## 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 2026-08-20.

- **Endpoint Security**: 57/100
  - 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.
  - 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**: 67/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 687 tokens (~171/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 33/100
  - Stability observed for 10 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.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-08-19 (score 63, +1)

No change was recorded against any check on this day. Stability & Change Management went from 27 to 30. That category is still filling its 30-day observation window: 8 days of observed history at the previous scan, 9 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-08-17 (score 62, 0)

- [security] Tool “store_code” rewrote its description, which is the text the model reads
- [functional regression] Schema quality: 150 → 171

### 2026-08-16 (score 62, +1)

No change was recorded against any check on this day. Stability & Change Management went from 17 to 20. That category is still filling its 30-day observation window: 5 days of observed history at the previous scan, 6 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-08-14 (score 61, +1)

No change was recorded against any check on this day. Stability & Change Management went from 10 to 13. That category is still filling its 30-day observation window: 3 days of observed history at the previous scan, 4 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-08-12 (score 60, +1)

No change was recorded against any check on this day. Stability & Change Management went from 3 to 7.

### 2026-08-11 (score 59, +2)

- [functional] We updated how we score, so this day's move reflects our rubric, not a change to the server

### 2026-08-10 (score 57)

First indexed and scored.

## MCP tools (4)

### `store_code` (~185 tokens)

Store a sealed OAuth2 authorization code.

Called by the serverless callback function after the browser redirect. The
\``state`` carries BOTH the patron npub (the lookup/retrieve key) and the
operator npub (the PUBLIC key the code is sealed to) — see the SDK's
\``pack_oauth_state``. The code is sealed with NIP-44 to the operator so only
that operator's nsec can open it; the Neon row is keyed by the patron npub,
so retrieval (``retrieve_code(state=patron_npub)``) is unchanged.

Args:
    code: The authorization code from the OAuth provider.
    state: The packed state (``patron_npub.operator_npub``).

Returns:
    Dict with ``success`` key and a message.

Input parameters:

- `code` (string, required)
- `state` (string, required)

### `retrieve_code` (~106 tokens)

Retrieve a stored authorization code (one-time read, auto-deleted).

Called by the originating MCP server to pick up the code after the user
has authorized in the browser. Returns the encrypted code which the
caller decrypts using the same state token.

Args:
    state: The state token (patron npub) used during authorization.

Returns:
    Dict with ``code`` (encrypted) on success, or ``error`` if not found.

Input parameters:

- `state` (string, required)

### `collector_status` (~21 tokens)

Health check — shows the number of pending authorization codes and TTL.

### `service_status` (~172 tokens)

Report the running build so a redeploy can be verified. Free.

Delegates to the SDK's canonical ``build_service_status`` — the single
source of the service_status payload shape — so this collector reports the
same envelope as every other DPYC service. The load-bearing field is
\``build_info.fastmcp_cloud_git_commit_sha``: the commit Horizon actually
deployed. The post-merge deploy-verify probe reads it to confirm the live
service redeployed the merged sha; with no ``service_status`` tool to probe,
that sha reads as ``<none>`` and an otherwise-healthy deploy is flagged as
"did not land".

The vault/courier/operator fields are ``False``/empty by construction —
this is an unauthenticated community utility with no operator runtime.
