## 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 2026-10-16.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - 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**: 70/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 476 tokens (~95/item across 5 items; 5 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 50/100
  - Stability observed for 15 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 6 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).

## MCP tools (5)

### `search_activities` (~107 tokens)

Search OiAir public activities using its current search API, ranking and filters. Age is inclusive; weekdays use Sunday=0 through Saturday=6, and any selected day may match. Age, day and time must match the same published group. Keep unresolved constraints and unknown availability; results do not confirm a place.

Input parameters:

- `cursor` (string)
- `filters` (object)
- `limit` (integer)
- `locale` (string)
- `query` (string)

Output parameters:

- `appliedFilters` (object)
- `bookingSemantics` (object)
- `items` (array)
- `nextCursor` (string|null)
- `queryStatus` (string)

### `get_organization` (~59 tokens)

Read the current public organization profile and its address-scoped published groups, prices and source timestamps. This exposes published facts only and does not provide staff, parent or participant data.

Input parameters:

- `locale` (string)
- `organizationId` (string, required)

Output parameters:

- `bookingSemantics` (object)
- `generation` (string)
- `item` (object)
- `revision` (integer)
- `syncedAt` (string)

### `list_offerings` (~67 tokens)

List all current published groups belonging to one public organization at its current address. Each group retains its exact publication ID, version, schedule, prices and confirmation timestamps; an empty list does not authorize substituting another group.

Input parameters:

- `locale` (string)
- `organizationId` (string, required)

Output parameters:

- `bookingSemantics` (object)
- `generation` (string)
- `items` (array)
- `organizationId` (string)
- `revision` (integer)
- `syncedAt` (string)

### `get_offering` (~75 tokens)

Read one exact, current published group by publication ID. Optionally require its expected version. Withdrawn, expired, changed-address or stale-version groups fail rather than falling back to another group. Published availability remains unknown.

Input parameters:

- `expectedVersion` (integer)
- `locale` (string)
- `publicationId` (string, required)

Output parameters:

- `bookingSemantics` (object)
- `generation` (string)
- `item` (object)
- `revision` (integer)
- `syncedAt` (string)

### `get_booking_link` (~95 tokens)

Prepare a canonical PT-BR OiAir form link for one exact organization, publication and expected version. Trial requires that the selected group offers a trial. Opening the link and submitting a request are separate actions; this tool neither submits a request nor reserves or confirms a place.

Input parameters:

- `expectedVersion` (integer, required)
- `organizationId` (string, required)
- `publicationId` (string, required)
- `visit` (string)

Output parameters:

- `bookingSemantics` (object)
- `checkedAt` (string)
- `offeringId` (string)
- `organizationId` (string)
- `publicationId` (string)
- `source` (string)
- `url` (string)
- `validUntil` (string)
- `version` (integer)
- `visit` (string)
