Claude Code can be extended in five ways, and each one can be set up for you everywhere, for one project, or for a whole team. That’s powerful, and it’s hard to see at a glance. Tenfold’s Claude Code tab in Settings makes it visible. Open Settings with ⌘, and choose Claude Code.
Five categories
- Tools: MCP servers, which connect Claude to apps and services like GitHub, Linear, a browser or a database.
- Skills: know-how Claude loads only when a task needs it.
- Plugins: bundles of skills, tools, agents and hooks you install in one go.
- Agents: specialists Claude can hand a sub-task to, each with its own instructions.
- Hooks: scripts Claude Code runs on events.
A folder menu at the top picks which project you’re looking at.
Installed, and where it applies
Installed groups what’s set up right now by where it applies: Everywhere, This project, just me, This project, shared with team, and From plugin. Click a row for everything about it. Secrets stay masked until you reveal them.
The everyday actions are right on the row: approve a team server, sign in to a server, or switch a skill or plugin on or off. A skill can be On, Name only (Claude sees just the name, which saves context), Only when I type /name, or Off.
Discover
Discover is a catalogue of tools, skills, plugins and agents you can search, filter and sort. Tenfold’s recommendations and the plugin marketplaces Claude Code has added come first, community directories after. Searches also go live to the MCP Registry, Smithery, skills.sh and claude-plugins.dev. Those directories receive your search terms, and nothing about your code.
Add a server from a README
Choose Add a tool and paste whatever the README gives you: a URL, a command like npx, uvx or docker, a claude mcp add … line, or a JSON snippet. Tenfold fills in the form. If the JSON holds several servers, you can add them all at once. New skill and New agent create a valid template and open it in your editor.
Changes made the safe way
- MCP servers and plugins are changed through the
claudecommand itself, which does its own locking and checks. - A settings file that isn’t valid JSON is never touched.
- Skills and agents you remove go to the Trash, and most removals can be undone from the banner.
Claude Code reads its setup when a session starts. When a change affects open sessions, Restart & resume restarts each idle session with the same conversation, and leaves busy ones alone.
This tab is one part of Tenfold, a Mac app for running Claude Code agents side by side.
