Overview

AI-generated overview

Hosted Banger MCP server that lets an assistant operate a company's email — mailboxes, journeys, broadcasts and approvals — with human review.

What you can do
  • Onboard a workspace and configure a company domain safely
  • Turn business context into a reviewable email growth plan
  • Operate mailboxes, journeys, broadcasts and product email
  • Review approvals and inspect logs with supporting evidence
When to use it
Useful when a team wants an agent to draft, plan and run company email marketing inside Banger while keeping human approval on sending, broadcasts and journey activation.
Requirements
Remote Streamable HTTP endpoint at api.bangermail.com with OAuth 2.1 (PKCE, dynamic client registration); no local process or package. A Banger account and workspace are needed, and the host opens an authorization page on first use to sign in, pick a workspace and approve scopes.
Before you install
The OAuth grant is per workspace and gives the agent access to company email operations; revoke it in the Banger app when no longer needed. Governed actions such as sending, launching a broadcast or activating a journey follow the workspace approval policy, so review that policy before use. Email content and workspace data go to the Banger service.

Installation

In SourceWeft

  1. Open Banger 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/com.bangermail%2Fbanger/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.

README

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:

bash
claude plugin marketplace add bangermail/banger-pluginclaude plugin install banger@banger

Grok Build / Grok Bot:

bash
grok plugin install bangermail/banger-plugin --trust

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

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