Comprehensive Model Context Protocol server for managing Home Assistant through AI assistants.
Quantified Self is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.
What it does
Local-first MCP server for personal health data with privacy, statistical evidence, and provenance.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user quantified-self-mcp '--' uvx quantified-self-mcp
# 2 — ask your agent for something these tools do
# get_metric_history, get_baseline, detect_metric_anomalies and 17 more
Quantified Self costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.
Collected from a public index. Nobody has claimed this account, so nothing here was written by its author — claim it if it is yours.
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. This one runs on your machine: your client starts Quantified Self as a process under your own user, with your files and your network, so the tool surface below is what it can do to your computer rather than to a server somewhere else. Its scan result is on the Security tab — read the surface before you approve it.
This is a public server: you run it yourself and this marketplace is not in the path. You need uv (docs.astral.sh/uv): uvx comes with it. Claude Code registers it in one command; --scope user makes it available in every project. The '--' is in quotes so that PowerShell passes it on.
claude mcp add --scope user quantified-self-mcp '--' uvx quantified-self-mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
One config entry your client uses to start the process locally. A local server runs with your file system and your network, which is why it is priced without metering.
20 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.
Tool surface
What the model actually sees. Descriptions are diffed on every release — see version history.
Read from its source code. A server that builds its tool list when it starts can list more tools than this.
Read one metric's day-by-day values, without the other six metrics read_health_data always includes. Use this when you only care about a single metric (e.g. before calling get_baseline or calculate_metric_trend yourself) and don't need the full multi-metric payload.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| metric | string | yes | One of steps, sleep_hours, resting_heart_rate, weight_kg, workout_minutes, mood, water_ml, heart_rate, hrv_ms. Rejected if configured as private via HEALTH_PRIVATE_FIELDS. |
| start_date | string | no | First day to include, formatted YYYY-MM-DD. Defaults to 30 days before end_date. |
| end_date | string | no | Last day to include, formatted YYYY-MM-DD. Defaults to today. |
Compute "what's normal" for one metric over a window: mean, median, and standard deviation. This is the number every other analytics tool below measures against, so a wider window (60-90+ days) gives a more stable baseline than the 30-day default read_health_data uses.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| metric | string | yes | One of steps, sleep_hours, resting_heart_rate, weight_kg, workout_minutes, mood, water_ml, heart_rate, hrv_ms. |
| start_date | string | no | First day to include, formatted YYYY-MM-DD. Defaults to 90 days before end_date. |
| end_date | string | no | Last day to include, formatted YYYY-MM-DD. Defaults to today. |
Flag days where one metric deviated sharply from its own baseline over the window, using a median/MAD-based modified z-score rather than a mean/stdev z-score — more robust for short, noisy personal-health series, where the mean/stdev version is easily dragged around by the very outliers it's…
| Parameter | Type | Required | Notes |
|---|---|---|---|
| metric | string | yes | One of steps, sleep_hours, resting_heart_rate, weight_kg, workout_minutes, mood, water_ml, heart_rate, hrv_ms. |
| start_date | string | no | First day to include, formatted YYYY-MM-DD. Defaults to 90 days before end_date. |
| end_date | string | no | Last day to include, formatted YYYY-MM-DD. Defaults to today. |
| threshold | number | no | Modified z-score cutoff. 3.5 (the default, Iglewicz & Hoaglin's standard value) flags only clear outliers; lower it (e.g. 2.5) to see more borderline days. |
Fit a simple straight-line trend to one metric over a window and report its direction, slope (change per day), and r_squared (how well a straight line actually fits — low r_squared means "noisy," not "flat").
| Parameter | Type | Required | Notes |
|---|---|---|---|
| metric | string | yes | One of steps, sleep_hours, resting_heart_rate, weight_kg, workout_minutes, mood, water_ml, heart_rate, hrv_ms. |
| start_date | string | no | First day to include, formatted YYYY-MM-DD. Defaults to 30 days before end_date. |
| end_date | string | no | Last day to include, formatted YYYY-MM-DD. Defaults to today. |
Compare one metric's average between two date ranges — e.g. "this month vs. last month" or "since starting a new medication vs. before."
