Can Multiple App Slugs be Passed When Connecting to MCP Servers Without Enabling Full Discovery?

Is there a way to pass in multiple app slugs when connecting to the MCP servers? Don’t want to enable full discovery, just filter the set of apps/tools to a specific subset. Can create a connection per app if needed, but was hoping there’s a way to pass a list of apps slugs

i do it like this:

"use server";
import { experimental_createMCPClient as createMCPClient, Message } from "ai";

import { IntegrationType } from "@prisma/client";

import { pipedreamBEClient } from "@jenius/core/services/integrations/pipedreamBEClient";
import { IntegrationsService } from "@jenius/core/services/integrations";

export const getMCPToolsForTask = async (
  orgId: string,
  userId: string,
  messages: Message[]
) => {
  const lastMessage = messages[messages.length - 1];

  if (!lastMessage) {
    throw new Error("No last message found");
  }

  const connectedIntegrations =
    await IntegrationsService.getChatAccessibleIntegrations({
      organizationId: orgId,
      userId,
    });

  const accessToken = await pipedreamBEClient.rawAccessToken;

  const mcpClients = await Promise.all(
    connectedIntegrations.map(
      ({ integration: { providerSlug, type }, connectedById }) => {
        const externalUserId =
          type === IntegrationType.personal ? connectedById : orgId;

        return createMCPClient({
          transport: {
            type: "sse",
            url: `https://remote.mcp.pipedream.net/${externalUserId}/${providerSlug}`,
            headers: {
              Authorization: `Bearer ${accessToken}`,
              "x-pd-project-id": process.env.PIPEDREAM_PROJECT_ID!,
              "x-pd-environment": process.env.PIPEDREAM_ENV!,
            },
          },
        });
      }
    )
  );

  return {
    ...Object.assign(
      {},
      ...(await Promise.all(mcpClients.map((client) => client.tools())))
    ),
  };
};

I believe you can pass multiple app slugs, it may just be undocumented — can you try just passing a comma separate list of app slugs in the x-pd-app-slug header or app query param?

Thanks – yes, turns out comma separated list of apps slugs works :slightly_smiling_face:
