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.
