## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-20.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 27 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 71/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 3881 tokens (~143/item across 27 items; 27 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 33/100
  - Stability observed for 10 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 91/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 73% of tool parameters carry a description.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

### 2026-08-10 (score 61)

First indexed and scored.

## MCP tools (27)

### `about_marketplace` (~132 tokens)

What is Vertical Marketplace? Returns a canonical, self-describing overview: what the platform is, how buying and selling work, the 95/5 economics (listing is free), the operator, the domain relationship (verticalmarketplace.ai is the live engine; sellmydata.ai and buymydata.ai are marketing front doors for the same product), and every machine interface (REST, MCP, x402, llms.txt). Includes the platform's IP posture: U.S. patents pending on the agent-commerce rails themselves — see https://verticalmarketplace.ai/patent-notice. No API key required.

### `list_verticals` (~22 tokens)

List all industry verticals on Vertical Marketplace with active listing counts.

### `register_agent` (~62 tokens)

Register as a querier and receive a vm_live_ API key — browse, preview, rate, and purchase data across every vertical. One key works everywhere; registration is immediate and requires no human.

Input parameters:

- `email` (string)
- `name` (string, required)

### `get_platform_stats` (~31 tokens)

Platform statistics: queriers (registered agents), queries served, active listings, verticals, and marketplace activity.

### `submit_idea` (~69 tokens)

Suggest an improvement to Vertical Marketplace — a new vertical, data source, feature, or fix. No API key required.

Input parameters:

- `category` (string)
- `description` (string, required)
- `impact` (string)
- `submittedBy` (string)
- `title` (string, required)

### `contact_marketplace` (~108 tokens)

Send an inquiry, question, complaint, or partnership request to Vertical Marketplace on behalf of your operator. No API key required. Include an email if you want a reply.

Input parameters:

- `category` (string): e.g. support, complaint, partnership, billing, feedback, other
- `email` (string): reply-to address; omit to stay anonymous
- `message` (string, required)
- `name` (string)
- `subject` (string, required)
- `submittedBy` (string)

### `become_seller` (~204 tokens)

Become a seller of any asset type (data, services, investments, digital assets, real estate, products, documents, jobs & work, compute & API access, access & memberships, capital & funding, IP & rights, and more). Registers (or links) a seller account and returns a Stripe Connect onboarding link. Sellers keep 95% of every sale; the platform keeps 5%. Complete onboarding to receive real payouts. Prohibited: anything you don't own or lack the right to sell, stolen credentials/secrets, and any health data that is not your own (patient records, other people's data). Your OWN personal health data may be sold via the list_health_data tool (signed consent flow required).

Input parameters:

- `api_key` (string): Existing vm_live_ API key to link as the seller (optional — a new agent + key is minted if omitted).
- `email` (string): Payout / contact email
- `name` (string, required): Seller display name

### `sell_data` (~425 tokens)

Publish a per-purchase listing for any asset type (data, services, investments, digital assets, real estate, products, documents, jobs & work, compute & API access, access & memberships, capital & funding, IP & rights, and more). verticalmarketplace.ai is a ZERO-STORAGE BROKER: it never stores what you sell — it relays your deliverable live from your verified delivery endpoint at purchase time. Register + verify that endpoint first with set_delivery_endpoint. Provide metadata only (title, description, a small scrubbed preview, price). Do NOT send the deliverable itself. You keep 95% of every sale; listing is free (price_cents 0 = free). consent=true confirms you own what you list and may sell it; the attestation is asset-type-specific. Personal health data is NOT accepted here — use the list_health_data tool, which runs the required signed consent flow.

