Common questions
Is Gud API MCP safe?
It passed 1 of 1 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 on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.1.3) reached the registry 4 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.
What can I use instead?

Gud API
A lightweight, full-featured API client built into your editor. Test REST and GraphQL APIs, organize requests into collections, manage environments, and generate code snippets — without switching to Postman or another external tool.
Install from Open VSX or the VS Code Marketplace. Site: gudapi.gudlab.org.
Source
The editor extension is proprietary. This repository is the public home for product docs and issues. It does not contain the VS Code / Open VSX extension source.
If you followed the GitHub link from the Marketplace or Open VSX, you are in the right place for bugs and feature requests. There is nothing here to clone for the UI.
The companion MCP server is public: @gudlab/gud-api-mcp, source in gudlab/gud-api-mcp. Docs: gudapi.gudlab.org/guide/ai-agents.
