Riddle
com.riddle/creator · 1.0.2
Build, publish and analyze quizzes, polls, forms and personality tests. Riddle account required.
Nobody here has read this server's code, because it publishes none. The description above is the maker's own, from the registry. A connection test shows whether it answers and what tools it says it has; it never calls a tool, so it cannot show what one does with your data.
Where it sits in the directory's order
What can be seen from outside, weighed as the directory publishes.
Observable signals: 45 of 100 points (at most 60 here)
| Input | Points | What was seen |
|---|---|---|
| Source published | held at 0 | No entry here publishes source: that is what puts it in this directory. |
| Licence stated | held at 0 | With no files, there is nothing for a licence to be stated in or held against. |
| Advisory state | held at 0 | Advisory databases index packages, and these entries publish none, so there is nothing to look up. |
| Auth declared | 0 of 15 | The registry entry declares no key. That is what it declares, not a finding that it has no protection. |

Connection test
The MCP handshake, then a request for the tool list, with no key and no data of yours. Run nightly, and by anyone, at most once every ten minutes per server.

The tools it lists (41, as of 2 days ago)
The tool-description rules found nothing in these descriptions. They look for instructions aimed at a model and for hidden characters; they cannot see what a tool does when it runs.
media_upload_linkCreates a single-use link for uploading ONE media file into the media library. Call it when the user has a LOCAL file for a Riddle: this server cannot receive bytes, so the upload is yours. A link expires after 5 minutes, dies on first use (successful or not), and only 20 are handed out per account per 5 minutes - so create one immediately before each upload, a batch one file at a time rather than the links up front, and never store or share one. Check the file BEFORE minting a link, since a link a rejected file burns is gone: an image, a video or an audio file, at most 10 MB (some environment
media_deleteDeletes a file from the media library permanently, to clean up after yourself: an upload that turned out wrong, or a file the user no longer wants stored (it frees the storage it counted against). The file must be unused - one any Riddle still shows is refused with a message naming those Riddles, since deleting it would leave a broken image behind in a live Riddle; remove it there first (riddle_builder_update, then riddle_publish so the change is live) and delete afterwards. Unused is a property of the file across the whole ACCOUNT, not of one Riddle: several Riddles can use it and any one of
riddle_template_createStores an existing Riddle as a template of its project (or of the user, for a personal Riddle), so new Riddles can be created from it with riddle_template_use. The template is a copy taken at this moment - the Riddle keeps living its own life and later changes to it do not reach the template. It copies what the Riddle currently has stored, published or not. Returns the created template: {id, title, type, category, isPublic, isQuickCreate, blocksCount, image, icon, createdAt, riddle}. Requires the template-create permission in the Riddle's project. Without full access only for a Riddle whose or
riddle_template_updateChanges a template's title and/or its gallery image and icon. Images come from the media library: upload with media_upload_link, pass the reported "mediaId" (stored by URL - deleting the file breaks the image). Only what you pass changes; the template's content cannot be changed (create a new template from the edited Riddle). Public templates only by Riddle admins. Returns the template like riddle_template_create. Without full access only for a Riddle whose origin.writableByThisKey is true: riddle://reference/concepts/access.
How this entry becomes a listing
For the maker. The catalogue lists what it can read, and this server publishes nothing to read yet. There are two routes, and only the first is open today.
Publish the source Open today
- Put the server's source in a public repository on github.com, with a licence.
- Keep a server.json in that repository naming this server,
com.riddle/creator, and declare the repository in it:"repository": { "url": "https://github.com/owner/repo", "source": "github" }, adding"subfolder"when the server lives in a folder. - Publish that version to the official MCP registry.
- The nightly registry sweep records the declaration. This page stays, dated, and says the source is declared but not yet read.
- The catalogue reads declared repositories at a pinned commit, in batches run by hand, and lists the servers that meet the batch's rules (among them a server.json at that commit naming the server, an https endpoint and a licence). When it lists this server, this page links to the listing. There is no schedule, so no date can be promised.
