## What it 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.
