Postmark

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

  1. Subscribe to this server
  2. Enter your Postmark Server Token
  3. 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

Why Cursor?

Cursor's Agent mode turns Postmark into an in-editor superpower. Ask Cursor to generate code using live data from Postmark and it fetches, processes, and writes. all in a single agentic loop. 10 tools appear alongside file editing and terminal access, creating a unified development environment grounded in real-time information.

  • Agent mode turns Cursor into an autonomous coding assistant that can read files, run commands, and call MCP tools without switching context

  • Cursor's Composer feature can generate entire files using real-time data fetched through MCP. no copy-pasting from external dashboards

  • MCP tools appear alongside built-in tools like file reading and terminal access, creating a unified agentic environment

  • VS Code extension compatibility means your existing workflow, keybindings, and extensions all work alongside MCP tools

FAQ

Frequently asked questions

01

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.

02

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.

03

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).

04

What is Agent mode and why does it matter for MCP?

Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.

05

Where does Cursor store MCP configuration?

Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.

06

Can Cursor use MCP tools in inline edits?

No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.

07

How do I verify MCP tools are loaded?

Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.

08

Tools not appearing in Cursor

Ensure you are in Agent mode (not Ask mode). MCP tools only work in Agent mode.

09

Server shows as disconnected

Check Settings → Features → MCP and verify the server status. Try clicking the refresh button.
