Where do I find my NeverBounce API Key?

Log in to your NeverBounce dashboard and navigate to the API section to create or copy your 'Secret Key'.

What do the different result statuses mean?

'Valid' means the email is safe to send. 'Invalid' will bounce. 'Disposable' are temporary addresses, and 'Catchall' means the domain accepts all mail, making deliverability uncertain.

How do I start a bulk verification job?

First, use `create_job_from_url` or `create_job_from_input`. Then, call `parse_job` followed by `start_job` to begin the verification process.

NeverBounce + VS Code Copilot FAQ

Common questions about integrating NeverBounce 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.
