mxHERO Mail2Cloud Advanced — Enterprise Email Search MCP ServerVerifiedFeatured

What is mxHERO Mail2Cloud Advanced MCP?

mxHERO Mail2Cloud Advanced MCP (mxMCP) connects AI assistants such as Claude and ChatGPT to your organization's email archive. Years of correspondence across teams, departments, and mail systems become searchable in plain language, with access governed by your own permissions and audit trail.

Your emails are captured selectively, stored in your own cloud storage (such as Box), and indexed for AI search. Models can find and cite the original messages without ever being able to alter or delete them.

How to use it

1. Try the demo. Connect the MCP server to your AI client and explore pre-loaded demo accounts. No signup or email access required.
2. Go to production. Connect to your company's email and cloud storage with a Mail2Cloud Advanced subscription.
3. Ask questions in natural language, for example:
   • "What did we agree with the vendor about renewal pricing in 2023?"
   • "Summarize the correspondence with the client about the Riverside project."
   • "Find every email where the contract termination clause was discussed."

Authentication uses OAuth 2.1 with PKCE, so your AI client signs in securely without shared API keys.

Key features

• Selective capture: Archive only what matters, using filters by sender, domain, folder, date, and more.
• Search beyond context limits: A vector index lets models search millions of emails and retrieve only the relevant ones, instead of stuffing a mailbox into a prompt.
• Multi-account, governed access: Search across teams and mail systems while respecting who is allowed to see what.
• Read-only by design: Original emails stay intact. Nothing an AI does can delete or modify your archive.
• Works with your AI of choice: Any MCP-compatible client, including Claude and ChatGPT.
• Enterprise-grade security: mxHERO is SOC 2 Type 2 certified.

Use cases

• Knowledge recovery: Retrieve institutional knowledge when employees leave or projects change hands.

• Insurance, construction, and engineering: Reconstruct claim, project, or job timelines from years of scattered email threads.
• Sales and customer success: Pull the full history of an account before a renewal or escalation.
• AI workflows and agents: Give your own agents trustworthy email context to search, analyze, and summarize.
