Private health intelligence layer

CareVault

Your health data becomes a living map — one that reasons across itself.

CareVault pulls the scattered pieces of your health into one controlled record — labs, biomarkers, medications, wearables, imaging, notes, and care dates — then does what a folder never could: correlates two signals, measures a medication's before/after impact, aligns every series onto one timeline, and reconciles units across sources. It runs on your own machine and works with any AI. No portal archaeology. No silent gaps. No silos.

Cross-signal reasoning · new

Insight lives between the signals.

Any record can store a lab result. CareVault's newest layer reasons about relationships — the part where health insight actually hides. It aligns any two signals onto a common footing and returns real statistics, always descriptive, never a diagnosis.

ρcorrelate_metrics

Pearson & Spearman between any two signals — weight against A1C, sleep against resting heart rate — aligned on a shared day, week, or month grid, with paired sample size, a two-sided p-value, and honest caveats about small samples and autocorrelation.

Δanalyze_event_impact

Anchor a metric to a discrete event — a medication start, a procedure — and get before/after descriptive stats plus a Welch t-test on the change, with an optional washout gap to skip the transition.

align_series

Resample many signals onto one shared time grid — one row per bucket, one column per signal — so any two line up without hand-matching a single timestamp.

unormalize_series

Reconcile units and reference ranges across labs and devices — mg/dL ↔ mmol/L via analyte molar mass — and add a unitless in-range position so results from different labs finally compare.

Health trajectory

The record stops being a folder.

Every dated detail becomes part of the same path. A medication change can sit beside a lab shift. A sleep baseline can explain a symptom window. A follow-up stops being a memory burden and becomes part of the map.

Record model

Every health signal gets a lane.

CareVault is not a prettier PDF drawer. It gives each kind of health data a structured place to live, then connects the pieces by date, source, and meaning — so the reasoning layer has something real to reason over.

A
Bloodwork becomes trendable.

A report is stored as metadata plus individual results, so LDL, A1C, CRP, vitamin D, and other analytes can become timelines.

result_datenumeric_valueref_range
Reference ranges stay attached.

Units, flags, specimen, lab name, ordering provider, and source notes remain part of the record — ready to normalize across labs.

Assistant-ready, not assistant-owned.

The MCP can search, summarize, correlate, measure event impact, align, normalize, and export the data without hiding the structure.

Whole-record coverage

Health is not one data type.

The underlying HealthLedger MCP is a local-first, model-agnostic server exposing 72 structured tools: broad capture across clinical history, high-volume wearable samples, care tasks, documents, reproductive records, substance logs, and oncology — plus a cross-signal layer that reasons over all of it.

B

Bloodwork

Lab reports, individual results, flags, units, reference ranges, and descriptive trends.

M

Medications

Active meds, dose logs, schedules, instructions, refill dates, and adherence history.

W

Wearables

HRV, sleep, resting heart rate, steps, SpO2, workouts, temperature, CGM-style samples, and scales.

O

Oncology

Tumor records, body site, stage, grade, marker summaries, treatment status, and notes.

P

Physicals

Encounters, annual visits, procedures, imaging, immunizations, follow-ups, and care tasks.

D

Documents

Reports, notes, attachments, source metadata, search, and exportable record pages.

F

Family and life context

Family history, reproductive records, substance logs, profile facts, and user goals.

Σ

Cross-signal

Correlate two signals, measure event impact, align many series, and normalize units and ranges.

Control layer

You are the source of truth.

CareVault treats the assistant as a reader and operator over your record, not the owner of it. The data model stays explicit, exportable, and inspectable — and every analysis stays descriptive.

No silos.

Labs, doctors, pharmacies, devices, notes, imaging, and documents converge into one private longitudinal record.

search_records → all domains

Signals, related.

Any two series align on a shared grid, so a correlation, a before/after change, or a unit reconciliation is one call away.

correlate_metrics → weight × A1C

Useful dates.

Refills, follow-ups, labs due, stale data, immunizations, and unresolved tasks become a single care agenda.

health_agenda → next 30 days

Local-first · model-agnostic · open source

A new way to think about your health data.

Not another portal. Not a hosted account. CareVault is the surface for a personal health ledger you run yourself — a local MCP server that keeps your data in a file on your own machine and works with any AI client and any model. Install it, point your assistant at it, and start reasoning over your own record.

A single-tenant live demo runs at health-mcp.manticthink.com/mcp — to actually use it, self-host your own from GitHub.
