Command Mail vs Email MCP
In-depth architectural comparison of the Command Mail and Email MCP MCP servers. Compare execution transports, security boundaries, tool capabilities, quality scores, and ready-to-paste client installation snippets for Claude, Cursor, Windsurf, and VS Code.
At a Glance & Executive Verdict
Command Mail
Communication · Remote HTTP/SSE
Quality: 50/100 (Good) | Auth: OAuth 2.0
Email MCP
Communication · Local stdio
Quality: 68/100 (Great) | Auth: other
Verdict Summary: Choose Command Mail if you need specialized Communication tools running via a hosted cloud SSE transport. Choose Email MCP if your workspace requires Communication integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.

Email MCP Tools (33)
email_list_accounts
List all configured email accounts and their connection status
email_add_account
Add a new IMAP or iCloud email account (Gmail and Outlook require the setup wizard for OAuth)
email_remove_account
Remove an email account: deletes its stored credentials, revokes the Google grant for Gmail accounts, and removes Outlook tokens from the local token cache. The result reports whether provider-side revocation succeeded.
email_test_account
Test an email account connection
email_list_folders
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Command Mail is categorized under Communication and uses a remote streaming HTTP/SSE transport. In contrast, Email MCP belongs to Communication using local stdio subprocess. Select Command Mail when you need capabilities focused on communication and Email MCP when you require tools for communication.
Search emails with filters. By default returns compact results without full body content to save context. Set returnBody=true to include full email bodies.
email_get
Get a single email by ID
email_get_thread
Get an email thread by thread ID
email_get_attachment
Get an email attachment by ID, returns base64 encoded data
email_save_attachment
Download an email attachment and save it directly to disk, returning metadata only (no base64 in the response) — avoids paying the token cost of round-tripping large attachments through the calling model. outputPath is relative to a fixed downloads directory (/home/user/.email-mcp/downloads, override with EMAIL_MCP_DOWNLOADS_DIR) and cannot escape it.
