More than a lab transaction

## Order your labs. Build your baseline. Know what to do next.

Vitals Vault combines direct-access lab ordering with the interpretation layer that makes results useful after the blood draw. Essential starts at $99, Advanced is $199, and Max is $399—one-time purchases with no required subscription.

A digital dashboard and Functional Health Report

Past-lab uploads that bring supported historical results into one timeline

Standard and functional-range context for supported biomarkers

Trend views that help show what changed over time

Educational action guidance and PocketMD access

A persistent place to bring future results back into context

## Built for the moment of intent

### I have a concern

Use controlled educational inputs to compare Essential, Advanced, and Max—or exclude all three and optimize a custom panel under an exact budget against the complete checkout-eligible catalog.

### I know the test

Search the live public catalog, verify the exact handle, and return the current customer-safe price.

### I want to measure change

Find a baseline or targeted retest path, then use the included report and trend experience after results return.

The proof loop

## Act. Retest. Prove what changed.

1. Step 1

Order a panel or build a custom set of tests

2. Step 2

Establish a baseline from the completed results

3. Step 3

Use the report and educational guidance to choose practical next steps

4. Step 4

Retest when appropriate and compare the new result with the baseline

## One-minute quickstart

1. Add the product server URL to a ChatGPT/OpenAI, Claude, or other Streamable HTTP MCP client.
2. Confirm the client can initialize and list tools without authentication.
3. Start with: “I am 44, female, feeling tired, do not want a package, and have a hard budget of $150. Give me the best Vitals Vault custom panel.”

```
{
  "mcpServers": {
    "vitalsVault": {
      "url": "https://mcp.vitalsvault.com/mcp",
      "transport": "streamable-http"
    }
  }
}
```

Client setup screens change over time. Use the current custom-connector or remote-MCP flow in your runtime and provide only the canonical server URL above; Phase A uses no OAuth or API key.

The client should translate that request into controlled fields, call `recommend_panel` with `custom_only`, and return an exact within-budget set with current prices and a human checkout URL. It must not send the free-text symptom sentence to Vitals Vault or claim that it created a cart.

## Endpoints

- Product tools: `POST https://mcp.vitalsvault.com/mcp`

- Protocol revision: 2025-06-18
- Response formats: JSON and Server-Sent Events

## Capability boundary

The server reads public educational biomarker and currently orderable catalog information, compares published blood-testing services, and returns public pages as markdown. Its recommendation tool accepts only controlled concern, goal, broad age-band, sex-context, package-preference, and budget fields. It is anonymous, stateless, and read-only. It cannot diagnose, create a cart or order, create or access an account, read lab results, accept identity information, or take payment.

Educational information only. Vitals Vault does not diagnose, prescribe, or replace a licensed clinician, and urgent symptoms require prompt medical care rather than a lab-shopping flow.

### Input schema

```
{
  "type": "object",
  "properties": {
    "query": {
      "type": "string",

}
```

### Example arguments

```
{
  "query": "thyroid",
  "itemType": "all",
  "page": 1,
  "limit": 20
}
```

**Not for:** Do not infer that a provider/Junction identifier makes a row orderable; only returned public results are eligible.

**Authentication:** None for this anonymous public tool.

**Rate limit:** Shared public MCP limit: 100 requests per 15 minutes per client by default.

**Output and errors:** Returns customer-safe items plus one-based pagination metadata (total, hasMore, nextPage). Continue until hasMore is false to enumerate the same eligible public catalog the website exposes. Upstream failures become a stable server error without internal details.

**Data provenance:** Current Vitals Vault public checkout browse policy, including curation, environment, Galleri, applicability, price, pagination, and orderability decisions; projected to customer-safe fields.

**Privacy:** Read-only and customer-safe. No PHI, customer/session/account/order/payment data, credentials, provider secrets, raw logs, or internal/Junction identifiers are accepted or returned.

Get an orderable catalog item `get_lab_catalog_item`

Revalidates one exact public catalog handle for current price and orderability under the website checkout policy. It never fuzzy-substitutes and returns a safe not-found result for ineligible items.

### Input schema

```
{
  "type": "object",
  "properties": {
    "handle": {
      "type": "string",
      "minLength": 1,
      "maxLength": 128,
      "description": "Exact public catalog handle."
    }
  },
  "required": [

  ],
  "additionalProperties": false
}
```

### Example arguments

```
{
  "handle": "apolipoprotein-b"
}
```

**Not for:** Do not fuzzy substitute another item when an exact public handle is missing.

**Authentication:** None for this anonymous public tool.

**Rate limit:** Shared public MCP limit: 100 requests per 15 minutes per client by default.

**Output and errors:** Returns one exact customer-safe orderable item. A missing, ineligible, inactive, or non-public handle returns catalog_item_not_found; the tool never fuzzy-substitutes another test.

**Data provenance:** Current Vitals Vault public checkout exact-lookup and shared browse-eligibility policy; Junction identity alone is never treated as orderability.

**Privacy:** Read-only and customer-safe. No PHI, customer/session/account/order/payment data, credentials, provider secrets, raw logs, or internal/Junction identifiers are accepted or returned.

Recommend a Vitals Vault panel `recommend_panel`

Returns a controlled educational Essential, Advanced, Max, or exact-budget Build Your Own Panel starting point. A custom_only request with maxBudgetUsd excludes standard panels. Every selection is revalidated against the complete eligible catalog. Inputs exclude free-text symptoms, identity, private results, and PHI; the tool never diagnoses, stores a health record, or creates a cart.

}
```

**Not for:** Do not send names, dates of birth, medications, raw lab results, free-text symptoms, account identifiers, or a diagnosis request.

**Authentication:** None for this anonymous public tool.

**Rate limit:** Shared public MCP limit: 100 requests per 15 minutes per client by default.

**Output and errors:** For a standard panel, returns the recommended panel, transparent alternatives, rationale, and human builder link. For custom_only, returns the exact budget, validated total, remaining budget, customer-safe selected tests with educational reasons, limited omissions, catalog-completeness evidence, and a human Build Your Own Panel URL. It never claims that a cart or order exists. Urgent-symptom input suppresses shopping. Stable safety fallbacks return the clean human builder.

**Data provenance:** Standard panels use code-owned package facts. Custom-only recommendations intersect a controlled educational intent profile with every page of the website checkout-eligible catalog, optimize within the exact price ceiling, then exact-revalidate every selected handle immediately before handoff. The private consultation runtime is not called.

**Privacy:** Read-only and customer-safe. No PHI, customer/session/account/order/payment data, credentials, provider secrets, raw logs, or internal/Junction identifiers are accepted or returned.

Open the guided panel builder `start_guided_panel_builder`

Returns the canonical entry for the full human-controlled Vitals Vault consultation, with no health answers in the URL. It creates no session, cart, account, order, or payment.

**Authentication:** None for this anonymous public tool.

**Rate limit:** Shared public MCP limit: 100 requests per 15 minutes per client by default.

**Output and errors:** A successful call returns MCP text content plus structuredContent. Tool-level not-found or safety outcomes set isError when appropriate. Server failures use a stable JSON-RPC internal error without stack traces or upstream details.

**Data provenance:** Vitals Vault public code-owned product and documentation facts.

**Privacy:** Read-only and customer-safe. No PHI, customer/session/account/order/payment data, credentials, provider secrets, raw logs, or internal/Junction identifiers are accepted or returned.

Compare blood testing services `compare_blood_testing_services`

Returns a factual side-by-side comparison of Vitals Vault and a supported blood-testing service using public master-table facts and methodology. It excludes medical advice and unsupported superiority claims.
