This server has a remotely hosted endpoint. Open its connector listing for connection details, authentication requirements, and setup instructions:
CommsHarbor provides email for your domain, with webmail, IMAP and SMTP. Its remote MCP server helps an assistant read the email workspace, prepare domain setup, check DNS verification, and manage authorized mailboxes and aliases. This repository contains the connection settings and a user skill. The hosted service runs at commsharbor.com.
The server uses Streamable HTTP. No local program is required. Add this to .vscode/mcp.json for GitHub Copilot
in VS Code:
{
"servers": {
"commsharbor": {
"type": "http",
"url": "https://commsharbor.com/mcp?checkout=site"
}
}
}For Cursor, use the same entry under mcpServers in .cursor/mcp.json. For other clients, select an HTTP server
and enter the URL above. The official registry entry is com.commsharbor/commsharbor.

Start with: "Show the available CommsHarbor email plans."
commsharbor_email_plans reads the public plans and storage allowances.
commsharbor_email_workspace reads an authorized organization's workspace.
commsharbor_email_domain_setup checks a domain before purchase without creating a charge.
Other authorized tools create mailboxes and aliases, verify domains and read setup jobs.
Public discovery requires no account. Workspace operations require organization access. Use an organization API
key through the client's secret storage and the X-Api-Key header. Supply the organization_id requested by the
tool. Never commit a key to the client configuration. Read the API contract
for each tool's required fields and permissions.
Create the account and select the email service on the website. The receive-only trial and sending plans have different permissions. The connection above disables payment transactions through the assistant. Mailbox passwords and message content are not returned by workspace reads. Campaigns and transactional sending APIs are not part of the current offer.
