One block, then ask.
Claude Code registers MCP servers from the command line. Scope a key in the dashboard, run the command, restart the session — the tools are just there.
Full setup guide →$ claude mcp add drin \
-e DRIN_API_KEY=drin_k_… \
-- npx -y @drin00/mcp
# restart the session — 54 tools appear.
# also works in the Claude desktop app via mcpServers.Paste one of these first.
Three real tasks, end to end — copy a prompt and watch it run the tools.
Create an inbox support@mydomain.com and a webhook to https://myapp.com/inbound, then simulate an inbound email and show me the parsed payload.
Send a test email from hello@mydomain.com to my address with subject "Drin wired up", then check whether it delivered and show me the event trail.
Draft a campaign to the NEWS topic announcing v2.0 — pull the highlights from the changelog — and route it to me for approval. Don't send anything yourself.
Asked about Claude Code.
Does this work in the desktop app too, or only Claude Code?+
Both. Claude Code adds it with the one-liner; the desktop app takes the same server in its mcpServers config. Any MCP client gets the identical 54 tools.
Is it safe to hand Claude my API key?+
Scope the key in the dashboard and start in the sandbox, where sends only reach verified recipients. Anything wide — a campaign, an automation going live — waits for a human reply regardless of what the agent wants. How approve-by-reply works →
What can Claude actually do with it?+
Everything the dashboard can: send and batch mail, create inboxes, read threads and reply in them, verify domains, manage templates, webhooks and suppressions, pull metrics, and draft campaigns.
Do I need the Claude Skills as well?+
No — the MCP server alone is enough. The skills add worked procedures (compose, triage an inbox, verify a domain, report metrics) so Claude follows the good path instead of improvising one.
Does this cost extra?+
No. MCP, the CLI and skills ship on every plan, including the free sandbox. Pricing →
