Echtpost MCP with Claude: Secure Encrypted Document and Message Exchange
The short answer
Claude works with Echtpost through the Model Context Protocol (MCP), an open standard that acts like a universal adapter. Once connected with an API key, Claude can send encrypted documents, deliver confidential messages, fetch secure communications and adjust privacy settings from a plain-English request, with your organisation controlling what it can access.
What is Echtpost?
Echtpost is a secure digital communication platform for exchanging encrypted documents and messages. It is designed to keep confidential information private while it travels between people and organisations. Teams that handle sensitive material, such as legal, finance, HR, healthcare administration and client services, often use it when ordinary e-mail is not suitable. It helps protect data during transmission so that only the intended recipients can access it.
How Claude connects to Echtpost through MCP
The Model Context Protocol (MCP) is an open standard that lets Claude securely use other software, reading information and taking actions, with permissions your organisation controls. Think of it as a universal adapter between Claude and the tool. For Echtpost, this means Claude can work with your secure messaging without anyone copying files or content by hand.
Once connected, Claude can typically send encrypted documents to named recipients, deliver confidential messages, fetch secure communications that have been sent to your team, and manage privacy settings through natural language. A staff member might ask Claude to prepare a message and attach a contract, and Claude carries out the secure send within the boundaries you have set.
Permissions and approvals keep people in charge. Access is granted with a dedicated API key that can be limited to the actions each workflow needs. Consequential steps, such as sending a document outside the organisation, can require a human to review and approve before they happen. Every action can be logged so that you have a clear record of what was done and by whom.
What you can automate
Sending contracts to clients
A legal or commercial team can ask Claude to send a signed agreement to a client through Echtpost. Claude prepares the covering message, attaches the encrypted document and records the send. A reviewer confirms the recipient list before anything leaves the organisation, reducing the risk of a document going to the wrong person.
Delivering confidential HR letters
HR teams often need to send offer letters, policy notices or payslips that must stay private. Claude can prepare each letter from a template, deliver it to the right employee through Echtpost and track which messages have been fetched. Sensitive personal details stay within the secure channel rather than in ordinary inboxes.
Collecting sensitive documents from customers
Finance or compliance teams may need customers to return identity or financial documents securely. Claude can check for new incoming secure communications, pull them into the right case folder and notify the responsible officer. This can shorten the time between receipt and review, while keeping the material protected.
Managing privacy settings at scale
Administrators can ask Claude to review and update privacy settings across a group of users or messages in plain language. For example, a request to tighten retention on a particular department's communications can be carried out consistently, with the change recorded for audit purposes.
Routine secure reporting
Operations teams that send regular confidential reports to partners can schedule a workflow in which Claude compiles the figures, creates the document and dispatches it securely each month. A manager reviews the draft before the scheduled send, keeping control over what is shared.
An end-to-end workflow: Secure client onboarding pack
TriggerA new client is marked as won in the CRM system.
Claude reads the new client record from the CRM, including the contact name and agreed service.
Claude assembles the onboarding pack, such as the welcome letter, terms of service and data processing agreement, from approved templates.
The account manager reviews the pack and approves the recipient list.
Claude sends the pack as encrypted documents through Echtpost using the approved privacy settings.
Claude logs the send in the ticketing system and assigns a follow-up task to the onboarding team.
Claude checks Echtpost for any secure reply from the client and alerts the account manager when one arrives.
OutcomeOnboarding documents reach new clients quickly and securely, with a clear audit trail in the CRM and ticketing system, and staff spend less time on manual sending and filing.
How we set it up
Book a free automation audit
We review how your teams currently send confidential documents and messages, and identify the workflows worth automating first with Echtpost and Claude.
Set up secure access
We connect Claude to Echtpost using an API key, which is stored securely and limited to the actions each workflow needs. You keep ownership of the key and can revoke it at any time.
Design the workflow
We map the end-to-end process across Echtpost and your other systems, such as Microsoft 365, CRM, ERP or ticketing, and decide which steps require human approval.
Test against real cases
We run the workflow against past examples to confirm that documents reach the correct recipients, privacy settings are applied and exceptions are handled properly.
Launch, monitor and train
We go live with monitoring and audit logs in place, and train your team on how to use Claude with Echtpost safely and confidently.

For teams in the US, UK, India and the Middle East
Organisations in the United States and the United Kingdom can set up Claude workflows that respect their own data protection and sector-specific rules. In India, workflows are designed with the Digital Personal Data Protection Act, 2023 in mind. For organisations in the Middle East, including the UAE and Saudi Arabia, data protection laws shape how documents and personal information are handled. Where needed, the hosting region for custom applications can be chosen to meet your specific requirements.

Frequently asked questions
What does the Echtpost MCP server do?
The Echtpost MCP server acts as a bridge between Claude and your Echtpost account. It lets Claude send encrypted documents, deliver confidential messages, fetch secure communications and manage privacy settings using requests written in plain language. You control which actions are permitted, and the server works within those limits.
Is connecting Claude to Echtpost secure?
Security depends on how the connection is configured. Access uses an API key that can be limited to specific actions and revoked at any time. Approvals can be required for sensitive steps, and audit logs record activity. We design and test the setup with your IT team before launch.
What can Claude do with Echtpost once connected?
Typically, Claude can send encrypted documents to named recipients, deliver confidential messages, retrieve secure communications sent to your team and adjust privacy settings. It can also combine these actions with other systems, such as sending a document after a CRM record is updated, provided the workflow has been approved.
How long does setup take?
Timelines vary with the complexity of your workflows and the systems involved. A focused set of workflows can often be designed, tested and launched within a few weeks, following the free automation audit. We agree the timeline with you during the audit.
Which plan or permissions do I need?
Generally, you need an Echtpost account with an API key that has permission for the actions you want Claude to perform. The exact plan and permission requirements depend on how your Echtpost account is set up, so we confirm these during the free automation audit.
