What is the 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.
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
How it works
- Subscribe to this server
- Enter your Postmark Server Token
- Start managing outbound communications natively in Claude, Cursor, or your preferred MCP client
Forget logging into dashboards to copy-paste trace IDs. Ask the model to 'find the latest bounce logs' and watch it dissect the 5xx errors for you.
Who is this for?
- Backend Engineers — quickly check explicit webhook constraints or edit server settings on the fly
- Support Teams — investigate exact reasons for "hard bounces" mapping physical UUIDs when users complain about missing emails
- QA Testers — effortlessly trigger test templates and read precise delivery confirmation metrics

Frequently asked questions
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).
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.
