Each figure is the marketplace's own and is never added up across marketplaces. A marketplace that publishes no figure shows none: no number is not zero.

Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.

What each says it does

Resend

How to run each

Resend As a local MCP server: Docker image

Claude Code
claude mcp add --env "RESEND_API_KEY=<YOUR_RESEND_API_KEY>" --transport stdio resend -- docker run -i --rm -e RESEND_API_KEY mcp/resend

Requires: RESEND_API_KEY (secret)

mcp-mail As a local MCP server: npm package

Claude Code
claude mcp add --transport stdio mcp-mail -- npx -y @annseraf/mcp-mail stdio

Commands built only from what the marketplaces declare; the full set for every client is on each card.

Tools each declares

The marketplaces of mcp-mail publish no list of tools, so we do not compare tools.

Settings each asks for

Only Resend asks for

  • REPLY_TO_EMAIL_ADDRESSES
  • RESEND_API_KEY (secret)
  • SENDER_EMAIL_ADDRESS

Only mcp-mail asks for

  • ACCOUNTS_FILE
  • STDIO_PRESET

Settings as each marketplace publishes them. Asking for fewer is not better in itself.

Data comes from the Docker MCP Catalog (desktop.docker.com/mcp/catalog) and Docker Hub. Data comes from the Official MCP Registry (registry.modelcontextprotocol.io), CC0 1.0. Figures come from our own regular passes over the marketplaces, last read on . We publish no contact details for plugin publishers.
