## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 4 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 52/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1884 tokens (~376/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 43/100
  - Stability observed for 13 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 96/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 88% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (5)

### `open_board` (~48 tokens)

Open a new board

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

Input parameters:

- `kind` (string, required): doodle, html or markdown

### `read_board` (~58 tokens)

Read a board

Read a board: its kind and current content (the Markdown or HTML text, or the doodle's elements with their ids, roles, boxes and styles).

Input parameters:

- `board` (string, required): The board's 22-character code, or its URL

### `write_board` (~74 tokens)

Replace a board's content

Replace everything on an HTML or Markdown board. HTML: one complete document with inline CSS and JS. Markdown: GitHub-flavored. For a doodle, use `draw` instead.

Input parameters:

- `board` (string, required): The board's 22-character code, or its URL
- `content` (string, required): The new content

### `edit_text` (~111 tokens)

Edit an HTML or Markdown board

Change part of an HTML or Markdown board without resending all of it.
Ops (applied in order, all or nothing):
\- {"op": "write", "text": "..."} (replace everything)
\- {"op": "append", "text": "..."}
\- {"op": "replace", "find": "...", "replace": "..."} (find must occur exactly once)

Input parameters:

- `board` (string, required): The board's 22-character code, or its URL
- `ops` (array, required)

### `draw` (~1480 tokens)

Draw on a doodle board

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)

Input parameters:

- `board` (string, required): The board's 22-character code, or its URL
- `ops` (array, required): The ops, in order