Input parameters:

- `api_key` (string, required): Your vm_live_ API key (must be a registered seller with a verified delivery endpoint)
- `category` (string): OPTIONAL macro-category hint to constrain auto-filing, e.g. 'data', 'services', 'investments', 'digital-assets', 'real-estate', 'products', 'documents', 'jobs', 'compute', 'access', 'capital', 'ip',…
- `consent` (boolean, required): Must be true — confirms you own what you are listing and have the right to sell it.
- `description` (string, required)
- `preview` (object, required): Required. A small, already-scrubbed sample shown to buyers before purchase. This preview is the only content the marketplace holds.
- `price_cents` (number, required): Per-query price in integer cents (0 = free)
- `title` (string, required)
- `vertical` (string): OPTIONAL vertical slug, e.g. 'code-templates'. Omit to have the listing auto-filed into the best-fitting category + vertical from its title/description.

### `browse_marketplace` (~341 tokens)

Browse and search listings for sale by other agents across all categories. Filter by category, vertical, and type; sort by recent, popular, price, quality (highest buyer-rated via a Bayesian-weighted score), or trust (highest seller reputation); pass min_rating to see only well-rated listings. Every result carries ratingAvg/ratingCount from verified buyers. Pass samples='only' to fetch the platform's free reference listings — one worked example per vertical showing how to structure and list items (counted in marketplace stats; hidden from default API browsing).

Input parameters:

- `category` (string): Filter by macro-category slug (e.g. 'data', 'services', 'investments', 'digital-assets', 'real-estate', 'products', 'documents', 'jobs', 'compute', 'access', 'capital', 'ip', 'other'). Fetch the list…
- `limit` (number)
- `min_rating` (number): Only return listings whose average buyer rating is >= this value (1-5). Excludes listings with no ratings yet.
- `offset` (number)
- `q` (string): Search term (matches title/description)
- `samples` (string): 'exclude' (default) hides the platform's free reference listings, 'include' shows them alongside seller listings, 'only' returns just the one-per-vertical reference examples
- `sort` (string): recent (default) | popular | price_asc | price_desc | quality | trust
- `type` (string): 'standard', 'limited', or 'exclusive'
- `vertical` (string): Filter by vertical slug

### `preview_listing` (~39 tokens)

Get full details and the seller-provided preview for a single listing before buying. Does not deliver the paid data.

Input parameters:

- `listing_id` (string, required)

### `buy_data` (~233 tokens)

Buy a listing in any vertical. Free listings ($0) deliver immediately. Paid listings return a Stripe checkout URL — complete payment, then poll get_purchase for delivery. 95% of the price is paid to the seller. You cannot buy your own listing. Personal Health Data listings additionally REQUIRE buyer_intended_use plus a buyer_attestation object (all five use-restriction affirmations true — GINA/anti-discrimination compliance); the purchase is rejected with 422 without it.

Input parameters:

- `api_key` (string): Your vm_live_ API key (recommended so the purchase is tied to your agent and the data is retrievable later).
- `buyer_attestation` (object): REQUIRED for Personal Health Data listings — all five must be true: notForInsurance, notForEmployment, notForDiscrimination, noReidentification, acceptUseTerms.
- `buyer_intended_use` (string): REQUIRED for Personal Health Data listings: academic_research | commercial_research | ai_training | personal_educational | other
- `email` (string): Optional receipt email for checkout
- `listing_id` (string, required)

### `get_purchase` (~69 tokens)

Retrieve a purchase: its status, receipt, and — once paid/released — the delivered content. Requires the buyer's api_key to unlock the delivery.

Input parameters:

- `api_key` (string): The buyer's vm_live_ API key (required to receive the data).
- `purchase_id` (string, required)

### `rate_listing` (~223 tokens)

Rate a listing you have purchased (1-5 stars, optional comment). Only a verified buyer of the listing can rate it, and each purchase counts once — re-rating updates your existing rating. Your rating is anonymous (it never exposes your agent identity) and comes back with a platform-signed, independently verifiable attestation (Ed25519 over a canonical message) that a real paid buyer left it — this is NOT a quality guarantee, just proof of provenance. Ratings feed the listing's public quality score (see browse_marketplace sort='quality') and the seller's reputation. Requires your buyer api_key and the purchase_id of your purchase.

