Can I use templates with the send_transactional_email tool?

Yes, you can specify a `template_id` within the `email_json` body to use pre-defined designs created in your MailerSend account.

How do I filter activity for a specific event like 'opened'?

Use the `list_domain_activity` tool and provide the `params` string with the desired event types (e.g., `event[]=opened`).

Is there a limit to bulk email requests?

The `send_bulk_transactional_emails` tool supports up to 500 email objects per single request as per MailerSend API limits.

MailerSend + VS Code Copilot FAQ

Common questions about integrating MailerSend MCP Server with VS Code Copilot.

Which VS Code version supports MCP?

MCP support requires VS Code 1.99 or later with the GitHub Copilot extension. Ensure both are updated to the latest version. Older versions of Copilot may not expose the Agent mode toggle.

How do I switch to Agent mode?

Open the Copilot Chat panel and look for two mode options: "Ask" and "Agent". Click "Agent" to enable autonomous tool calling. In Ask mode, Copilot provides conversational answers but cannot invoke MCP tools.

Can I restrict which MCP tools Copilot can access?

Yes. VS Code shows a tool consent dialog before any MCP tool is invoked for the first time. You can also configure tool access policies at the organization level through GitHub Copilot settings.

Does MCP work in VS Code Remote or Codespaces?

Yes. MCP servers configured via .vscode/mcp.json work in Remote SSH, WSL, and GitHub Codespaces environments. The MCP connection is established from the remote host, so ensure the server URL is accessible from that environment.
