Mail

What mail MCP server does

The mail MCP server provides access to email and calendar services through standard mailbox protocols. Its stated scope covers email over IMAP and calendars over CalDAV, allowing it to work with a range of hosted mailbox providers rather than targeting only one vendor.

The listed provider examples include OVH, Gandi, iCloud, Zoho, and Fastmail. The description also says that other providers are supported, but it does not define the complete provider list or identify provider-specific differences.

For an AI workflow, the relevant capability is mailbox-based access to email and calendar information. The available material does not specify whether the server supports reading, searching, sending, creating, updating, or deleting individual records, so those operations should not be assumed without checking the project’s current documentation.

How it works

The mail MCP server uses IMAP for email and CalDAV for calendar access, according to the project description. These protocols are the key compatibility criterion: a mailbox that exposes the required service through IMAP or CalDAV may fit the stated use case.

This makes the mail MCP server a candidate for workflows that need one MCP connection across different hosted mailbox providers. The source does not provide transport details, tool names, authentication flow, synchronization behavior, or examples of MCP client configuration.

Limitations and notes

The available source is limited to a short product description, and the repository README is unavailable. As a result, installation commands, required credentials, environment variables, supported MCP transports, exact tool names, permission requirements, and client compatibility cannot be verified here.

Provider support is described broadly, with OVH, Gandi, iCloud, Zoho, and Fastmail named as examples. That statement does not establish that every account configuration from those providers will work, nor does it document provider-specific setup steps.

Before deploying the mail MCP server, verify the current documentation for the required IMAP and CalDAV endpoints, authentication settings, supported operations, and data-handling behavior. The available material supports identifying the server as an email-and-calendar bridge for compatible mailboxes, but not a more detailed operational specification.
