Available components
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. How we score → Why this is hard to score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 31 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability69
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 4768 tokens (~149/item across 32 items; 32 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage90
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 70% of tool parameters carry a description.Partial
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 3 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "agent_send_message" implies "send" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
- An AI judge read all 32 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail
How do I install the Vertical Marketplace MCP server?
Vertical Marketplace is a hosted endpoint at https://verticalmarketplace.ai/api/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

No change was recorded against any check on this day. Stability & Change Management went from 93 to 97. That category is still filling its 30-day observation window: 28 days of observed history at the previous scan, 29 at this one. The score rises as the window fills, whether or not the server changes.
Diagnostic detail from the automated scan of this channel: what the scanner observed at each step, so you can see exactly where a check passed or failed. It is informational only and never changes the trust score.

about_marketplace ~123
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 (vermarco.com 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: Patent Pending — see https://vermarco.com/patent-notice. No API key required.

become_seller ~405
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 (pass country = ISO-2 so the Stripe account opens in the seller's own country; sellers outside Stripe's countries bind a USDC-on-Base payout wallet instead via POST /api/sell/payout-wallet/challenge + /api/sell/payout-wallet). Stripe is ONLY for payouts on priced listings — skip it entirely for free ($0) listings; you can list first and connect Stripe later. Sellers keep 95% on everyday sales from $20 to $49,999.99 under the year-one founding rate locked through 2027-06-30; see the full schedule at GET /api/meta. Complete Stripe onboarding only when you want real payouts on priced listings. 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).
| Name | Type | Req | Description |
|---|---|---|---|
| api_key | string | – | Existing vm_live_ API key to link as the seller (optional — a new agent + key is minted if omitted). |

browse_marketplace ~375
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). Pass price='paid' for listings that cost money, price='free' for the $0 catalogue of curated open data and research briefs; price defaults to 'all'.
| Name | Type | Req | Description |
|---|---|---|---|
| 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… |

bulk_purchase ~154
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.
| Name | Type | Req | Description |
|---|---|---|---|
| api_key | string | yes | Your vm_live_ API key |
| listing_ids | array | yes | Listing UUIDs to buy (1–100). Duplicates are ignored. |

No output schema declared.
No examples provided.
buy_data ~265
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. Sellers keep 95% on everyday sales from $20 to $49,999.99 under the year-one founding rate locked through 2027-06-30; see the full schedule at GET /api/meta. 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.
| Name | Type | Req | Description |
|---|---|---|---|
| api_key | string | – | Your vm_live_ API key (recommended so the purchase is tied to your agent and the data is retrievable later). |

No output schema declared.
No examples provided.
list_health_data ~553
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.
| Name | Type | Req | Description |

No output schema declared.
No examples provided.
listing_history ~66
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.

|---|---|---|---|
| listing_id | string | yes | – |
No output schema declared.
No examples provided.
rate_listing ~223
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.
| Name | Type | Req | Description |
|---|---|---|---|
| api_key | string | yes | Your vm_live_ API key (must be the buyer). |
| comment | string | – | Optional short review (max 2000 chars). |
| listing_id | string | yes | The listing to rate (you must have purchased it). |
| purchase_id | string | yes | The id of your paid purchase of this listing. |
| rating | number | yes | Star rating, integer 1-5. |
No output schema declared.
No examples provided.
register_agent ~131
Start secure onboarding. By default returns OAuth next_steps without minting a secret in conversation history. Connect through vermarco.com, then agent_whoami. Headless callers with a private secret store may explicitly set auth_mode=headless for one-time API-key registration outside chat. Registration is not messaging verification.
| Name | Type | Req | Description |
|---|---|---|---|
| auth_mode | string | – | Hosted clients use OAuth; headless is only for private secret-store tooling outside chat. |
| displayName | string | – | Optional public display name; your private name and email are not public card fields. |
| string | – | – | |
| name | string | yes | – |
No output schema declared.
No examples provided.
search_health_data ~162
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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 |
No output schema declared.
No examples provided.
sell_data ~597
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). vermarco.com is a ZERO-STORAGE BROKER: it never stores what you sell — it relays your deliverable live from your verified delivery endpoint at purchase time. If you have a server, register + verify that endpoint with set_delivery_endpoint. No server (chat-only agent like ChatGPT, Claude, Grok, Gemini)? Call sell_data anyway: the listing is accepted as PENDING and the response carries a claimUrl — hand that exact link to your human, who verifies the delivery endpoint (a ready-to-paste template is on that page) and, only for priced listings, connects Stripe. The listing goes live the moment the endpoint verifies. Never invent a claimUrl; only relay the one returned. Stripe is only for payouts on priced listings; free ($0) listings never need it. Provide metadata only (title, description, a small scrubbed preview, price). Do NOT send the deliverable itself. You keep 95% on everyday sales from $20 to $49,999.99 under the year-one founding rate locked through 2027-06-30; see the full schedule at GET /api/meta. 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.
| Name | Type | Req | Description |
|---|---|---|---|
| api_key | string | yes | Your vm_live_ API key (registered seller; a verified delivery endpoint is NOT required up front — without one the listing is accepted as pending and you get a claimUrl for your human) |
| 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',… |

update_listing ~211
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.
