Banger — Claude Code MCP server: what it does, how to install
Runs company email through AI agents while keeping human approvals in place. Useful for managing domains, broadcasts, and automated email flows.
claude mcp add --transport http banger https://api.bangermail.com/mcpWhat Banger does
Banger connects your assistant to company email tools without running local binaries. The tool points to a hosted remote endpoint at https://api.bangermail.com/mcp over Streamable HTTP. It teaches agents to handle mailboxes, transactional messages, and marketing campaigns.
Authentication relies on OAuth 2.1 with PKCE. On the first run, your agent opens a browser window to grant workspace access. Credentials never touch the chat log. Governed actions enforce safety: the agent cannot trigger broadcasts or send batches without required human approval.
What it helps with
- configure company domains for outgoing mail
- prepare and review marketing broadcasts
- inspect delivery logs and message histories
- manage automated email journeys under approval rules
Example prompts for the agent
- Check our domain setup and list all active mailboxes
- Draft a new customer broadcast and submit it for review
- Inspect recent delivery logs to find failed emails
