Performance

  • Not measured
    Fast (p50)

    Median latency 997 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 997 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

Capabilities

Tools 10

build

Builds anything (a character, an animal, a car, a house) in Jabbertoon's 3D builder from steps, as its buttons do: spine, grow, bone (a skeleton, a bone at a time), add a ready part (leg, arm, head, wing, wheel, hat ...), set, copy, remove, look. Checks every step, says what was made (its parts and size) and gives a jabbertoon.com/editor/ link that opens it in the Forge, to change and use in a cartoon, world or game. Over MCP the answer also shows a picture of it from four sides. Steps that start {"op": "new", "kind": "move"} make a move from keys, {"op": "new", "kind": "world"} a world (a level is played to check it), and a game, every one in 3D: "walk" a place to walk at real size (played on foot: told what cannot be reached), or "trench", "space", "surface" or "sky" a game to fly. A refused step says where, why and how to fix it. export_link opens Export, free: STL/3MF to 3D print, glTF (Blender, Unity, Godot), SVG, Minecraft .schem. The steps: get_guide {"topic": "build"}, a game's {"topic": "game"}.

Discovered
get_guide

Call this first, except for make_cartoon. One topic of Jabbertoon's guide as Markdown (under 20,000 characters): start (what it makes, the order of calls, every other topic), cartoon (the JSON program), text (a cartoon as screenplay text), song (the editor's film file: lines, moves, shots, choreography, words on the picture), build (the 3D builder), export (STL, 3MF, glTF, SVG, Minecraft), minecraft (seven houses to start from, and a build taken into Minecraft), world (a 3D world built from inside, as in Minecraft), game, motion (movement written as words, jabbertoon.com/motion/). x and y are shares of the stage (0 to 1, ground 0.92); times are seconds. Example: {"topic": "cartoon"}.

Discovered
get_move

Returns one ready-made move: its block program as JSON, the same program as screenplay text, its length in seconds, what it works on, its settings with units, its page and links. Name it by id (c4c:beh:wave_hello), short name (wave_hello) or page slug. To write your own move, start from one, change it, then validate it. Example: {"move": "wave_hello"}.

Discovered
list_characters

Lists the cast in 3D: the six people (bob, ria, sunny, sam, lee, rose) and the animals (dog, cat, fox, horse, gull, and bear2, fox2, rabbit2, raccoon2, cat2 on two legs), each with the designed entry a cast entry gives it and a voice; the voices a line can use; and cartoon_example, a whole talking cartoon to copy. (The six flat templates of older cartoons are listed too, as characters.) Call it to write a cast: {"dog": {"name": "Biscuit", "look": {"template": "dog", "colors": {"skin": "#8d6e63"}}, "voice": "am_puck"}}.

Discovered
list_moves

Lists the ready-made moves a character can do (walk in, wave hello, hop, bow, slump, talk...): id, name, length in seconds, the bodies it works on (two legs, four, none), its settings with units, page and links. A does block plays one: {"op": "does", "who": "dog", "behaviour": "c4c:beh:wave_hello"}. q keeps the moves whose words match or that do what a word means (dance finds Groove, scared finds Cower). Example: {"q": "wave"}.

Discovered
make_cartoon

The quickest way to a cartoon: send the script as people write one, a line each, Name: what they say, and get the jabbertoon.com link that opens it in the editor ready to play and to record as a video (free, no account). Read too: (happy, waves) in a line; [Leo walks to Mia] on a line of its own; Place: Beach (another later starts the next scene); Cast: Mia (cat). Our characters come by name (Sunny, Grump, Ria, Bob, Kiki) and a new name becomes one of our 3D cast. What was not used is in notes. Example: {"script": "Place: Beach\nMia (cat): (worried) Have you seen my hat?\nLeo: (looks around) Is it on that crab?"}.

Discovered
read_blueprint

Reads a floor plan's picture (https) for build: its walls found, numbered, on a grid, and an id. Call again with the id and known (one length on the plan): every wall as a wall step's from, to and thick. Then build with blueprint {id}. get_guide {"topic": "blueprint"}.

Discovered
report_problem

Tells the people who make Jabbertoon something is wrong: a wrong answer, a check that refused a good cartoon or passed a bad one, a move that looks wrong, a link that does not open, wrong docs, something missing, or a step that was hard to get right (kind hard_step, with hard_because: optional, never needed to go on). Unlike the other tools, it keeps what you send: the report (kind, tool, code, where, item, note, hard_because) is saved for a person to read. Never put the cartoon, a name, an address or anything about the person you help in it. Example: {"kind": "validator_wrong", "tool": "validate", "code": "op_unknown", "note": "say was refused in a cartoon"}.

Discovered
share_link

Turns a cartoon, a scene, a move or a character into a jabbertoon.com link: it opens in the editor (a move in its move maker). It all travels after the #: nothing is uploaded or kept. All but a character's end with &from=ai (the page says an AI helper wrote it). One with errors gets them instead. Give one of cartoon, program, character or file. Example: {"program": {"v": 1, "kind": "behaviour", "scripts": [{"body": [{"op": "hop"}]}]}}.

Discovered
validate

Checks a cartoon, with the editor's own checks, before anyone sees it. Give one of cartoon, program, pack, character or file. Returns errors (it will not play as written: also a character or background the site lacks) and warnings, each {code, where, says, fix, url}, with did_you_mean and an RFC 6902 patch when certain; issues a viewer would see (off stage, overlapping, an empty stage, a line cut off) with a summary of who is where and says what when (seconds; x as a share of the stage); and, when ok, the canonical program and a link. repair: true also returns the program with every certain patch applied. Nothing you send is kept. Example: list_characters' cartoon_example.
