MCP servers for email in Claude Code

1,084 MCP servers for email in the catalog list Claude Code as a supported host. These are the 15 that rank highest, ordered by adoption, freshness and documentation. Inbox Zero, Kody and Agent-Native Mail lead the list. 15 of them have an install command written for Claude Code; the rest use the generic setup below. Claude Code reads them from ~/.claude.json (just you), or .mcp.json in the project when you add --scope project. Give an MCP server only the access it needs, and read its repository before you connect it to your data. Every listing links to its source and shows a freshness grade.

How to install in Claude Code

claude mcp add <name> -- npx -y <package>
claude mcp add --transport http <name> <https://server-url>

Where it goes: ~/.claude.json (just you), or .mcp.json in the project when you add --scope project.

Put -- between the name and the server command so the command's own flags are not read as Claude's. --env takes several KEY=value pairs, so another option has to sit between the last --env and the name (the CLI otherwise reads the name as a pair). --scope user makes the server available in every project; the default scope (local) keeps it to you in this project. Run /mcp inside Claude Code, or claude mcp list, to check it is connected.

Each listing page has the exact command for that listing.
