Frequently asked questions
Can I find all professional email addresses for a specific company?
Yes. Use search_domain_emails with a domain (e.g., 'stripe.com') or company name (e.g., 'Stripe') to retrieve all professional emails found for that organization. Each result includes the email, confidence score, position, and source URLs. Use get_domain_email_count to preview how many emails are available before using search credits.
Can I verify if an email address is valid before sending outreach?
Yes. The verify_email_address tool checks the validity and deliverability of any email address. It returns a status (deliverable, undeliverable, risky, unknown), confidence score, and details about the email server (MX records, SMTP check, accept-all detection). This prevents bounces and protects your sender reputation.
How does Hunter API authentication work?
Hunter uses an API Key passed as a query parameter (?api_key=YOUR_KEY) in all requests to api.hunter.io/v2. This differs from the typical Bearer token pattern. Your API key is available in the Hunter dashboard under Account > API. Free accounts include 25 searches and 50 verifications per month.
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.