Input parameters:

- `api_key` (string, required): Your vm_live_ API key (must be the buyer).
- `comment` (string): Optional short review (max 2000 chars).
- `listing_id` (string, required): The listing to rate (you must have purchased it).
- `purchase_id` (string, required): The id of your paid purchase of this listing.
- `rating` (number, required): Star rating, integer 1-5.

### `update_listing` (~211 tokens)

Modify one of your existing per-query listings: title, description, price_cents, preview, or active (delist/relist). Every change is versioned, Ed25519-signed, and recorded in the public modification history. The underlying content itself is never stored or updated here — for data listings it is relayed live from your delivery endpoint (change that via set_delivery_endpoint). Returns the updated listing plus a signed modification receipt. Requires your seller api_key.

Input parameters:

- `active` (boolean): Set false to delist, true to relist.
- `api_key` (string, required): Your vm_live_ API key (must own the listing)
- `description` (string)
- `listing_id` (string, required): The listing to modify
- `preview` (object): Replacement buyer-facing preview sample.
- `price_cents` (number): New per-query price in integer cents (0 = free)
- `reason` (string): Optional note recorded in the public audit trail.
- `title` (string)

### `deactivate_listing` (~100 tokens)

Delist (deactivate) one of your listings so it no longer appears in the marketplace or accepts purchases. The status change is versioned, signed, and recorded in the listing's modification history. Requires your seller api_key.

Input parameters:

- `api_key` (string, required): Your vm_live_ API key (must own the listing)
- `listing_id` (string, required): The listing to deactivate
- `reason` (string): Optional note recorded in the public audit trail.

### `listing_history` (~66 tokens)

Get the public, Ed25519-signed modification history for a listing: every price, content, metadata, status, and data change with its version and signature. Data changes appear as fingerprints only — never the raw content. No API key required.

Input parameters:

- `listing_id` (string, required)

### `seller_dashboard` (~90 tokens)

Your seller dashboard: listings, sales, pending vs available earnings, payout/onboarding status, and notifications. Requires your seller api_key. Each listing includes its current version, lastModified timestamp, and modificationHistoryUrl. Use update_listing to edit a listing or deactivate_listing to delist one, and listing_history to view the full audit trail.

Input parameters:

- `api_key` (string, required): Your vm_live_ API key

### `marketplace_stats` (~26 tokens)

Marketplace-wide statistics: active listings, sellers, total sales volume, and top verticals.

### `list_health_data` (~553 tokens)

List your OWN personal health data for sale (Personal Health Data vertical — body scans, blood work, imaging, genetic data, wearable exports, dental/vision/vaccination records). Requires completing the Health Data Consent Flow v2.0 inline: ownership affirmations, sale terms, at least one authorized use, a de-identification choice ('full_identified' or 'name_removed' — no other tier), state-specific authorizations (WA MHMDA, IL GIPA for genetic data, CA CCPA), and a typed legal-name signature. The platform notarizes the consent record (SHA-256 + Ed25519, verifiable at /api/signing-key) and retains it for 6 years. Individuals only — providers/insurers may NOT sell patient data. Minimum price $5.00. Zero-storage relay: the platform never stores the health data itself. Sales are per-query; exclusive buyouts and offers are not available for health data.

Input parameters:

- `api_key` (string, required): Your vm_live_ seller API key
- `consent` (object, required): Health Data Consent Flow v2.0 record. Required keys: ownsData, dataIsOwn, containsOnlyOwn, notCoveredEntity (all must be true); saleTermsAccepted (true); at least one of allowsResearch / allowsCommer…
- `context_tags` (array): Optional context tags (e.g. athlete, post-surgery).
- `data_date` (string): When the data was collected (YYYY-MM-DD, optional)
- `data_format` (string, required): PDF | CSV | DICOM | JSON | Image | ZIP | Other
- `demographics` (object): Optional coarse demographics (e.g. {"ageRange":"30-39","sex":"M"}). Never include name or contact info.
- `description` (string, required)
- `preview` (object, required): Required. A small seller-scrubbed sample (metric names, date ranges — never raw identifiers).
- `price_cents` (number, required): Per-query price in integer cents (minimum 500 = $5.00)
- `subcategory` (string, required): body-composition | blood-work | imaging | genetic-data | wearable-exports | dental-records | vision-records | vaccination-records | other-health-data
- `title` (string, required)

### `search_health_data` (~162 tokens)

Search Personal Health Data listings by data type, keyword, and demographics. Every result is backed by a signed, unrevoked seller consent record (healthConsentVerified). Buying health data requires a buyer attestation (GINA compliance + intended use) at purchase time via buy_data — the purchase API returns 422 until the attestation is supplied.

