PLMHub MCP server

Which MCP servers are PLMHub's own, from the official registry and from asking its own domain, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

Whose server it is
  • Registry nameeu.plmhub/boardsverified in the MCP registry

The registry name sits under plmhub.eu. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-28 the server answered initialize and tools/list without a sign-in. First answer in 635 ms.

Should an agent connect itNot proven either way yet
  • Whether its tools do the product's job has not been judged yet.
  • Checked on 5 of the 7 days it takes to judge reliability.

Once connected

  • For "Generate a landing page draft and tweak it", the likely first call is open_board.
  • write_board, edit_text change data without a sign-in: anyone with the address can call them.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

Each of the product's use cases, put to Jev against this server's tool list: can an agent do it with these tools?

Worth a look

  • Tools that change data, on a server that answers without a sign-in: write_board, edit_text

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

Tools it offers5 tools · read 2026-10-28
  • open_board

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

  • read_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).

  • write_board

    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.

  • edit_text

    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": "..."…

  • draw

    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…

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "boards": {
      "type": "http",
      "url": "https://plmhub.eu/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http plmhub https://plmhub.eu/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://plmhub.eu/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
