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. How we score → Why this is hard to score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- 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. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability52
- AI-judged instruction clarity (good).Pass
- 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. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management43
- Stability observed for 13 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage96
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 88% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
draw Draw on a doodle board ~1,480
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) fi…

edit_text Edit an HTML or Markdown board ~111

How do I install the PLMHub boards MCP server?
PLMHub boards is a hosted endpoint at https://plmhub.eu/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.
