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
bangerathttps://api.bangermail.com/mcp(Streamable HTTP, OAuth 2.1 with PKCE and dynamic client registration). Declared in.mcp.json. The registry descriptor isserver.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.
