A remote Model Context Protocol server that gives AI agents web superpowers — host HTML pages on a public URL, generate PDFs, capture screenshots, scrape sites, and run sandboxed code — using your own CustomJS API key.
| Endpoint | https://mcp.customjs.space/customjs/mcp |
| Transport | Streamable HTTP |
| Auth | x-customjs-api-key header (per-user API key) |
There's nothing to install or self-host — it's a hosted remote MCP server. Bring your CustomJS API key and connect.
| Tool | What it does |
|---|---|
customjs_host_html_page | Publish static HTML and get a public lp.customjs.space URL (upsert by name) |
customjs_list_html_pages | List your hosted pages (name, url, pageId) |
customjs_delete_html_page | Delete a hosted page by name or pageId |
customjs_html_to_pdf | Convert HTML to PDF (Nunjucks templating) |
customjs_markdown_to_pdf | Convert Markdown to PDF |
customjs_screenshot | Capture a full-page website screenshot |
customjs_scrape_html | Extract fully-rendered HTML (JavaScript-aware) |
customjs_run_code | Run JavaScript in a secure sandbox |
customjs_help | Built-in usage examples (topics: pages, pdf, screenshot, scraping, code) |
Create a free key at https://www.customjs.space/integration/native-api/api-key. Your key is sent per request as the x-customjs-api-key header and is never stored by the connector.
/plugin marketplace add customjs/claude-plugin
/plugin install customjs@customjs-tools
You'll be prompted only for your API key. (See customjs/claude-plugin.)

}
}
Add a remote / HTTP MCP server pointing at https://mcp.customjs.space/customjs/mcp with the header x-customjs-api-key: <your-key>.
customjs_host_html_page publishes static HTML and returns a public https://lp.customjs.space/<shortId> URL. Hosting again with the same name updates the existing page (upsert by name).
Note: the public URL is served via CloudFront, so immediately after an update it may briefly show the previous content until the cache refreshes.
This server is published to the official MCP Registry as space.customjs/customjs-mcp (DNS-verified on customjs.space) — see server.json. For how it's published and the full directory list, see PUBLISHING.md.
