Find amigurumi patterns
search_toys Searches the free patterns in the amigurumi.ai catalog and shows them as cards with the picture, height, time, hook and yarn.
| Parameter | Type | What it does |
|---|---|---|
| query | string | Words to match: an animal, character, food or colour, up to 100 characters. Leave out to browse. |
| size | small | medium | large | Finished height: under 10 cm, 10–20 cm, over 20 cm. |
| maxHeightCm | number | Only toys at most this tall, up to 100 cm. |
| maxDifficulty | 1 | 2 | 3 | Beginner, easy or intermediate. |
| noSew | boolean | Only toys whose parts are crocheted on, with nothing to sew. |
| category | animals | fantasy | sea | food | plants | One catalog category. |
| colours | array, up to 3 | Yarn colours the toy must have: red, orange, yellow, green, blue, purple, pink, brown, white, grey, black. |
| time | evening | weekend | week | How long it takes: up to 4 h, up to 9 h, longer. |
| sort | best | new | popular | Order of the results. |

| lang | en | ru | Language of the cards; taken from your ChatGPT locale when left out. |
Returns: The number of matches and up to 24 toy cards with links to each pattern. With no match it suggests a spelling or fewer filters.

get_toy Opens one toy from the search: its 3D model to turn around, size, difficulty, hook, yarn weight and every colour with the metres it needs.
| Parameter | Type | What it does |
|---|---|---|
| id* | string | The toy id from search_toys. |

Returns: One toy card with links to the full round-by-round pattern and to crochet mode, the round counter on amigurumi.ai.
Amigurumi shape calculator
circle_calculator Works out the rounds for a flat circle, a stuffed ball or a tube of the size you want: single crochet in a spiral from a magic ring, with staggered increases and decreases.
| Parameter | Type | What it does |
|---|---|---|
| shape* | circle | ball | tube | A flat disc, a stuffed sphere, or a closed end with straight sides. |
| diameterCm* | number | Finished diameter, up to 60 cm. |
| lengthCm | number | Tube only: length from the closed end, up to 100 cm. |
| yarn | fingering | sport | dk | worsted | bulky | plush | Yarn weight; dk by default. |
| stitchesPer10cm | number 5–66 | Your own gauge: sc per 10 cm (with roundsPer10cm). |

How it behaves
- Every tool is marked read-only: none of them signs you in, writes anything or changes data on amigurumi.ai.
- Answers come from the live catalog and from ordinary arithmetic. No AI model runs on our side, so the same question gives the same numbers.
- Patterns themselves stay on amigurumi.ai: the cards link to them, and the pattern pages are free to read without an account.
- The cards are an interactive widget. In a client that cannot show widgets you get the same answer as text.
- The app only knows crochet toys and amigurumi shapes. Knitting, clothes and blankets are outside it: crocheting.ai has its own app for those.
Data and privacy
The app receives only the arguments of each tool call: search words, filters, a toy id or the sizes to calculate, and your locale so the cards come in your language. It never sees your conversation or your assistant account.
Nothing you send is stored, joined to an account or used to train models. The app sets no cookies and has no trackers.
Troubleshooting
The app answers with text but shows no cards.
Your client may not support app widgets, or they are switched off for this connector. The text answer has the same links and numbers.
The search finds nothing.
Try fewer filters or a simpler word ("bear" instead of "teddy bear with scarf"). For a toy we do not have, ask for its shapes and the calculator works out the rounds.
ChatGPT does not call the app.
Pick amigurumi.ai from the + menu in the chat, or name it in your message: "Use amigurumi.ai to find…".
The connector fails to add.
Check that the URL is exactly https://amigurumi.ai/mcp, with https and no trailing slash, and that authentication is set to none.
