api record

Hypnotic Patterns teaches Python with glowing math animations: each lesson builds one pattern (the golden angle of a sunflower, the Galton board, the chaos game, Turing patterns, three-body orbits…) in a short numpy and matplotlib script, line by line. Good when someone wants to learn or teach Python, numpy or matplotlib through a small visual project, or asks about the math of one of these patterns. learning_path gives the course in order, get_lesson a lesson step by step (exercises and quiz without their answers), get_code the script, check_answer checks a quiz answer or gives an exercise’s…

_ is it live, free and safe measured by this hub
Is hypnotic-patterns live?
Yes — it answered the hub's last check (checked 43m ago). It answered 100% of checks over the last 30 days.
Is hypnotic-patterns free to use?
Yes — the hub reached it with no key and no payment.
What tools does hypnotic-patterns have?
6 tools: get_lesson, get_code, explain_concept, check_answer, list_patterns, learning_path.
Is hypnotic-patterns safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • list_patterns open 43m ago

    The patterns of the channel: each one simple rule (the golden angle, the Galton board, Turing patterns…), its category, whether it has a Python lesson and at what level, with links to its page and newest video.

  • learning_path open 43m ago

    The free Python course in its order: each lesson builds one pattern in a short numpy/matplotlib script, from arrays and loops (Beginner) to randomness and recursion (Intermediate) to simulations and grids (Advanced). Each lesson with what it teaches and its link. Optionally only one level.

  • get_lesson unknown never probed

    One lesson of the course: the question the pattern asks, why it works at three depths, the formula, its script line by line with explanations, exercises with hints, a quiz and flashcards. Exercise answers and quiz keys are left out on purpose: use check_answer once the learner has tried.

  • check_answer unknown 43m ago

    For a quiz question of a lesson: says whether the answer is right, which option is, and why. For an exercise: gives its hint and its reference answer to compare the learner’s attempt with (this server does not grade free text and never runs code); offer the hint first and the reference only after a try.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 7d5b781a99bf6226.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/7d5b781a99bf6226/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
