Can the AI send emails dynamically using my existing templates?

Yes. Using `send_with_template`, you merely tell the AI the template ID and the JSON parameters (Template Model). It perfectly injects the data into your Postmark layouts.

Is it possible to debug a complex email bounce natively inside Claude?

Absolutely. First command `list_bounces` to find failing message UUIDs. Then ask the agent to run `get_bounce_logs` on that UUID—it will interpret the pure SMTP error code for you naturally.

Which Postmark token should I use?

This MCP server uses the Postmark Server Token. Each Server in Postmark functions as an isolated environment (e.g. Production Server vs Staging Server).

About Postmark MCP Server

Connect your Postmark server safely to any AI agent, granting it the ability to dispatch transactional emails, debug delivery failures, and inspect mailing architectures directly via conversational prompts.

GitHub Copilot Agent mode brings Postmark data directly into your VS Code workflow. With a project-scoped config, the entire team shares access to 10 tools. Copilot queries live data, generates typed code, and writes tests from actual API responses, all without leaving the editor.

What you can do

Send Emails & Templates — Command the AI to dispatch text-based emails or trigger rich HTML messages using pre-existing Postmark templates (send_with_template)
Inspect Bounces & Logs — Ask why an email failed. The AI can pull exact SMTP traces (get_bounce_logs) to explain spam rejections or DNS timeouts
Monitor Delivery Stats — Retrieve precise operational health data, mapping open rates and physical bytes sent across massive volumes
Manage Configurations & Templates — List active webhooks spanning your routing, edit server names, or safely clean up legacy template layouts

The Postmark MCP Server exposes 10 tools through the Vinkius. Connect it to VS Code Copilot in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

Postmark + VS Code Copilot FAQ

Common questions about integrating Postmark 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.
