Slack ACTION
Find User by ID
Find a user by their ID — including a specific user you already have the Slack ID for, whether or not it's your own. Returns user profile information including name, email (requires
users:read.email scope), timezone, and status. If you only have an email address, use Find User by Email instead. See the documentation- Action

IMPLEMENTATION
Call this tool
Connect a user's Slack account once, then configure and run Find User by ID from your backend or agent.
import { PipedreamClient } from "@pipedream/sdk"
const pd = new PipedreamClient({
projectId: process.env.PIPEDREAM_PROJECT_ID!,
clientId: process.env.PIPEDREAM_CLIENT_ID!,
clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
projectEnvironment: "production",
})
const result = await pd.actions.run({
id: "slack_v2-find-user-by-id",
externalUserId: "{external_user_id}", // any stable ID for this user in your system
configuredProps: {
slack_v2: { authProvisionId: "apn_xxxxxxx" },
user: "User",
includeLocale: true,
},
})

await mcp.connect(transport)

// fill the arguments itself:
