MCP

Give your agent Bot for Slack tools

Every Bot for Slack action is exposed as an MCP tool on Pipedream's remote server. Point a client at it with your end user's ID and Connect resolves that user's Bot for Slack account for each tool call — you store no tokens.

Pipedream Connect

// 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"),

  },

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

API PROXY

Call the Bot for Slack API directly

For an endpoint with no pre-built tool, the Connect proxy forwards your request to the Bot for Slack API with the connected user's credentials attached. You store no tokens and write no refresh logic.

Pipedream Connect

const resp = await pd.proxy.get({
  externalUserId: "{external_user_id}", // any stable ID for this user in your system
  accountId: "apn_xxxxxxx",
  url: "https://slack.com/api/auth.test",
})

// Any allowed Bot for Slack endpoint works here. Pipedream attaches the
// connected account's credentials to the outgoing request.

# The path segment is the target URL, URL-safe base64 encoded:
# https://slack.com/api/auth.test

curl "https://api.pipedream.com/v1/connect/{project_id}/proxy/aHR0cHM6Ly9zbGFjay5jb20vYXBpL2F1dGgudGVzdA?external_user_id={external_user_id}&account_id=apn_xxxxxxx" \
  -H "Authorization: Bearer {access_token}" \
  -H "x-pd-environment: production"

SDK

Run Bot for Slack actions from your backend

Connect a user's Bot for Slack account once, then run Add Emoji Reaction on their behalf from your own code — TypeScript, Python, or plain HTTP.

Pipedream Connect

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_bot-add-emoji-reaction",
  externalUserId: "{external_user_id}", // any stable ID for this user in your system
  configuredProps: {
    slack_bot: { authProvisionId: "apn_xxxxxxx" },
    conversation: "Channel",
    timestamp: "Message Timestamp",
  },
})

from pipedream import Pipedream

pd = Pipedream(
    client_id="{oauth_client_id}",
    client_secret="{oauth_client_secret}",
    project_id="{project_id}",
    project_environment="production",
)

result = pd.actions.run(
    id="slack_bot-add-emoji-reaction",
    external_user_id="{external_user_id}",  # any stable ID for this user in your system
    configured_props={
        "slack_bot": {"authProvisionId": "apn_xxxxxxx"},
        "conversation": "Channel",
        "timestamp": "Message Timestamp",
    },
)

curl -X POST https://api.pipedream.com/v1/connect/{project_id}/actions/run \
  -H "Content-Type: application/json" \
  -H "X-PD-Environment: production" \
  -H "Authorization: Bearer {access_token}" \
  -d '{

    }
  }'
