MCP
One MCP session, both toolsets
One session gives your product or agent every Linear (API key) and Slack tool at once — connect once, list tools, and call them like any single-app session.
// accessToken: mint a short-lived token with the Connect SDK — see the MCP guide
const transport = new StreamableHTTPClientTransport(
new URL("https://remote.mcp.pipedream.net/v3"),
{
requestInit: {
headers: {
Authorization: `Bearer ${accessToken}`,
"x-pd-project-id": "{project_id}",
"x-pd-environment": "production",
"x-pd-external-user-id": "{external_user_id}", // any stable ID for this user in your system
"x-pd-app-slug": "linear_app,slack_v2",
},
},
},
)
const mcp = new Client({ name: "my-agent", version: "1.0.0" })
await mcp.connect(transport)
const { tools } = await mcp.listTools()
// One list, both toolsets: Linear (API key) and Slack tools arrive
// together, each keyed by its own app's slug.
// e.g. run Create Comment:
const result = await mcp.callTool({
name: "linear_app-create-comment",
arguments: {
teamId: "Team",
issueId: "Issue",
},
})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 externalUserId = "{external_user_id}" // any stable ID for this user in your system
const [linearAppTools, slackV2Tools] =
await Promise.all([
pd.components.list({ app: "linear_app" }),
pd.components.list({ app: "slack_v2" }),
])
// One external user owns both connected accounts, so either app's tools
// run on their behalf with the same externalUserId.curl "https://api.pipedream.com/v1/connect/{project_id}/components?app=linear_app" \

curl "https://api.pipedream.com/v1/connect/{project_id}/components?app=slack_v2" \

# Connect both accounts to the same external_user_id, then
# configure and invoke either app's tools on that user's behalf.ARCHITECTURE
One user, two connected accounts
Your user connects each account once, under whatever ID they already have in your product. The two stay independent — either can be revoked on its own — and your code reaches both through that one user.

Send Message to Channel
actionSend a message to a public or private channel. Legacy, channel-only variant — prefer Post Message for new integrations: it covers channels, users, and groups from a single tool, and also supports threaded replies and unfurl settings. Use this tool only if a workflow specifically needs to target a channel exclusively, without the user/group support Post Message offers. See the documentationWritev0.2.4 -
Add Emoji Reaction
actionAdd an emoji reaction to a message. See the documentationWritev0.0.28 -
Add Reaction
actionAdd an emoji reaction to a message. Accepts a channel ID (preferred — resolves instantly) or channel name (resolved by scanning up to 5 pages, ~5,000 channels, of the workspace's channel list — a name beyond that bound will not be found). Use Get Channel History or Search to find the message timestamp. Emoji name should be without colons (e.g.thumbsup,fire,heart). See the documentationWritev0.0.8 -
Archive Channel
