Common questions

Is Banger safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.1) reached the registry 30 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Banger plugin

All your company email, operated by agents and reviewed by you.

This one directory is the Banger plugin for every agent host that reads the open plugin layout: Claude Code and Claude Cowork (.claude-plugin/), Grok Build / Grok Bot (.grok-plugin/), ChatGPT / Codex (.codex-plugin/), and Cursor (.cursor-plugin/). Each host reads its own manifest; they all share the same skill and the same hosted MCP server. Any other MCP client connects to the same server; see llms-install.md.

What it ships

MCP server banger at https://api.bangermail.com/mcp (Streamable HTTP, OAuth 2.1 with PKCE and dynamic client registration). Declared in .mcp.json. The registry descriptor is server.json (com.bangermail/banger).
Skill operate-company-email: how to onboard a workspace, configure a company domain safely, turn business context into a reviewable email growth plan, and operate Mailboxes, Journeys, Broadcast, Product email, Approvals, and Logs with evidence.

No hooks, no local processes, no shell commands. Nothing runs on your machine; the plugin only points your agent at the hosted server and teaches it how to use it.

Install

Claude Code:

claude plugin marketplace add bangermail/banger-plugin

claude plugin install banger@banger

Grok Build / Grok Bot:

grok plugin install bangermail/banger-plugin --trust

Codex: install Banger from the Codex plugin directory, or add the server directly:

codex mcp add banger --url https://api.bangermail.com/mcp

codex mcp login banger

Cursor: install Banger from the Cursor Marketplace.

Cline, Docker MCP Toolkit, OpenClaw, Hermes, and any other MCP client: add the remote server https://api.bangermail.com/mcp (Streamable HTTP, OAuth). Step by step: llms-install.md and https://bangermail.com/banger-mcp/.

Claude Cowork and ChatGPT install Banger from their plugin directories once it is listed there.

On first use the host opens Banger's authorization page. Sign in, choose the workspace, and approve the scope set shown. Banger never asks for credentials in chat.

Network and data

The only endpoint the plugin talks to is https://api.bangermail.com (MCP over HTTPS plus its OAuth endpoints under /oauth/* and /.well-known/*).
Authentication is a per-workspace OAuth grant issued to your agent. Revoke it from the Banger app at any time.
Governed actions (sending, launching a Broadcast, activating a Journey) honor the workspace approval policy; the agent cannot bypass a required approval.

License

Proprietary; see LICENSE. Copyright BangerMail Inc. Use of the hosted service is governed by the Banger Terms of Service.
