[FEATURE] Add support for MCP and/or Skills

[Liozhang]

Is your feature request related to a problem? Please describe.
I'm currently building a Dash app and realized it would be really useful if AI agents could interact with it directly—like querying data or triggering actions. Right now, there's no standardized way to expose Dash functionality as tools that an AI assistant can discover and use, which makes integrating AI-driven features more custom and harder to reuse.

Describe the solution you'd like
I'd love to see Dash support something like Skills (tools that AI agents can call) — ideally with a standard protocol like MCP, but the key is making it easy to define and expose app capabilities. If Dash had a built-in way to turn callbacks or Python functions into callable skills, it would make building AI‑enabled apps so much smoother.

Describe alternatives you've considered
I could build REST endpoints manually, but that lacks discoverability and a consistent schema for tool descriptions. Using an external agent framework would also add complexity without tight integration with Dash's state and callbacks.

Additional context
I think supporting Skills (and optionally MCP) would really help developers like me create smarter Dash apps that can work with AI assistants. Curious if this is on your radar.

@Liozhang this is actually something we are actively working on and plan to have a release candidate for within the next month!

Other initiatives that might be interesting since you're thinking about AI agents the same way we are:

1. We have a Desktop product called Plotly Studio designed to help build Dash apps.
2. We're working on an agentic chat client Dash component so viewers can ask quick follow-ups about their data.
3. We're starting to explore building out an MCP aggregation service in Plotly Cloud - so users don't need to register each individual Dash app.
