Apps

Connect the apps your agents work in

Connect Stripe, GitHub, Notion or Linear once for your workspace. Then give each agent only the tools it needs, with a permission for every one, so anything risky still asks you first.

Most of these apps connect by signing in with your account on the app, so there's no key to find. A few, like GitHub, take an API key instead. Connect shows which ways each app takes.

Connecting an app

Once for your whole workspace

Apps connect through the app's own MCP server, the standard way AI agents reach an app's tools. You don't need to know what that is: pick the app, then sign in to it or paste its key.

  1. 1

    Pick the app

    Choose it from the catalog, search the public MCP Registry for thousands more, or add your own company's server.

  2. 2

    Sign in, or paste a key

    Most apps let you sign in with your own account and approve LoopEngine on their site. For the rest, paste an API key. Either way it's stored in your workspace, never shown again, and only that app's tools use it.

  3. 3

    Every tool is ready

    All of the app's tools become available to your workspace, each with a safe default: reading is allowed, anything that changes something asks you first.

…and 38 more. New tools the app adds later show up here too, at their default.

Choosing tools per agent

Each agent gets only what its job needs

When you add an app to an agent, you choose which of its tools that agent can use, and what each may do on its own. A support agent can read issues; only your release agent can open pull requests.

  • Each agent gets only the tools you tick, nothing else from the app
  • Set each tool to Allow, Ask me or Never, for that agent alone
  • Start from the safe defaults, or select all the read-only tools in one click
  • Change an agent's tools any time; other agents aren't affected

Workflows choose the tools for you: they add an app with just the tools their steps use. See workflows →

Built to be trusted

You stay in charge of what agents can do

Only the tools you choose

Connecting an app doesn't give any agent anything. Each agent gets the tools you pick for it, and no more.

Permissions come first

Every tool has a rule. Ones that send, publish, pay or delete ask you first, and you can tighten or loosen any of them per agent.

Your keys stay yours

Sign-ins and keys are stored in your workspace's settings, never shown again once saved, and only reach the app they belong to. Disconnecting an app removes its sign-in.

The app's own server

Each app in the catalog is the one the company itself publishes, so its tools are the ones it maintains.

Beyond apps

Abilities, for everything else

Not every app has an MCP server, and not everything an agent does is an app. Abilities fill the gap: each adds tools, a skill on using them well, and a permission for every tool, to any agent in a few clicks.

Official abilities

For apps without their own MCP server. Built and published by LoopEngine, under @loopengine-co on npm, so you know who wrote the code your agents run.

  • Free and open source
  • Search them right from your workspace
  • Upgrade when a new version comes out

Private abilities

For your own systems: your order API, your internal tools. Only your workspace sees them.

  • Connect your GitHub organization or private npm registry once, in Settings
  • Or upload one from your computer as a .zip, .tgz or folder
  • Installed into your workspace once, then added to any agent

Need something that isn't here yet?

Connect your own company's MCP server as an app, or build an ability for your own systems: a small package of tool files, a skill and its permission rules. Only your workspace sees it.
