api record

PLMHub shows what you make to the user live in their browser, and they download it. A board is a Doodle (vector drawing), an HTML page or a Markdown document, addressed by its 22-character code or its URL.

Usually the user opened a board and gave you its code. If not, call open_board and give the user the link.

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.

  • open_board unknown never probed

    Open a new, empty board and get its link. Give the link to the user: they watch your work there and download it.

  • draw unknown never probed

    Draw on a doodle board. The user sees each call appear live in the editor. ## Doodle ops A doodle is a board (default 1280 x 720 px, origin top-left, y grows down). Send ops as `{"ops": [...]}`; they apply in order, all or nothing. The answer lists the ids each op created, in order. Address elements by id; read the board for the ids it already has. **Positions:** x, y is the CENTER of a shape or text, the top-left of a comment, the midpoint of a line. Omit them to place at the board's center. Later elements draw on top. ### Create - `{"op": "add", "role": "text" | "box" | "button" | "input" | "card" | "ellipse" | "line" | "image" | "comment" | "draw" | "triangle" | "diamond" | "star" | "frame", "x", "y", "w"?, "h"?, "id"?, ...style}` Defaults (w x h): text 160 wide, box 180x110, card 240x150 (radius 12), button 150x46, input 220x44, ellipse 140x90, line 180 long, triangle 120x110, diamond/star 120x120, image 320x200 (needs "src": URL or data: URL), frame 360x240, draw needs "path". Pass your own "id" to address the element without reading back (it must be unused). Buttons and inputs are plain shapes: give them text with `label`. - `{"op": "draw", "path": "M 10 10 L 90 90", "stroke"?, "strokeWidth"?}` freehand; path coordinates are board coordinates. - `{"op": "comment", "text", "x"?, "y"?, "w"?}` a sticky note for the human. - `{"op": "label", "id": shapeId, "text", "fontSize"? = 16, "fill"?, "labelId"?}` text centered inside a shape that follows it when the shape moves. Empty text removes it. - `{"op": "duplicate", "id", "newId"?, "dx"? = 20, "dy"? = 20}` ### Change - `{"op": "update", "id", ...style}` (fields below; "x"/"y"/"w"/"h" set position and size) - `{"op": "move", "id", "dx", "dy"}` or `{"op": "move", "id", "x", "y"}`; moving a frame moves its children too. - `{"op": "reorder", "id", "to": "front" | "back" | "forward" | "backward"}` - `{"op": "delete", "id"}` · `{"op": "clear"}` removes everything. ### Style fields (add and update) fill, stroke, backgroundColor (CSS colors) · strokeWidth · opacity 0..1 · angle (degrees) · radius (corner radius; or rx, ry) · borderStyle "solid" | "dashed" | "dotted" | "dashdot" or strokeDashArray [numbers] · shadow "none" | "soft" | "medium" | "hard", {color, blur, offsetX, offsetY} or null · gradient {"type": "linear" | "radial", "stops": [{"offset": 0, "color": "#6366f1"}, {"offset": 1, "color": "#ec4899"}], "coords"?: 0..1 units} (replaces fill) · flipX, flipY, skewX, skewY · text, fontSize, fontFamily, fontWeight, fontStyle ("italic"), textAlign, underline, linethrough, lineHeight, charSpacing, padding · name (layer name), visible, locked (true/false). ### Structure - `{"op": "group", "ids": [2 or more], "name"?, "groupId"?}` returns the group id. `{"op": "ungroup", "group": groupId}` or `{"op": "ungroup", "ids": [...]}`. - `{"op": "wrap", "ids": [...], "direction"?, "justify"?, "align"?, "gap"?, "padding"?, "frameId"?}` puts the elements in a new auto-layout frame and returns its id. `{"op": "unwrap", "id": frameId}` removes the frame and keeps its children. - `{"op": "reparent", "ids": [...], "frame": frameId}` moves elements into a frame; `"frame": null` takes them out. - `{"op": "layout", "id": frameId, "mode"?: "block" | "flex", "direction"?: "row" | "col", "justify"?: "start" | "center" | "end" | "between", "align"?: "start" | "center" | "end" | "stretch", "gap"? = 16, "padding"? = 16, "wMode"?, "hMode"?: "hug" | "fixed", "w"?, "h"?}` A flex frame lines its children up (row = left to right, col = top to bottom) and hugs them, or keeps the fixed w/h. A block frame leaves children where they are. - `{"op": "size", "id", "w"?, "h"?: "fixed" | "hug" | "fill", "minW"?, "maxW"?, "minH"?, "maxH"?}` how a child of a flex frame sizes; fill shares the frame's spare room; null clears a min/max. ### Board - `{"op": "bg", "color": "#f8fafc"}` or `{"op": "bg", "src": imageUrl}` (an image behind everything). - `{"op": "board", "w"?, "h"?, "autoH"?: true, "padding"?, "minH"?, "maxH"?}` autoH grows the board to fit its content plus padding, within minH..maxH. Errors name the failing op (`ops[2] (move): ...`): 400 for a bad field, 404 for an unknown id, 409 for an id already in use. Fix that op and send the batch again.

_ 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 8cab5bea31e0878b.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/8cab5bea31e0878b/claim. Over MCP: the claim_endpoint tool.

[![measured by brick.blue](https://brick.blue/api/v1/agents/8cab5bea31e0878b/badge.svg)](https://brick.blue/agent/8cab5bea31e0878b?ref=badge)

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
90%

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.
