🔍 Glama
Plug real inbox-placement testing into Claude Desktop, Cursor, Windsurf, Cline,
or any other MCP-compatible AI client. The server wraps the Inbox Check REST
API and exposes 5 tools your agent can call directly — create a test, send
your email to the returned seed addresses, and read back per-provider
placement (Inbox / Spam / Promotions / Updates), authentication results
(SPF, DKIM, DMARC), headers, and screenshots.
Why use this?
- **9 real provider mailboxes** — Gmail, Outlook, Yahoo, iCloud, AOL, GMX,
T-Online, Mail.ru, Yandex. Not simulations: actual IMAP-backed seed
accounts, actual filter verdicts.
- **Authentication verification** — SPF, DKIM, DMARC alignment reported
per delivery, parsed from Authentication-Results headers.
- **Folder detection** — Inbox, Spam, Promotions, Updates, Social,
Forums, Category-specific tabs where providers expose them.
- **Screenshots** — rendered inbox/spam list view for Gmail, Outlook
and others, so the agent can show the user what the recipient sees.
- **No flaky scraping** — the service runs its own seed mailboxes; your
agent only talks to a stable REST API.
- **Built for AI agents** — strict JSON schema via Zod, deterministic
tool names, cursor pagination, idempotent keys.
