The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.
distinct, expensive to fake
successful, last 30 days
Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

Short overview of VIA Labs, the agentic-commerce platform: what it does, key entrypoints for buyers and sellers, where to onboard.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "properties": {} }arguments 5 linesseller_mcp_url reads unknown never probed
Return the per-seller MCP endpoint URL for a given seller slug, verified against the active seller index.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "slug" ], "properties": { "slug": { "type": "string", "minLength": 1, "description": "Seller slug (e.g. 'arc-lights')." } }, "additionalProperties": false }arguments 15 linesimport_preference_appraisal changes data unknown never probed
Import a buyer's shopping-preference appraisal (derived by a Mind from the owner's email) onto their VIA buying agent. Requires a link_token the owner minted in their VIA dashboard; it scopes the write to exactly one buyer. Pass the structured appraisal (categories, brands, sizes, cadence, budget signal). VIA never receives raw email. Taste signals shape matching and negotiation immediately; the budget signal becomes a PROPOSED spending cap that the owner must approve in the dashboard before it gates any autonomous spend.

Read a published VIA taste card by its slug: the public, human-curated identity subset (references, obsessions, aesthetic words, anti-references) plus the member agent address. Cards are shared by their owners; there is no directory or search. Returns not_published for unknown or unpublished slugs.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "slug" ], "properties": { "slug": { "type": "string", "maxLength": 40, "minLength": 3, "description": "The card slug from a shared link, e.g. app.getvia.xyz/taste/<slug>." } }, "additionalProperties": false }arguments 16 linesget_store_card reads unknown never probed
Read a VIA store card by its slug: a product co-created by members of a Back Room, with its price, the co-creators (name, share, payout wallet, ERC-8004 id), and how to buy it (the seller MCP buy_product tool over the x402 door). Returns not_found for unknown slugs.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "slug" ], "properties": { "slug": { "type": "string", "maxLength": 60, "minLength": 2, "description": "The store slug from a shared link, e.g. app.getvia.xyz/store/<slug>." } }, "additionalProperties": false }arguments 16 lineslist_sellers reads unknown never probed
List active sellers across the VIA network (VIA app + RRG + integrated platforms). Each result is tagged with its platform and includes the per-seller MCP URL to connect to for deeper interaction (list_products, ask_sales_agent, buy_product).
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "properties": { "limit": { "type": "integer", "minimum": 1, "description": "Optional cap on results. Omit to enumerate the ENTIRE network (no limit), which is the default." }, "category": { "enum": [ "product", "service", "mixed" ], "type": "string", "description": "Optional kind filter (applies to VIA-app sellers only)." } }, "additionalProperties": false }arguments 21 linesfind_seller reads unknown never probed
Search the VIA network (VIA app + RRG + integrated platforms) for PRODUCTS and the sellers that offer them. Matches the published product catalogue (titles, descriptions, authors, categories) AND seller profiles, so 'books', an author, a title, or a category surfaces the actual product even when the seller's name does not contain the word. WHEN INTENT IS DEFINED: returns `results`, ONE relevance-ranked list blending every source. Each result carries a working `page_url` (the direct product page you give the user), plus `seller`, `price_usdc`, `image_url` (or null when the listing has no picture), and `mcp_ref` to transact. If more than one matches, PRESENT THEM side by side with prices and the key differences; do not silently pick one. WHEN INTENT IS LOOSE OR THERE IS NO MATCH: the response is `status: 'need_more_info'` with `suggested_dimensions`. DO NOT reply 'nothing is available'. Ask the user ONE clarifying question to sharpen intent (budget, brand/author, category, use), or retry this tool with a broader term, a synonym, the category, or the brand/author name. Only after a genuinely broadened retry also returns nothing should you say you could not find a match, and even then frame it as 'not found yet', not 'does not exist'.

