	Closed data; no LLM querying
