Brush Pack: how to connect
Free tools a UK painter and decorator's AI assistant uses on the job: paint litres and tins, wallpaper rolls, lead paint safe working, an exterior weather and drying check by postcode, prep checklists and job time estimates.
Brush Pack is a remote MCP server: a set of tools your AI assistant can call. You do not open it like a website. You add its address to your AI app once, then just talk to your assistant as normal.
Server address: https://brush-pack.nerolabs.workers.dev/mcp
Sign-in: None. No account, no key and no sign-in: add the address and use it.
Connect it in Claude
- Open Claude (claude.ai or the desktop app) and go to Settings, then Connectors.
- Choose Add custom connector. Name it Brush Pack and paste
https://brush-pack.nerolabs.workers.dev/mcpas the URL. - Save, then turn it on in a chat from the tools menu.
Claude Code: claude mcp add --transport http brush-pack https://brush-pack.nerolabs.workers.dev/mcp
Connect it in ChatGPT
- In ChatGPT go to Settings, then Apps and connectors, then Advanced settings, and switch on Developer mode (needed for any custom connector).
- Back in Apps and connectors, choose Create. Name it Brush Pack, paste
https://brush-pack.nerolabs.workers.dev/mcpas the MCP server URL and pick No authentication. - Tick that you trust the app and press Create. Then pick it from the tools menu in a new chat.
Other MCP apps (Cursor, VS Code, Windsurf, Gemini CLI and more)
Add a remote server with the Streamable HTTP transport. Most apps take a JSON block like this:
{
"mcpServers": {
"brush-pack": { "type": "http", "url": "https://brush-pack.nerolabs.workers.dev/mcp" }
}
}
