UserScripts Claude.ai di losnappas

Check the readme on https://github.com/losnappas/userscript-mcp-claude-webextension for usage notes.

Here it is for brevity, but I'm unlikely to update these steps here, just on the readme:

Preliminary step: log into https://claude.ai, if you aren't already
Go to a page where you want to have a user script, e.g. https://example.org
Hit the extension button
Claude.ai opens in a new tab, and it has access to an MCP
Ask Claude to, for example, "make a user script to turn the background green"
Claude goes off, it will write the scripts, and instruct you to refresh example.org once done


Here are some chats with claude, for show:

• Basic "change background to green" example - https://claude.ai/share/53bf39b3-823a-4de9-a6cb-cb4632bc5032
• Fill reddit username (longer) - https://claude.ai/share/33b465ff-814e-4772-a75f-c943a4551ab0
• Had a mixup with claude (multiple iteration debug) - https://claude.ai/share/b9ddaae5-0f2d-47cd-8947-f2f18a5b4d2a
