Connect Email Spam Tester and your agent gets 4 tools, among them get_message_source, get_report, get_test_address. It answers at https://email-spam-tester.com/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 4 of 4 times since 17 September 2026; the last check, on 25 October 2026, succeeded.
Test an email before it goes out: a disposable address, 41 checks with RFC citations, a fix plan.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
get_message_source | The message exactly as it was received: headers, both bodies, source. Useful when a finding points at a header and the agent needs to see what it actually sent rather than what it believes it sent. Inputs: slug |
get_report | Read an existing report by its slug, without waiting. Inputs: slug |
get_test_address | Reserve a single-use address to send a draft message to. Returns the address and the URL its report will appear at. The address accepts exactly one message and expires after an hour. lang is the language the fix plan will be written in, as Inputs: lang |
wait_for_report | Wait until the message arrives and has been analysed, then summarise it. Blocks rather than returning "not ready yet": an agent told to poll writes a sleep loop and usually gives up before the analysis finishes. Inputs: slug, timeout_seconds |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://email-spam-tester.com/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
