## Description

Updates the value of an existing metafield on a Shopify resource (product, customer, order, etc.) via the `metafieldsSet` mutation. Use this to change custom data stored on a record you've already identified. Select the owner resource and record, then the specific metafield to update, and provide the new value. This action resolves the selected metafield and reuses its existing `namespace`, `key`, and `type` — only the value is changed, and the metafield must already exist. The value must be a string serialized to the metafield's `type` — for example `10` for `number_integer`, `{"color":"red"}` for `json`, or `2026-08-12` for `date`. To discover a resource's metafields first, use a list/get metafields action. [See the documentation](https://shopify.dev/docs/api/admin-graphql/latest/mutations/metafieldsSet)

## Props

| Prop | Type | Required | Description |

  clientId: process.env.PIPEDREAM_CLIENT_ID!,
  clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
  projectEnvironment: "production",
})

const accessToken = await pd.rawAccessToken

const transport = new StreamableHTTPClientTransport(
  new URL("https://remote.mcp.pipedream.net/v3"),

    },
  },
)

const mcp = new Client({ name: "my-agent", version: "1.0.0" })
await mcp.connect(transport)

const { tools } = await mcp.listTools()

// listTools() hands your model this tool's input schema, so it can
// fill the arguments itself:
const result = await mcp.callTool({
  name: "shopify-update-metafield",
  arguments: {
    ownerResource: "Resource Type",
  },
})
