## Authentication

Two options — no copy-paste needed for the first:

1. **Browser login.** Start the server with no key and run the `login` tool.
   It opens the MisarMail consent screen, you review the requested
   permissions, and the key is delivered straight back and saved to
   `~/.misarmail/config.json`.
2. **API key.** Create one at https://mail.misar.io/developers and set `MISARMAIL_API_KEY`.

Self-hosted instances: set `MISARMAIL_BASE_URL`.

## Agent skills

Bundled in [`skills/`](./skills) — guidance an agent loads when a task matches.

| Skill | Use when |
| --- | --- |
| `ab-test-campaign` | Design and run an A/B test on a MisarMail campaign — subject line, content, sender name, or send time. Use for "A/B test", "split test", "which subject works better", or testing email variants. |
| `audit-deliverability` | Diagnose why MisarMail emails land in spam or bounce, and produce a prioritized fix list. Use for "emails going to spam", "not being delivered", "low open rate", "domain reputation", DMARC/SPF/DKIM, or blocklist questions. |
| `build-email-automation` | Design and build a MisarMail automation workflow — welcome series, drip sequence, re-engagement, or onboarding. Use for "automate", "drip", "welcome series", "sequence", or trigger-based email. |
| `clean-contact-list` | Audit and clean a MisarMail contact list — bounced, complained, and unengaged contacts. Use for list hygiene, re-engagement, suppression, or "why is my open rate falling". |
| `email-performance-report` | Produce a MisarMail performance report — opens, clicks, deliverability, revenue attribution. Use for "how are my emails doing", weekly/monthly reports, or campaign performance analysis. |
| `run-email-campaign` | Create, review, and send a bulk email campaign in MisarMail. Use when the user wants to email a list, newsletter, segment, or announcement to many recipients. |
| `send-transactional-email` | Send a one-off or transactional email through MisarMail. Use when the user asks to send, draft-and-send, or reply to an email — including receipts, notifications, welcome messages, and personal outreach. |
| `setup-sending-domain` | Add and verify a custom sending domain in MisarMail, including SPF, DKIM, DMARC, and inbound routing. Use for "send from my own domain", DNS setup, domain verification, or inbound email. |

## Safety

Destructive and irreversible actions are annotated (`destructiveHint`) so
clients can prompt before running them. The skills instruct agents to confirm
before anything that sends mail, publishes content, or is otherwise visible to
other people.

Discovery (`initialize`, `tools/list`, `prompts/list`, `resources/list`)
never requires credentials, so registries can index the server without one.
Every action does.
