• Start from scratch, on the platform
• Go to "Create MCP Configs" tab, with name mcp-config-manual
• Add Toolkit:
  • "Gmail", with Auth Config name "mcp-gmail-manual-1"
    • Add tools: "Fetch Emails", "Get Contacts", "Get Gmail attachment"
  • "Github", with Auth Config name "mcp-github-manual-1"
    • Add tools: "List pull requests"
• Hit "Create MCP"
• Go to "Auth Configs" tab
• Select "mcp-gmail-manual-1"
  • Follow the OAuth flow to connect your Gmail account
  • Hit "Connect Account" with User ID "[email protected]"
  • Log in with the Gmail account "[email protected]"
• Select "mcp-github-manual-1"
  • Follow the OAuth flow to connect your Github account
  • Hit "Connect Account" with User ID "id-jkomyno"
  • Log in with the Github account "jkomyno"

Attempting to fetch emails using the SDK with this configuration

const mcpConfig = await composio.mcp.getByName('mcp-config-manual')

// 3. Retrieve the MCP server instance for the connected accounts
const urls = await composio.mcp.getServer(mcpConfig.id, 'mcp-manual-1');

// @ts-ignore
const url = urls[0].url;

results in the following error:

✅ Calling tool GMAIL_FETCH_EMAILS
2620 |       const connectedAccounts = await this.client.connectedAccounts.list({
2621 |         user_ids: [userId],
2622 |         toolkit_slugs: [tool.toolkit.slug]
2623 |       });
2624 |       if (connectedAccounts.items.length === 0) {
2625 |         throw new Error("No connected accounts found");
                         ^

• Go to "MCP Configs" tab
• Create MCP Server with user ID "mcp-manual-1"
• Connect to mcp-gmail-manual-1
• Connect to mcp-github-manual-1

The resulting output is something like:

npx @composio/mcp@latest setup \
  "https://apollo.composio.dev/v3/mcp/237c34d4-7e54-4e57-aee4-55b29cc1679d/mcp?user_id=mcp-manual-1" \
  "mcp-config-manual" \
  --client cursor

This still results in the same error when running the code above:

✅ Calling tool GMAIL_FETCH_EMAILS
2620 |       const connectedAccounts = await this.client.connectedAccounts.list({
2621 |         user_ids: [userId],
2622 |         toolkit_slugs: [tool.toolkit.slug]
2623 |       });
2624 |       if (connectedAccounts.items.length === 0) {
2625 |         throw new Error("No connected accounts found");
                         ^
