Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@cypht-mcp search for emails from john@example.com"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Cloudflare Worker implementation of the Cypht email MCP. It preserves the eight email tools from the Docker service while moving MCP transport to the Worker runtime and storing encrypted account records in a Durable Object.
Worker: cypht-mcp
Endpoint: https://cypht-mcp.rg1.workers.dev/mcp
Mail host: smtp.rg1.in (public IMAPS 993 and SMTP submission 587)
State: CyphtState Durable Object
Secrets: MCP_BEARER, ACCOUNT_STORE_KEY
Transport: Streamable HTTP
The Worker cannot use the Docker-only hostname mailserver-email-1; the mail server must remain reachable at the configured public hostname. Mail host validation prevents arbitrary outbound host connections.
Related MCP server: gmail-mcp
add_account, set_profile, list_accounts, send_email, list_emails, view_email, search_emails, and delete_email are registered with the same names and core arguments as the Docker implementation. search_emails is implemented as an IMAP subject/from search.
Mailbox passwords are encrypted with AES-GCM before Durable Object storage and are never returned by tools. delete_email performs an irreversible IMAP EXPUNGE.
Deployment is owned by mcp-ops: create a dev/* branch, open and merge a PR, then verify the Workers Build and authenticated MCP smoke. Do not run local Wrangler deployment from the skill tree.
