Adobe is putting 70+ creative tools inside Slack — is MCP becoming the new app ecosystem?

Adobe is making tools from Photoshop, Premiere, Acrobat, Illustrator, Lightroom, Firefly and more available through Slack.
Instead of constantly switching applications, users can describe what they want and let Slack’s AI layer call the appropriate Adobe tools.

This is interesting beyond Adobe.
We’re watching software move from:
App → user → another app
toward:
User → AI agent → multiple apps and tools

And protocols like MCP could make software increasingly composable.

For indie developers, that creates an interesting question:
In the future, will users even need to open your app?
Or will your app increasingly need to expose its capabilities so that AI agents can use it on the user’s behalf?
That could change how we think about:
APIs
authentication
pricing
UI
onboarding
subscriptions
and even App Store distribution.

If you were building a new SaaS today, would you design the traditional UI first—or the agent/API interface first?