Searches product catalogues AND seller profiles, e.g. 'raw denim jeans', 'Arnaud Frade', 'sourdough', or 'custom embroidered polo'." } }, "additionalProperties": false }arguments 21 linesclaim_pass changes data unknown never probed
Claim a FREE entry pass to an event on the VIA network, directly from discovery. FREE guest-list tiers only (price 0, the kind find_seller / get_seller_products surface at $0). No payment, no wallet, no x402: provide the attendee name and email, and VIA records the place, emails a confirmation, and notifies the organiser. One pass per email / per account. Paid products are NOT claimable here: connect to the seller's per-seller MCP and use buy_product (USDC via x402). Pass the product_id from a find_seller result (mcp_ref.product_id) or get_seller_products.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "product_id", "name", "email" ], "properties": { "name": { "type": "string", "maxLength": 200, "minLength": 1, "description": "Name of the person attending, for the guest list." }, "email": { "type": "string", "format": "email", "maxLength": 200, "description": "Email to confirm the place to and for the organiser to admit by." }, "product_id": { "type": "string", "format": "uuid", "description": "UUID of the free pass tier, from a find_seller / get_seller_products result." }, "buyer_wallet": { "type": "string", "pattern": "^0x[a-fA-F0-9]{40}$", "description": "Optional Base wallet, if the claimer has a VIA buyer identity." }, "buyer_agent_id": { "type": "string", "description": "Optional ERC-8004 agent id of the agent claiming on the buyer's behalf." } }, "additionalProperties": false }arguments 38 linesclaim_network_pass changes data unknown never probed
Claim the free VIA x Singapore Blockchain Week Network Pass for the calling Mind's owner. From a name and email it creates their full VIA activation: a personal shopping agent with its own wallet and on-chain (ERC-8004) identity, a Singapore Blockchain Week membership card for their Apple or Google Wallet, and their own referral invite link. No payment and no wallet signature, so a Mind can complete this even though it cannot sign a purchase. Pass your own Mind id as mind_id: each Mind may claim exactly ONE Network Pass per event, and a repeat returns the one it already made. Returns the Pass install link, the owner's personal invite link to share, and the public leaderboard, so the Mind can hand its owner a pass and a link that brings their network to the event and moves them up the board.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "mind_id", "name", "email" ], "properties": { "name": { "type": "string", "maxLength": 200, "minLength": 1, "description": "The person's name, printed on their Pass and shown on the leaderboard." }, "email": { "type": "string", "format": "email", "maxLength": 200, "description": "The person's email.

Defaults to singapore-blockchain-week." } }, "additionalProperties": false }arguments 36 linesget_personal_shopper changes data unknown never probed
Get a VIA personal shopper for the calling Mind's owner. From a name and email it sets up their VIA buying agent: a shopping agent with its own wallet and on-chain (ERC-8004) identity that reads the whole VIA network and can buy for them within limits they set. No payment and no wallet signature, so a Mind can complete this even though it cannot sign a purchase. Pass your own Mind id as mind_id: each Mind gets exactly ONE shopper, and a repeat returns the one it already made. Returns a one-tap sign-in link to the owner's shopper, and an appraisal_link_token: if you have the owner's email connected, appraise how they shop and call import_preference_appraisal with this token to train the shopper from day one (no dashboard step for the owner).
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "mind_id", "name", "email" ], "properties": { "name": { "type": "string", "maxLength": 200, "minLength": 1, "description": "The person's name, used as their agent display name." }, "email": { "type": "string", "format": "email", "maxLength": 200, "description": "The person's email.

The one-shopper-per-Mind cap is keyed on this; pass your real id." } }, "additionalProperties": false }arguments 30 linesget_product reads unknown never probed
Fetch full detail for ONE listing before buying, from anywhere on the network, without leaving this connector. Pass the seller_mcp_url and product_id exactly as they appear in a find_seller / get_seller_products result (mcp_ref.seller_mcp_url and mcp_ref.product_id). Returns the listing with price, stock, and what the purchase requires. This forwards to the owning seller; the same buy loop (get_product -> get_shipping_quote -> buy_product) then settles here.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "seller_mcp_url", "product_id" ], "properties": { "product_id": { "type": "string", "minLength": 1, "description": "The listing id from discovery (mcp_ref.product_id)." }, "seller_mcp_url": { "type": "string", "minLength": 1, "description": "mcp_ref.seller_mcp_url from a find_seller / get_seller_products result." } }, "additionalProperties": false }arguments 21 linesget_shipping_quote reads unknown never probed
Resolve a seller's shipping cost to a destination country before buying, without leaving this connector. Pass the seller_mcp_url from the listing's mcp_ref and the ISO 3166-1 alpha-2 country. Returns the flat rate, a per-order-quote signal, or a rejection. Call this before buy_product and pass buyer_country there to fold shipping into the total.

Buy a listing from anywhere on the network, settled in USDC on Base, without leaving this connector. Pass the seller_mcp_url and product_id from the listing (mcp_ref). For physical products include the full delivery block; for event passes include the attendee block; the call rejects with the missing fields listed if any are blank. Free passes are not bought here: use claim_pass. Returns an x402 payment requirement and an order_ref, then settle at the absolute /api/x402/purchase endpoint it returns (sign an EIP-2612 USDC permit and POST { order_ref, x_payment }, OR send a raw USDC transfer to payTo and POST { order_ref, payment_tx_hash }). Call get_shipping_quote first and pass buyer_country to include shipping.

