PromptUI is a remote MCP server that gives an AI agent 12 tools, among them build_app, db_query, deploy_app. It answers at https://www.promptui.co/api/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 4 September 2026; the last check, on 17 October 2026, succeeded.
Build a working web app from a prompt, then deploy it to a live URL.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
build_app | Build a working web app from a prompt with PromptUI. Starts an asynchronous build (costs credits from the authenticated account) and returns a buildId — poll get_build_status for progress and the preview link. Inputs: prompt, mode, framework |
db_query | Execute a read-only SQL query against the project database (Supabase/PostgreSQL) Inputs: query, connectionString |
deploy_app | Deploy a completed PromptUI build to a live URL. The first deploy of each app is charged; redeploying that same app is free. Inputs: buildId |
echo | Echo back the input (for testing MCP integration) Inputs: message |
get_build_status | Check the status of a PromptUI build started with build_app. Returns building / needs_clarification / completed (with a shareable previewUrl) / failed. Inputs: buildId |
gtm_generate_content | Generate and persist a new GTM content draft for the authenticated user. Inputs: channel, deliverableType, contentClass, count, appSource, campaignId |
gtm_get_analytics | Read current PromptUI GTM channel analytics. X and YouTube can include live public metrics; other channels use PromptUI publish history. |
gtm_list_content | List GTM queue items for the authenticated PromptUI user. Inputs: status, channel, campaignId, limit |
gtm_publish_content | Publish one GTM content item to a connected social platform. Inputs: contentId, platform, pageId, igUserId |
list_builds | List the authenticated user's recent PromptUI builds with their statuses. Inputs: limit |
shadcn_ui | Get production-quality shadcn/ui component code pre-adapted for the Sandpack preview environment. Available components: accordion, dropdown_menu, dialog, sheet, tooltip, progress, separator, scroll_area, skeleton, alert. Returns ready-to-us Inputs: component |
web_scout | Research the live web: search for information, read documentation, fetch API references, or verify library usage. Returns structured findings as markdown. Inputs: goal, urls, maxPages |

It answered our last check on 17 October 2026 in 337 ms. Over 10 checks since 4 September 2026 it answered 10. Status here comes from Neuronto's own probes, not from the publisher.
Yes. It is published by promptui.co and served from www.promptui.co, the vendor's own domain: https://www.promptui.co/api/mcp.
12, as returned by the server's own tools/list on 1 September 2026: build_app, db_query, deploy_app, echo, get_build_status, gtm_generate_content, gtm_get_analytics, gtm_list_content, and 4 more.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://www.promptui.co/api/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 1 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
