Overview

AI-generated overview

Lets an assistant create disposable test mailboxes on a real domain and send, receive and assert on real email.

What you can do
This remote server provides disposable test mailboxes on a real domain. According to the registry description, it lets an assistant send email, receive email and assert on real email, which supports automated email testing. No individual tools are listed in the manifest.
When to use it
Useful when an assistant needs to exercise email flows end to end, such as sign-up confirmations or transactional messages, against real mailboxes rather than mocks.
Requirements
A remote MCP endpoint reached over streamable HTTP; no local package or runtime is needed. Authentication is required via OAuth, and an org-scoped API key is supplied in the X-API-Key header. Network access to the remote endpoint is required.
Before you install
The X-API-Key header carries an org-scoped secret; keep it out of logs and shared configuration. The server can send real email from a real domain and read received messages, so test content and recipients should be chosen deliberately.

Installation

In SourceWeft

  1. Open fixture.email — Email Testing for Agents in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/email.fixture%2Femail-testing/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.
