_ used through this hub 30 days

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.

_ what it can do 4 tools
4 never probed 0 of 4 classified

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.

  • list_offers unknown never probed

    Use this first to compare Zinvyl's four fixed-scope offers. Returns each offer's price, delivery window, required inputs, exclusions, and direct intake URL; use get_acceptance_tests only after selecting an offer.

    mcp-tool

    {
  "type": "object",
  "$schema": "https://json-schema.org/draft/2020-12/schema",
  "properties": {}
}
    arguments 5 lines
  • qualify_task unknown never probed

    Use when a buyer's sanitized problem is not yet mapped to an offer. Returns one fixed offer ID, a broader-service route, or a scope-reduction decision; it performs no diagnosis and creates no order.

    mcp-tool

    {
  "type": "object",
  "$schema": "https://json-schema.org/draft/2020-12/schema",
  "required": [
    "summary"
  ],
  "properties": {
    "summary": {
      "type": "string",
      "maxLength": 3000,
      "minLength": 20,
      "description": "Sanitized expected-versus-actual outcome. Do not include credentials, tokens, personal data, or production secrets."
    }
  }
}
    arguments 15 lines
  • get_acceptance_tests unknown never probed

    Use after list_offers or qualify_task identifies an offer. Returns the exact delivery acceptance tests, exclusions, and evidence boundaries that limit what Zinvyl may claim for that offer.

    mcp-tool

    {
  "type": "object",
  "$schema": "https://json-schema.org/draft/2020-12/schema",
  "required": [
    "offer_id"
  ],
  "properties": {
    "offer_id": {
      "enum": [
        "zinvyl.freight.workflow-audit.v1",
        "zinvyl.api.workflow-failure-rescue.v1",
        "zinvyl.api.failure-triage.v1",
        "zinvyl.freight.full-workflow-audit.v1"
      ],
      "type": "string",
      "description": "Exact published offer ID returned by list_offers or qualify_task, including zinvyl.freight.workflow-audit.v1, zinvyl.freight.full-workflow-audit.v1, zinvyl.api.failure-triage.v1, and zinvyl.api.workflow-failure-rescue.v1."
    }
  }
}
    arguments 19 lines
  • prepare_purchase_route unknown never probed

    Use only after selecting an offer and confirming explicit purchasing authority. Returns the purchase-intent schema and payment-route API endpoint; it does not create, fund, verify, or start an order.

    mcp-tool

    {
  "type": "object",
  "$schema": "https://json-schema.org/draft/2020-12/schema",
  "required": [
    "offer_id",
    "human_authorized_to_fund"
  ],

      "enum": [

        "zinvyl.api.workflow-failure-rescue.v1",
        "zinvyl.api.failure-triage.v1",
        "zinvyl.freight.full-workflow-audit.v1"
      ],
      "type": "string",
      "description": "Exact published offer ID returned by list_offers or qualify_task, including zinvyl.freight.workflow-audit.v1, zinvyl.freight.full-workflow-audit.v1, zinvyl.api.failure-triage.v1, and zinvyl.api.workflow-failure-rescue.v1."
    },
    "human_authorized_to_fund": {
      "type": "boolean",
      "description": "True only when an authorized representative approved the request or an authorized purchasing agent is acting within explicit delegated authority for this offer, amount, and material limits."
    }
  }
}
    arguments 24 lines
_ try it over mcp through the hub, ceiling 0

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.

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.

_ how we knowoff the mcp door
card completeness
80%

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.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.

26 more sit on this domain. All of them.
