## 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 2026-08-03.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS check failed: the endpoint is reachable over plaintext HTTP.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 40/100
  - Verified sse transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 75/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 980 tokens (~140/item across 7 items; 6 tools + 1 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 74/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 21% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.
  - Supports UI / widget rendering.

## MCP tools (6)

### `search` (~209 tokens)

Search Editor API

Search the tldraw Editor API spec by writing JavaScript that receives a `spec` object and returns a result. The spec contains: spec.members (all Editor methods/properties with name, kind, signature, description, category), spec.categories (category names), spec.types.shapes (focused shape type definitions with props), spec.types.shapeTypes (list of all shape type strings), spec.helpers (exec helper functions with descriptions, params, examples).

Examples:
\- Find shape methods: return spec.members.filter(m => m.category === "shapes").map(m => ({ name: m.name, signature: m.signature }))
\- Get arrow shape props: return spec.types.shapes.find(s => s.shapeType === "arrow")
\- List all categories: return spec.categories
\- Find a helper: return spec.helpers.find(h => h.name === "createArrowBetweenShapes")

Input parameters:

- `code` (string, required): JavaScript code that receives `spec` and returns a result. Must use `return` to produce output.

### `exec` (~484 tokens)

Execute Code

Execute JavaScript code on a tldraw canvas. The code runs in the widget with access to the live `editor` instance, helper functions, and normal js. Use the `search` tool first to discover available Editor methods and shape types.

Each canvas has a unique `canvasId`. Omit `canvasId` to create a new blank canvas. To edit an existing canvas, pass the `canvasId` that was returned by a previous exec call.

Shapes and text grow depending on the amount of text they have. Use clever scripting to ensure there are no unintended overlaps.

Examples:
\- Create a rectangle: editor.createShape({ _type: 'rectangle', shapeId: 'box1', x: 200, y: 120, w: 320, h: 180, text: 'Hello' })
\- Connect shapes with an arrow: editor.createShape({ _type: 'arrow', shapeId: 'a1', fromId: 'box1', toId: 'box2', x1: 0, y1: 0, x2: 100, y2: 0 })
\- Select and zoom: editor.select('box1'); editor.zoomToSelection()
\- Read shapes: return editor.getCurrentPageShapes()
\- Distribute evenly: editor.distributeShapes(editor.getSelectedShapeIds(), 'horizontal')
\- Box around shapes: boxShapes(['box1', 'box2'], { text: 'Group label', color: 'blue' })
\- Stack shapes dynamically: editor.createShape({ _type: 'rectangle', shapeId: 'a', x: 0, y: 0, w: 300, h: 200, text: 'First box\nwith wrapping text' }); const bounds = editor.getShapePageBounds('a'); editor.createShape({ _type: 'rectangle', shapeId: 'b', x: 0, y: bounds.maxY + 20, w: 300, h: 200, text: 'Below first' })

Input parameters:

- `canvasId` (string): Canvas ID to edit. Omit to create a new blank canvas. Pass a canvasId from a previous exec result to continue editing that canvas.
- `code` (string, required): JavaScript code to execute. Has access to `editor` (tldraw Editor instance) and helper functions.

### `_exec_callback` (~51 tokens)

Exec Callback

App-only: widget calls this to resolve a pending exec request.

Input parameters:

- `channel` (string, required)
- `error` (string)
- `execKey` (string)
- `result` (object)

### `_get_canvas_state` (~33 tokens)

Get Canvas State

App-only: get the latest checkpoint for a canvas by its canvasId.

Input parameters:

- `canvasId` (string, required)

### `read_checkpoint` (~27 tokens)

Read Checkpoint

App-only: read shapes from a checkpoint by ID.

Input parameters:

- `checkpointId` (string, required)

### `save_checkpoint` (~72 tokens)

Save Checkpoint

App-only: save shapes to a checkpoint (from user edits). shapesJson and assetsJson must be JSON array strings.

Input parameters:

- `assetsJson` (string)
- `bindingsJson` (string)
- `canvasId` (string)
- `checkpointId` (string, required)
- `shapesJson` (string, required)