| Parameter | Type | Required | Notes |
|---|---|---|---|
| metric | string | yes | One of steps, sleep_hours, resting_heart_rate, weight_kg, workout_minutes, mood, water_ml, heart_rate, hrv_ms. |
| period_a_start | string | yes | — |
| period_a_end | string | yes | — |
| period_b_start | string | yes | — |
| period_b_end | string | yes | — |
Compute the Pearson correlation between two metrics over the same window, joined by date. Correlation, not causation: a strong r just means the two moved together, not that one caused the other.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| metric_a | string | yes | — |
| metric_b | string | yes | — |
| start_date | string | no | First day to include, formatted YYYY-MM-DD. Defaults to 90 days before end_date. |
| end_date | string | no | Last day to include, formatted YYYY-MM-DD. Defaults to today. |
| lag_days | integer | no | Shift metric_b this many days later before joining — 1 tests whether metric_a today predicts metric_b tomorrow (e.g. "does poor sleep tonight predict lower steps tomorrow?"). 0 (default) compares same |
Scan every (non-private) metric for what's changed lately: a recent period vs. the four-times-as-long period before it (period-over-period shift), any anomalies inside the recent period, and a trend over it.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| days | integer | no | Length of the "recent" window in days (default 7). The comparison baseline is the 4x-as-long period immediately before it, so a 7-day recent window compares against the preceding 28 days. |
Build an evidence bundle for "why did my <metric> look like that on <date>?": that day's value against a 90-day baseline, whether it qualifies as an anomaly, the trend leading into it, and any other metric that correlates with it strongly enough to be worth mentioning.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| metric | string | yes | One of steps, sleep_hours, resting_heart_rate, weight_kg, workout_minutes, mood, water_ml, heart_rate, hrv_ms. |
| date | string | yes | The day to explain, formatted YYYY-MM-DD. |

- Every tool, no call limit
- No card, and mcprush charges nothing for it
- Source published under MIT
- Runs on your machine — nothing of it reaches our gateway
- Nothing to cap, because mcprush bills nothing
What counts against your monthly calls
| Tool | Unit | Calls used | Out of the allowance |
|---|
Nothing here is billable: mcprush charges nothing to install Quantified Self or to call it, at any volume.
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
| Term | Level | What it prices | Points |
|---|---|---|---|
| capability-exposure | minimal | capability blast radius (minimal) — client exposure if the model is manipulated | −0 |
| verification-discount | source | publisher verification (provenance) — cryptographic build provenance ties the artifact to its source | −0 |
| coverage-honesty | source | inspection depth (source) — how much of the target the scan could see | −0 |
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.
Tools were statically extracted from the published source (20 recovered), not enumerated from a running server. Tool-poisoning, Unicode-smuggling, capability and toxic-flow analysis ran on this inferred surface, but a mis-parsed registration could be missed or mis-attributed, so tool-derived findings are capped below “confirmed”. To grade the real runtime surface, scan the running server: --command "npx -y <package>".
Capability — what it could do if the model were manipulated
Tags derived from each tool’s schema and the implementation, not from what the tool calls itself. minimal is the level these add up to.
| Tool | Capability tags | Why the tag was assigned |
|---|---|---|
| get_metric_history | no tags | |
| get_baseline | no tags | |
| detect_metric_anomalies | no tags | |
| calculate_metric_trend | no tags | |
| compare_metric_periods | no tags | |
| find_metric_correlation | no tags | |

Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.
The public result for this release does not print the flow graph, so there is nothing to show here. That is not the same as "no paths were found": what the scan did read is above, under coverage.
Supply chain and provenance
This is the first scan of this surface here, so there is nothing yet to compare it against.
Every result on this tab comes from one deterministic pass over the published package — offline, rule by rule, and auditable line by line above. Same methodology version, same bytes, same score.
Release history
Always latest — the install command names no version, so it installs the newest release when it runs; the current release on file is 0.8.1. Pin a release below and the command asks for exactly that one.
No release note was published with this version.
- The version this listing was on when mcprush began following its releases. The registry was not asked when it shipped, so this row carries no date.
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Any signed-in account that does not publish Quantified Self can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
