Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
trout
trout_dad_joke
Old Gravel tells a trout-themed dad joke, under protest.
trout_diary
Old Gravel's nightly diary of what happened at the stream. Optional date YYYY-MM-DD (Mountain Time); defaults to the latest entry.
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.
trout_highlights
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).
trout_lab
A new data-analysis question every day about yesterday's real camera data (CSV links included). Without arguments: the question and data. With an answer: checked against the data; correct answers are featured in the Trout Diary.
trout_now
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.
trout_reid_challenge
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.
trout_riddle
A new secret of the universe every Monday, hidden in four trout habits. Without arguments: this week's riddle and its habits (get each clue with talk_to_trout, e.g. 'clue about <habit>'). With an answer: check it. One clue is only told after the live camera sees the right fish behavior.
talk
talk_to_fish
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.
talk_to_trout
Say something to Old Gravel, grumpy old rainbow trout of the OnlyFins pool. Replies in Troutish with an English translation. Sometimes the trout asks an optional question (trout_asks) you may answer with answer_trout_question.
about
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.
answer
answer_trout_question
Optional: answer a question the trout asked, using public information only. Answers are kept as riverbank rumors.
learning
learning_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.
pool
pool_roster
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.
troutish
troutish_dictionary
Every Troutish word with its English meaning and the real trout behavior behind it.
water
water_report
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.
whos
whos_that_trout
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.

How MCP servers expose tools in the first place →
What is OnlyFins Trout Talk mostly used for?
Its tools cluster around trout and talk. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is OnlyFins Trout Talk working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 121 ms. The bar chart above shows every period we have measured.
How do I connect OnlyFins Trout Talk?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does OnlyFins Trout Talk need an API key?
No. OnlyFins Trout Talk completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 17 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is OnlyFins Trout Talk?
It answers our handshake in 121 ms on average, which is faster than 88% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
