Banger plugin for Claude, Grok, and Codex: company email operated by agents, reviewed by you.

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 theopen 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 ownmanifest; they all share the same skill and the same hosted MCP server. Anyother MCP client connects to the same server; seellms-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 isserver.json (com.bangermail/banger).
  • Skill operate-company-email: how to onboard a workspace, configure acompany domain safely, turn business context into a reviewable email growthplan, 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 touse it.

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

On first use the host opens Banger's authorization page. Sign in, choose theworkspace, and approve the scope set shown. Banger never asks for credentialsin 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 itfrom the Banger app at any time.
  • Governed actions (sending, launching a Broadcast, activating a Journey) honorthe workspace approval policy; the agent cannot bypass a required approval.
