Mcp Server
Let your coding agent send and receive email as markdown through MultiMail while you keep human oversight on outbound messages.
Overview
dev.multimail/mcp-server is an MCP server for the Build phase that lets agents send and receive MultiMail email as markdown with required API key auth and human send oversight.
What is this MCP server?
- stdio MCP package @multimail/mcp-server (v0.1.5) for local agent clients
- Send and receive email formatted as markdown for LLM-friendly parsing
- Human oversight path on sending—safer than fully autonomous mail blast
- Requires MULTIMAIL_API_KEY (mm_live_*); optional MULTIMAIL_MAILBOX_ID or per-tool mailbox_id
- list_mailboxes workflow when no default mailbox is configured
- Package version 0.1.5 (@multimail/mcp-server)
- Transport: stdio
- 2 documented environment variables (1 required secret API key, 1 optional mailbox default)
Community signal: 1 GitHub stars.
What problem does it solve?
Agents cannot safely read or act on email without a vetted integration, so builders either copy-paste threads or risk unsupervised auto-send.
Who is it for?
Indie builders automating inbox triage or agent-driven transactional email on a MultiMail mailbox.
Skip if: High-volume marketing email, teams needing full CRM pipelines, or environments that cannot store mm_live_* API secrets locally.
What do I get? / Deliverables
After install and MULTIMAIL_API_KEY setup, your agent can list mailboxes, work markdown threads, and propose sends under MultiMail’s oversight model.
- Working stdio MultiMail MCP server in your agent client
- Agent-accessible send/receive email flows on configured mailboxes
