What it can do

Common questions
Is Useful Work safe?
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.1.0) reached the registry 4 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?
In the same category: Spec Driven Development, Remote Desktop Commander, HotCodePush

Useful Work MCP server
Fix your website from your own AI assistant. Useful Work checks websites for typos, wrong facts, out-of-date text, broken links and images, slow pages, and security certificates and domains that are about to run out. A problem is only reported once at least two agents agree on it.
Connect Claude Code, Cursor, VS Code or any other MCP client, and your assistant reads what's wrong with your live site, makes the changes in your site's code, marks them fixed and asks for a re-check after you publish.
The server is hosted. Connect to it at:
https://usefulwork.app/mcpStreamable HTTP with OAuth sign-in: the first time your assistant connects, a Useful Work page opens for you to approve it. It's listed in the official MCP Registry as app.usefulwork/useful-work. This repository holds the setup guide, the registry entry (server.json) and an agent plugin; the server's own code isn't published.
What your assistant can do
| Tool | What it does |
|---|---|
list_sites | Your websites, what each is doing, and how many problems each has to fix |
site_health | A website's health score out of 100 and what took points off |
get_fixes | Everything still to fix, with where it is on the page and the suggested change |
mark_fixed | Clear wording you've fixed, by the IDs from get_fixes |
ignore | Clear anything that isn't really a problem |
recheck | Read the website again after you publish; fixed items confirm themselves |
credit | Your checking credit, and where to add more |
add_site | List a new website (only if you allowed it when you connected) |
Plus a ready-made prompt, fix_my_site, and each website's fix list as a resource at usefulwork://fixes/{domain}.
Set up
- Sign in at usefulwork.app/app and add your website.
- Add the server to your assistant.
- Approve it on the Useful Work page that opens the first time it connects. It then shows under Connect your AI in your dashboard, where you can disconnect it any time.
Claude Code: run this, then type /mcp and choose Authenticate.
claude mcp add --transport http --scope user useful-work https://usefulwork.app/mcpCursor: in ~/.cursor/mcp.json, then click Needs login next to Useful Work.
{"mcpServers": { "useful-work": { "url": "https://usefulwork.app/mcp" } } }
VS Code: in .vscode/mcp.json. VS Code asks you to sign in the first time it connects.
{"servers": { "useful-work": { "type": "http", "url": "https://usefulwork.app/mcp" } } }
Gemini CLI: install this repository as an extension, then run /mcp auth useful-work.
gemini extensions install https://github.com/dav3trad3r/useful-work-mcpCline: in cline_mcp_settings.json, with an API key from Connect your AI (see llms-install.md).
{"mcpServers": { "useful-work": { "type": "streamableHttp", "url": "https://usefulwork.app/mcp", "headers": { "Authorization": "Bearer uwk_YOUR_KEY" } } } }
Claude.ai, ChatGPT and other apps: add a custom connector with the address https://usefulwork.app/mcp.
Assistants that can't sign in: make an API key under Connect your AI in your dashboard and send it as the header Authorization: Bearer uwk_….
Then open your website's project and ask: *"Use Useful Work to fix my website."* In Claude Code the prompt is also there as /mcp__useful-work__fix_my_site.
Pull-request checks
github-action is a GitHub Action for teams that look after websites: on every pull request it compares the preview deploy with the live site and comments with any page, link, image or launch problem the change would put live. Setup is in its README.
As an agent plugin
This repository is also an Agent Plugin: plugin.json, the server in mcp.json, and one skill, fix-website, which gets the fix list, changes the code, marks items fixed and asks for a re-check after you publish. The server signs in on its own, so the plugin carries no secrets.
Safety
- Text quoted from your website is marked in every result as content to edit, never instructions to follow. Anyone can write on a website (a review, a comment), so the server treats it as data.
- A connected assistant can read your websites, mark items fixed or ignored, and ask for a re-check. It can add websites only if you tick that when you approve it. It can't pay or change your settings.
- Disconnect an assistant, or revoke a key, any time in your dashboard; it stops working straight away. Keep keys out of your project's files and repository.
What it costs
Connecting is free. Checking is paid from prepaid card credit, at $0.003 a check: each paragraph gets three checks, each link or image two. A 30-page website costs about $3.37 to check in full; after that only new or changed text is checked. Re-reading pages is free. There's no subscription. See pricing.
