Frequently asked questions
What is the accuracy of MailerCheck verification?
MailerCheck uses advanced multi-layer checks including syntax, DNS, and SMTP handshake to provide highly accurate results categorized into valid, risky, and invalid.
Can I verify large lists of emails?
Yes, use the create_verification_batch tool to upload a JSON array of email addresses. You can then monitor the progress and retrieve results once completed.
How do I check my remaining credits?
Use the get_account_info tool to retrieve your profile details and the current balance of verification credits in your account.
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.
MCP tools not available
Ensure you are in Agent mode in Copilot Chat. MCP tools only appear in Agent mode.
