Fluxmail MCP Server

Fluxmail is self-hosted email infrastructure for agents and apps. It connects to Gmail, Microsoft 365, Outlook.com, and IMAP/SMTP mailboxes. Agents use MCP, apps and backend workflows use the versioned REST API, and operators use the CLI to connect mailboxes, manage access, and run the service. It runs locally over stdio via the published package.

People connecting email tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

repo age created 2026-07-09 - young repo, little track record yet

license no standard license detected - usage rights unclear; check the repo before commercial use

npm package fluxmail - unscoped; check the name against the project README before installing

registry namespace io.github.churichard is GitHub-verified and matches the repo owner
