# Skills vs MCP

Here's an outline of these buzzwords.

<Columns cols={2}>
  <Card title="MCP">
    A standard to fetch data, often gated with sign in/API keys, eg token balances
  </Card>

  <Card title="Skills">
    What to do with the data, eg step by step instructions to build a token portofolio page, formatting ETH units.
  </Card>
</Columns>

Often they would be combined, when working with a prompt like

```
Analyse this address holding $HYPE
```

Using Skills and MCP in tandem, a workflow would look like

1. Check Skills for instructions to analyse an address
2. Skills outlines steps to get a user's txns, isolate addresses interacted with, and fetch labels for these addresses
3. Model connects to an MCP to retrieve the user txns and labels
4. Model observes that tokens are sent to addresses labelled "Bybit 17", and reasons this as selling
5. Model presents a summary to the user
