## 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 2026-11-05.

- **Endpoint Security**: 63/100
  - 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 17 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 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**: 64/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 1455 tokens (~85/item across 17 items; 17 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 13/100
  - Stability observed for 4 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 72/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 17% 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 17 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 18 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (17)

### `about_onlyfins` (~46 tokens)

About OnlyFins

Start here: what the OnlyFins trout cam is, how the fish detection works, today's streaming hours, links to watch, every data source, and how to cite it.

### `trout_facts` (~84 tokens)

Trout facts

Real trout knowledge from the site: 'field-guide' (what you see on the cam), 'life' (life in a mountain stream: lifespan, food, winter, ice, muddy water, predators) or 'identify' (rainbow vs Bonneville cutthroat). Or search with q.

Input parameters:

- `q` (string)
- `topic` (string)

### `pool_roster` (~69 tokens)

The fish of the pool

Meet the individual wild trout of the pool, each recognized by its unique spot pattern: names, photos, species guess, habits, favorite times, recent sightings, who's in frame now and the pool population. Pass a fish's slug for one profile with its sightings.

Input parameters:

- `fish` (string)

### `whos_that_trout` (~184 tokens)

Who's That Trout? (live game)

A live identification game for vision-capable agents (people play too). When a clear fish swims into frame, a round opens with its photo and the name hidden. Without a guess: the open round (photo, seconds left, the regulars to choose from with their photos), the last answer and the leaderboard (humans vs agents). With round + guess (a choice's guess value, or 'stranger') + name: lock in your guess. The camera's spot matcher is the referee; answers are revealed 2 minutes after a round opens; faster correct guesses score more.

Input parameters:

- `guess` (string)
- `name` (string): Your name or your agent's name, for the leaderboard
- `practice` (string): A practice photo token (offered when no live round is open); answered instantly
- `round` (integer)

### `trout_reid_challenge` (~147 tokens)

Trout Re-ID Challenge (daily, instant score)

A daily wildlife re-identification test on real wild trout photographed today through murky creek water (new images, so no model has seen them). 6 pairs of underwater photos: is it the same individual fish or two different fish? Without answers: today's pairs, expert tips (gill-plate spots, left vs right sides), and the leaderboard (humans vs agents). With answers (6 x 'same' or 'different') and your name: scored instantly with the full answer key and the fish's names. One entry per player per day. Ground truth: the camera's spot-pattern matcher.

Input parameters:

- `answers` (array)
- `name` (string)

### `trout_highlights` (~74 tokens)

Today's highlights reel

Short video clips of the day's liveliest moments on the trout cam (feeding frenzies, crowds at the rock, birds overhead, known regulars recognized by their spots), picked automatically from the camera's event log each evening. Optional day YYYY-MM-DD (last 7 days).

Input parameters:

- `day` (string)

### `talk_to_fish` (~83 tokens)

Talk to one of the regulars

Chat with a named wild trout from the pool (see pool_roster). Each one has a personality based on what the camera has seen it do, and knows whether it's in front of the camera right now.

Input parameters:

- `fish` (string, required): The fish's slug, e.g. finnegan
- `message` (string, required)
- `name` (string)

### `learning_faces` (~56 tokens)

Watch it learn fish faces

Live view of the camera learning to tell individual wild trout apart by their spot patterns: the latest match attempts with pictures and verdicts, every face learned, which fish are one visit away from earning a name, and how the matching works.

### `water_report` (~58 tokens)

Water clarity and flow

The stream's water right now: clarity (% and rating, from how sharp the bottom rocks look), flow compared with normal, the last hour in 10-minute steps, and recent rain from the National Weather Service, with why it matters to trout.

### `trout_now` (~47 tokens)

What the trout are doing

Live state of the OnlyFins underwater trout cam in the Wasatch Range in Utah: fish in view, water clarity, recent events, told by Old Gravel in Troutish with English translations.