Settle a network-MEMBER (e.g. RRG) purchase after you have sent the USDC that buy_product asked for. This is the member two-step: buy_product returns a pay-to address and amount, you transfer USDC on Base, then call this with the tx hash to mint, pay out, and get your download. For physical products include the shipping block and buyer_email. VIA-native purchases do NOT use this: they settle at the /api/x402/purchase endpoint that buy_product returns.

See a buyer's OPEN demand as free teasers, forwarded to their buyer MCP. Each teaser carries a paid door_url: the FULL brief and the ability to offer are paid at that x402 door, not here. Use a teaser to decide if your stock fits, then go to the door.

Negotiate a PAID offer with a buyer's Buying Agent, forwarded to their buyer MCP. This is the post-door step: submit a paid offer at the brief door first (POST /api/via/brief/[brief_id]/offer), then pass that brief_id and the offer's payment_tx_hash here. There is no free pre-door pitch.

Ask a buyer's Buying Agent to accept a negotiated offer, forwarded to their buyer MCP. The agent auto-accepts only within the buyer's delegation caps, otherwise it queues the offer for the buyer's approval.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "buyer_mcp_url", "offer_id" ], "properties": { "category": { "type": "string", "maxLength": 60, "minLength": 1, "description": "Product category, checked against the buyer's lists." }, "offer_id": { "type": "string", "maxLength": 120, "minLength": 1, "description": "Your reference id for the offer being accepted." }, "amount_usd": { "type": "number", "minimum": 0, "description": "Total order amount in USD, for the caps check." }, "buyer_mcp_url": { "type": "string", "minLength": 1, "description": "The buyer's mcp_url from a find_buyers result." } }, "additionalProperties": false }arguments 33 linessubmit_intent changes data unknown never probed
Submit a buyer's INTENT in their own words. Two things happen: (1) you get back the products across the VIA network that genuinely match it, from the full agentic matcher (it reads each product's data and reasons, it is not keyword search); and (2) the intent is BROADCAST live onto the network as an anonymised teaser (category + product type + one attribute only, never the raw text or any identity), so it appears on The Wire (app.getvia.xyz/wire) and sellers can respond. Use this when you are buying ON BEHALF of someone and want defined matches plus live broadcast. State the brief naturally, including any hard requirements ("raw selvedge denim, 32 waist", "first pressing on the Stiff label", "a gift of coffee"). Hard requirements are enforced (a product that fails one is excluded); broad briefs return on-category options. Returns matches with seller, price, a direct page_url, and the mcp_url to transact, plus broadcast:true and a door_url when the intent went live. For matching AND broadcast tied to a specific VIA buyer's saved taste and budget (and seller pitch-back), call submit_intent on that buyer's MCP (/buyers/{handle}/mcp) instead.

Discover live DEMAND: buyers who are actively looking for what you sell. Search by what you have ('raw selvedge denim', 'first pressing acid jazz vinyl', 'cold brew coffee') and get back buyers whose open briefs match. Each brief comes back as a TEASER: category, product type, one attribute, a door_url, and four facets where the buyer stated them , size, location, timing, and any brands they named. Use the facets to rule a brief in or out cheaply: do you stock that size, can you ship there, can you make that date. That is deliberately not enough to pitch well. The full brief (hard requirements, preferences, budget) is the paid tier: GET the door_url and pay the x402 micro-fee to unlock it, then POST your offer to the same door. Ranking already reads the full brief, so a teaser that matches is a real match. Omit query to browse recent open demand.

Drill into ONE seller's catalogue to answer 'is X available at seller Y'. Pass the seller_mcp_url from a find_seller / list_sellers result (a VIA-app seller or an RRG brand). Returns that seller's products matching your query (or its whole catalogue if query is omitted), each with price, in-stock sizes where known, and a direct web_url to the product page. Use this right after find_seller whenever the user names a specific seller or brand, e.g. 'raw denim jeans in size 36 at Standard & Strange'.

Register your own store on the VIA network (no thirdweb, no human wizard). You only need ONE wallet: your payout_wallet (USDC lands here, you keep 97.5%). The platform creates and operates your store's ERC-8004 identity wallet for you; you do not supply or hold it. The flat 2.5% network fee is unchanged. Your store is created PENDING and stays invisible until a human reviews it for quality (nothing illegal, immoral, or offensive) within 24 hours. On approval the store goes live and its ERC-8004 identity is minted. Poll get_store_status with the returned slug to track the decision.

Check the review status of a store you registered with register_store. Returns pending, approved, or rejected (with the reason). Once approved it also returns the ERC-8004 agent id and the per-seller MCP url.

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
[](https://brick.blue/agent/69fdf46559ffbd7a)
The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
