MCP100 verdict
Not currently recommended. Community implementation with resolved registry identity, active maintenance, strong public adoption, differentiated design-system task value, and no reviewed admission veto.

Evidence-backed setup
Choose your MCP client. A client connects to the MCP server; the language model is selected inside that client. Only stored, source-backed configurations are shown.
Transport not recorded
Complete client-specific setup, verification and removal are not documented in this reviewed source.
Publisher-documented setup is not the same as MCP100 execution testing. “MCP100 logic checked” means the stored configuration shape was reviewed, not that third-party MCP software was run.

{"command":"npx","args":["-y","dembrandt","mcp"],"prerequisite":"Install/configure a supported Chromium browser as documented"}Capability
Dembrandt is a community/open-source design-system extraction tool with an MCP server for token extraction, drift analysis and design reporting. The tool drives a local browser against websites and may process third-party brand assets/content. Respect robots.txt and site terms; only analyze sites you own or have permission to inspect. Setting DEMBRANDT_KEY uploads snapshots to the Dembrandt cloud service.
Current official source registers 21 MCP tools; this replaces the earlier incomplete 13-tool list.
Not measured yet

Dembrandt is listed as Community implementation in MCP100’s current evidence.
Current implementation resources:
From the publisher README
Original client setup and configuration retained from the publisher documentation.
Publisher-documented clients
These names appear in the publisher's installation documentation. MCP100-verified configurations are shown separately above when available.
Claude Code:
claude mcp add --transport stdio dembrandt -- npx -y dembrandt mcp
Claude Desktop, Cursor, Windsurf and any client that reads a JSON config:
{
"mcpServers": {
"dembrandt": {
"command": "npx",
"args": ["-y", "dembrandt", "mcp"]
}
}
}
Claude Desktop: Settings, Developer, Edit Config, paste the block inside mcpServers, restart. Cursor and Windsurf: .mcp.json at the repo root. VS Code and Copilot: .vscode/mcp.json with the same server under servers.
Codex:
codex mcp add dembrandt -- npx -y dembrandt mcp
The server runs on the machine that runs the agent. Web agents without a local process (ChatGPT, Perplexity, Claude.ai, Lovable, Figma Make) cannot connect to it. Claude Code can also take the skills repo as a plugin, which registers this server alongside 45 UX skills: /plugin marketplace add dembrandt/dembrandt-skills.
Original product, capability, tool, and usage documentation from the MCP publisher. Installation sections appear under Install & Agents.
Dembrandt runs as a Model Context Protocol server, so an agent can call extraction and analysis as tools. It is listed in the MCP Registry as io.github.dembrandt/dembrandt.
| Variable | Effect |
|---|---|
DEMBRANDT_KEY | API key from dembrandt.com/app/api-keys. Uploads each extraction as a snapshot and scores it against the previous one for that domain. |
BROWSER_CDP_ENDPOINT | Connect to a running Chromium over CDP instead of launching one, e.g. http://localhost:9222. |
Extraction tools: get_design_tokens, get_color_palette, get_typography, get_component_styles, get_surfaces, get_spacing, get_brand_identity. Each accepts slow, mobile, darkMode, wcag, cookie, cookieFile, basicAuth, header, userAgent, noSandbox, pages, paths and sitemap. Interactive --login stays CLI-only.
Extraction returns a job_id. Poll it with get_job_status, then hand the id to the pure tools instead of passing the extraction back as an argument: compute_drift, get_findings, export_dtcg, generate_design_md, render_report.
The server honours robots.txt the same way the CLI does; see ci.md for DEMBRANDT_ENFORCE_ROBOTS.
