## 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 2026-09-27.

- **Endpoint Security**: 66/100
  - 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 4 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 is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 85/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 405 tokens (~101/item across 4 items; 4 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 20/100
  - Stability observed for 6 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

First indexed and scored.

## MCP tools (4)

### `list_offers` (~54 tokens)

List Zinvyl fixed-scope offers

Use this first to compare Zinvyl's six 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.

### `qualify_task` (~79 tokens)

Qualify a bounded task

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.

Input parameters:

- `summary` (string, required): Sanitized expected-versus-actual outcome. Do not include credentials, tokens, personal data, or production secrets.

### `get_acceptance_tests` (~115 tokens)

Get offer acceptance tests

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.

Input parameters:

- `offer_id` (string, required): 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.workf…

### `prepare_purchase_route` (~157 tokens)

Prepare an authorized funding route

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.

Input parameters:

- `human_authorized_to_fund` (boolean, required): 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.
- `offer_id` (string, required): 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.workf…
