Give your AI agent an inbox and a send button
A hosted MCP server with 60+ tools, so Claude, Cursor, Codex and any MCP client can send email, manage contacts, run campaigns and automations, and check deliverability — in plain language.
Setup in under a minute
One MCP server, every email operation
Hosted and remote — nothing to install or run. Connect once with a scoped API key and your agent gets typed tools for sending, contacts, campaigns, automations, domains and analytics.
Claude Code
Anthropic’s agentic coding tool for the terminal.
- 1
Add the server
Run this in your terminal. It registers MailCraft for your user; use --scope project to share it with a repository instead.
terminalclaude mcp add --transport http mailcraft https://mcp.mailcraft.host \ --header "Authorization: Bearer sk_live_your_api_key"Replace sk_live_your_api_key with your key. The agent only gets the tools that key's scopes allow.
- 2
Verify the connection
Start Claude Code and run /mcp — mailcraft should be listed as connected. Then ask it something:
claudeList all my MailCraft domains
Prefer signing in? Run the same command without --header, then choose mailcraft in /mcp and authenticate in your browser.
Scoped keys
Agents only see the tools your key’s scopes allow — a send-only key can’t touch contacts.
Clear guardrails
Sending and destructive tools are marked, and plan limits or blocked actions come back as plain-English errors.
Lean context
Core tools are listed up front; the rest load on demand through tool search, so context stays small.
60+ tools
Every part of MailCraft, exposed as a tool
One tool per API endpoint, with the same validation and the same responses — so an agent can do anything you can.
Sending
Send transactional email, validate addresses and check delivery status.
Contacts
Create and update contacts, subscriptions, custom properties and lists.
Segments
Build segments from properties and list membership, with live counts.
Templates
Create, update and organise versioned templates in folders.
Campaigns
Draft campaigns for a list or segment, send them and read the stats.
Automations
Build sequences, activate and pause them, and enroll contacts.
Domains & senders
Add domains, check DNS verification and manage sender identities.
Analytics
Query daily sending metrics and bounce and complaint reputation.
Just ask
No endpoints to remember. Your agent finds the right tools and looks up the ids it needs — and the server tells it to confirm with you before sending email or deleting anything.
