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/ — 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.