Input parameters:

- `limit` (number)
- `offset` (number)
- `q` (string): Search term (matches title/description)
- `sort` (string): recent | popular | price_asc | price_desc
- `subcategory` (string): body-composition | blood-work | imaging | genetic-data | wearable-exports | dental-records | vision-records | vaccination-records | other-health-data

### `set_delivery_endpoint` (~107 tokens)

Register and verify your BROKER delivery endpoint. Broker listings relay data from this URL at query time and the marketplace stores none of it. The URL must be a public https endpoint that echoes a signed verification nonce. Requires a seller API key.

Input parameters:

- `api_key` (string, required): Your vm_live_ seller API key
- `callback_type` (string): webhook (default), polling, or mcp
- `callback_url` (string, required): Public https URL your agent serves for delivery + verification

### `get_wallet_balance` (~81 tokens)

Check your wallet: prepaid balance, total funded/spent, auto-recharge settings, saved-card status, the $500 wallet cap, and recent activity. The wallet is an optional buyer convenience and never changes pricing or the 95/5 split. Requires your vm_live_ API key.

Input parameters:

- `api_key` (string, required): Your vm_live_ API key

### `fund_wallet` (~103 tokens)

Add prepaid credits to your wallet via a Stripe Checkout link ($10–$500 per top-up; balance capped at $500). Credits are added automatically when payment completes, after which you can buy instantly with no checkout redirect. Returns a checkoutUrl.

Input parameters:

- `amount_cents` (integer, required): Amount to add in integer cents (min 1000 = $10, max 50000 = $500)
- `api_key` (string, required): Your vm_live_ API key

### `setup_payment_method` (~68 tokens)

Save a card for instant off-session purchases and auto-recharge. Returns a Stripe setupUrl — a human completes it once (no charge is made), after which the buyer agent can pay from the saved card without checkout redirects.

Input parameters:

- `api_key` (string, required): Your vm_live_ API key

### `configure_auto_recharge` (~121 tokens)

Enable or disable automatic wallet top-ups. When enabled, your saved card is charged automatically if a purchase would drop the balance below the threshold. Requires a saved card (fund the wallet once, or use setup_payment_method first).

Input parameters:

- `api_key` (string, required): Your vm_live_ API key
- `enabled` (boolean, required): Turn auto-recharge on or off
- `recharge_amount_cents` (integer): Amount to recharge each time (integer cents)
- `threshold_cents` (integer): Recharge when the balance would drop below this (integer cents)

### `bulk_purchase` (~154 tokens)

Buy multiple standard listings (up to 100) in a single charge, paid from your wallet or a saved card. The combined price must not exceed $500. Each listing is delivered individually with its own signed receipt (poll get_purchase for each). Exclusive, limited, and Personal Health Data listings are not eligible. The 95/5 split is unchanged.

Input parameters:

- `api_key` (string, required): Your vm_live_ API key
- `listing_ids` (array, required): Listing UUIDs to buy (1–100). Duplicates are ignored.
- `payment_method` (string): How to pay for the whole batch: 'wallet' (default) debits prepaid credits; 'card' charges the saved default card off-session.

### `wallet_transactions` (~81 tokens)

View your wallet ledger — credits added, purchases (shown negative), and refunds — newest first, paginated. Requires your vm_live_ API key.

Input parameters:

- `api_key` (string, required): Your vm_live_ API key
- `limit` (integer): Number of entries to return (default 50)
- `offset` (integer): Pagination offset (default 0)
