MCP development: connecting AI assistants to your systems

Your AI assistant gets access to your data and tools, controlled and secure

The Model Context Protocol (MCP) is the open standard that lets AI assistants like Claude or ChatGPT access company systems: calendar, inventory, CRM, databases, line-of-business applications. I develop MCP servers that expose exactly the functions you want to expose.

An AI assistant that does not know your data can only give generic answers. An MCP server changes that: the assistant can query stock, create appointments, search orders or generate reports, using data from your systems and with the permissions you define.

MCP is an open standard initiated by Anthropic and now supported by many vendors. An MCP server developed once works with different assistants and tools. I develop MCP servers in Ruby or TypeScript, with authentication, logging and clearly limited permissions.

What you get

  • Answers from your data

    "How many units of item 4711 are in stock?" or "Which quotes expire this week?" are answered from the live system.

  • Permissions stay with you

    Every function is exposed deliberately. Read, write, delete: you decide what the assistant may and may not do.

  • One standard, many tools

    MCP servers work with Claude, ChatGPT, developer tools and your own applications. No vendor lock-in.

  • Traceable

    Every access is logged. You see who queried or changed what and when.

Understandable real-world examples

MCP server for a community and touring platform

Starting point
A community platform for motorcyclists maintains tours, places and events. Creating and maintaining content is tedious and happens exclusively through forms.
Solution
An MCP server that exposes tours, places, images and events as tools. Editors can search, create, extend and publish content via an AI assistant, with a permission check per action.
Result
Content is maintained in conversation with the assistant, errors caused by rigid forms disappear, every action remains traceable. This example is live: I run this MCP server myself.

Stock and order information for sales

Starting point
The field sales team of a wholesaler calls the back office to ask about stock and delivery times. The ERP system is only reachable from the office PC.
Solution
An MCP server with read access to items, stock and orders. Sales staff ask the assistant on their smartphone: "Can we deliver 50 units of item X by Friday?"
Result
Answers at the customer's site in seconds, back office relieved, no database credentials on mobile devices.

Assistant for accounting

Starting point
A tax firm wants to answer client questions faster without staff opening several systems.
Solution
MCP servers for the practice software and the document management system with strict client separation. The assistant finds receipts, deadlines and open items for the client that has been released.
Result
Answers in one tool instead of four, client separation technically enforced, every access logged.

How we work together

  1. 1

    Free initial consultation

    30 minutes by phone, video or on site in and around Eisenach. You describe what costs time or causes friction today. I tell you honestly whether and how AI can help.

  2. 2

    Analysis and concept

    I look at the workflow, the data and the systems involved. You receive a short concept with effort, benefit and risks in plain language.

  3. 3

    Implementation in small steps

    First a working prototype, then the build-out. You see results early and keep control over budget and direction.

  4. 4

    Rollout and support

    Training for your team, documentation, monitoring. On request I take care of maintenance and further development.

Frequently asked questions

What exactly is MCP?
The Model Context Protocol is an open protocol that lets AI applications use tools and data from external systems. An MCP server describes which functions exist (for example "query stock") and executes them on the assistant's request.
Can our data leak through this?
The MCP server only exposes the functions and data fields we define. In addition, the model can be chosen so that data are processed within the EU or on your own server. We design the data flow together in the concept phase.
Which systems can you build MCP servers for?
Anything with an interface or a database: Ruby on Rails applications, REST APIs, MySQL/PostgreSQL, DATEV exports, CRM systems, ticket systems, calendars. For closed systems I check the available access options in advance.
Do we need a development department?
No. I take care of development, operation and maintenance. Your employees use the assistant as usual, just with more knowledge.
