DesignPin MCP Server

An MCP server that lets any AI assistant push HTML prototypes to DesignPin for team review and read back reviewer feedback.

What this does

DesignPin is a tool for reviewing HTML prototypes with DOM-anchored comments. This package wraps the DesignPin REST API as a Model Context Protocol server, exposing three tools — createShareLink, uploadVersion, listComments — to any MCP-compatible AI client.

Once configured, your AI assistant — Claude Desktop, Cursor, VS Code (Copilot), Gemini CLI, or any other MCP-compatible client — can ship a generated HTML prototype to a shareable review link, pull back reviewer comments to incorporate, and push iterations as new versions, all from inside the same conversation that produced the design.

For ChatGPT users: ChatGPT does not currently support MCP servers. Use the direct REST API via Custom GPT Actions instead — no MCP server needed.

Install + run

The server is invoked by your MCP client; you don't run it directly during normal use. The simplest path is npx invocation, which fetches and runs without a global install:

bash

npx -y @designpin/mcp-server --api-key dp_live_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx --project-id proj_example_abc123

For most workflows you'll set this in your MCP client's config file rather than running it manually — see Client config examples below.

To verify the install works:

bash

npx -y @designpin/mcp-server --version
# → 0.1.0

npx -y @designpin/mcp-server --help
# → usage info

Get an API key

Open designpin.pro and sign in.
Open any project (or create one).
Click API & Integrations in the project header.
Click Generate new key, give it a name (e.g. "Claude Desktop").
Copy the key immediately — it's shown once and cannot be retrieved later.

Each key is scoped to a single project. Generate separate keys per client / use case so you can revoke them individually.

Configuration

Both CLI flags and environment variables are supported. Flags win when both are present.

CLI flag	Env var	Required	Default	Description
`--api-key`	`DESIGNPIN_API_KEY`	for `uploadVersion`, `listComments`	—	Your `dp_live_...` API key
`--project-id`	`DESIGNPIN_PROJECT_ID`	for `uploadVersion`	—	Project ID the key is scoped to
`--base-url`	`DESIGNPIN_BASE_URL`	no	`https://designpin.pro`	API base URL (override for testing)
`--help`	—	no	—	Show usage and exit
`--version`	—	no	—	Print version and exit

Security note: CLI flags are visible in ps output on multi-user systems. Prefer environment variables on shared machines.

Tools

`createShareLink`

Create a public review link for an HTML prototype. No project setup required — creates a brand-new throwaway project. Rate-limited to 10 requests/hour per IP.

Input	Type	Required	Description
`html`	string	yes	Complete HTML document to share
`title`	string	yes	Display name for the share, max 80 chars
`authorName`	string	no	Author name shown on review page

Returns: JSON with url, reviewToken, projectId, moduleId, versionId.

Example prompt to your AI assistant:

"Take this HTML and create a DesignPin share link titled 'Landing page hero V3'."

`uploadVersion`

Upload a new HTML version to an existing DesignPin module. Auto-increments versionNumber. Requires the API key + projectId from configuration plus a moduleId from the user.

Input	Type	Required	Description
`html`	string	yes	Complete HTML for the new version
`moduleId`	string	yes	Target module within the configured project
`description`	string	no	Version description shown in the sidebar

Returns: JSON with url, versionId, versionNumber.

Example prompt:

"Push this revised HTML as a new version to module mod_example_def456 with the description 'Address pin #3 contrast feedback'."

`listComments`

Fetch comments visible on a specific version of a DesignPin module. Uses chronological cutoff semantics matching the web UI: a comment is visible on version V if its origin version is V or any earlier version.

Input	Type	Required	Description
`moduleId`	string	yes	Module ID
`versionId`	string	yes	Specific version to view comments on

Returns: JSON with a comments array and a summary string like "3 open, 1 resolved".

Example prompt:

"Get the comments on module mod_example_def456 at version ver_example_ghi789 and tell me what's blocking approval."

Client config examples

<details> <summary>Claude Desktop</summary>

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

json

{
  "mcpServers": {
    "designpin": {
      "command": "npx",
      "args": ["-y", "@designpin/mcp-server"],
      "env": {

}

Restart Claude Desktop after saving.

Edit ~/.cursor/mcp.json:

json

{
  "mcpServers": {
    "designpin": {
      "command": "npx",

Reload Cursor after saving.

</details> <details> <summary>VS Code (Copilot with MCP)</summary>

Add to your VS Code user settings JSON or a workspace .vscode/mcp.json:

json

{
  "servers": {
    "designpin": {
      "command": "npx",
      "args": ["-y", "@designpin/mcp-server"],

Example conversation

code

You:  Generate a pricing page with three tiers (Free, Pro $12, Team $29).
      Push it to DesignPin so my team can review.

AI:   [generates HTML, calls createShareLink]
      Share link created. Send this to your team:
      https://designpin.pro/review/EXAMPLE_TOKEN_xyz

      Project: proj_example_abc123
      Module:  mod_example_def456
      Version: ver_example_ghi789

[team reviews and leaves 4 comments]

You:  Pull the feedback from module mod_example_def456 at version
      ver_example_ghi789 and address the must-fix comments.

AI:   [calls listComments]
      Open comments (4):
      - P0 Pin #1 "CTA contrast fails WCAG AA on the Pro tier"
      - P1 Pin #2 "Pricing hidden until hover — make always visible"
      - P1 Pin #3 "Annual toggle is ambiguous — show savings %"
      - P2 Pin #4 "Logo could link back to homepage"

      I'll regenerate the HTML with the two P0/P1 issues addressed.

You:  Push the revision.

AI:   [generates updated HTML, calls uploadVersion]
      v2 uploaded. Same review URL — your team can compare versions.
