MCP Server: Integrations for Your AI Workflow

MCP servers are becoming the backbone of modern AI workflows: Using the Model Context Protocol, they connect language models such as Claude or ChatGPT with tools such as Zapier, HubSpot or GitHub — without you having to program every integration yourself.

‍

The following is a practical overview that explains the idea behind MCP Server, classifies the most important providers and shows you how you can use these components specifically in your own AI setup.

MCP server: bridge between AI model and tech stack

‍

MCP stands for Model Context Protocol - an open standard that describes how AI models communicate securely with external systems An MCP server is the “bridge”: It executes tools (e.g. “create ticket”, “retrieve customer data”) and delivers structured answers back to the model.

‍

Technically speaking, the MCP server provides a manifest with available tools, defines authentication, input parameters and return formats, and takes care of logging and error handling. As a result, the language model doesn't have to “know” what the HubSpot or Stripe API looks like in detail — it simply calls up a clearly described tool.

‍

For companies, the MCP server thus becomes a central integration layer: Instead of maintaining many individual plugins, you connect structured servers and can use them in various clients — such as in Claude Desktop, development environments or your own AI assistant.

‍

Another advantage: You can run MCP servers locally, in your cloud, or as a hosted service. This opens up leeway when it comes to data protection, performance and governance — especially in regulated industries.

‍

Important selection criteria for companies

‍

Before you use an MCP server productively, it's worth taking a structured look at a few key criteria. The list of 16 MCP servers presented in the VisualMakers article is easy to evaluate along these points.

‍

Supported systems and actions
An MCP server is only as valuable as the tools it unlocks. Check which objects and actions are supported (e.g. tickets, deals, payments, files) and whether they match your specific use cases.

‍

Security, Auth & Scopes
Good MCP servers work with finely granulated permissions: API keys, OAuth scopes, separate read/write rights, and clearly defined endpoints. This ensures that your AI agent is only allowed to do what he really should.

‍

Hosting & data location
Especially in a corporate context, it is relevant whether the MCP server is hosted (Zapier, Make, Cloudflare) or runs in your own infrastructure (e.g. n8n self-hosted). This affects data protection, latency, and costs.

‍

Rate limits, monitoring & maintenance
Official MCP servers from providers are usually maintained in parallel with their APIs and include logging, limits and error codes — an important difference from community servers, which are more demo in nature.

‍

If these basics fit, you can use MCP Server specifically as building blocks in an agentic AI architecture — from automation to analysis.

‍

‍

Automation with Zapier, Make, and n8n

‍

Many of the most important MCP servers revolve around automation - meaning that your AI can directly trigger workflows in tools such as Zapier, Make or n8n.

‍

Zapier MCP Server
The official Zapier MCP server makes thousands of apps accessible without you having to write integrations yourself. Your model can trigger Zaps, write data to CRM systems, or send notifications—all using natural language while Zapier manages authentication and limits.

‍

Make MCP Server
With the Make MCP Server, your scenarios become tools: Every approved workflow is available to the AI model as an action — from lead routing to complex data transformations. Particularly exciting: You can continue to use existing make automations and “just” consider voice-based control.

‍

n8n MCP server
n8n now comes natively with MCP support. In the workflow, you mark certain nodes as tools, activate the MCP trigger - and your AI agents can perform exactly these steps, whether locally or in the n8n cloud. For data-sensitive scenarios, the self-hosted N8n-MCP server is particularly interesting because all data remains in your infrastructure.

‍

With these automation MCP servers, you lay the basis for AI not only generating answers, but also reliably implementing tasks in your business systems.

‍

‍

‍

MCP Server: Use infrastructure and developer integrations

‍

In addition to automation, there are MCP servers that are specifically aimed at developer teams and infrastructure managers. They make logs, deployments or code repos controllable directly from the AI.

‍

Cloudflare MCP Servers
With Cloudflare MCP servers, you get tools for DNS analytics, workers monitoring, key-value storage, and log queries. For example, an AI assistant can search for errors in edge logs, create namespaces, or check configurations without anyone having to click through multiple dashboards.

‍

GitHub MCP servers
The GitHub MCP server allows you to create issues, list pull requests, start workflows, or search repository files — all as standardized tools. Developers can use AI assistants to prepare code reviews, analyze logs, or initiate CI jobs.

‍

Supabase MCP Server
Postgres databases and other project resources are directly accessible to LLM clients via the Supabase MCP server. An MCP server can query tables, read logs, or pause projects while you fine-grained control of auth and permissions.

‍

Figma Dev Mode MCP Server
Figma provides a local MCP server in Dev Mode, which makes design frames available for AI models. Developer agents can generate React or Tailwind snippets from this, read out design tokens or create component lists — the path from design to code is significantly shorter.

‍

These MCP servers show that AI integration goes far beyond chatbots: They go deep into dev and infra processes and make technical contexts directly usable for AI.

‍

‍

‍

Data, translation and research at your fingertips

‍

Another block of the MCP servers presented takes care of content, translations and research. This is about your model being able to use structured data and high-quality voice services.

‍

DeepL MCP Server
With the DeepL MCP server, translations, paraphrases, and language lists can be embedded directly into agency workflows. Your MCP server provides tools for translation and reformulation, including optional glossaries or levels of formality — ideal if your assistant needs to support multilingual communication.

‍

Firecrawl MCP Server
Firecrawl provides an MCP server that crawls websites, extracts content, and returns it in a structured format (such as Markdown). An AI agent can use it to collect current web information, condense long pages or create thematic dossiers — without building their own scrapers.

‍

Perplexity MCP Server
The Perplexity MCP server makes the provider's Sonar Search API accessible. The model can make targeted search queries, receives summarized results with sources and can enrich answers with citations — an important building block for verifiable AI answers.

‍

With these data and research MCP servers, you can build AI workflows that are not only based on training data, but can actively research, translate and update content.

‍

‍

‍

CRM, payments and content in combination

‍

It gets particularly exciting when MCP servers connect directly to sales and customer data. The VisualMakers article shows how wide the spectrum is now — from CRM to design.

‍

HubSpot MCP Server
The HubSpot MCP server opens contacts, deals, tickets, and tasks for your AI agents. You can create new contacts, summarize open deals, or update tickets — always under the defined permissions of your token.

‍

Linear MCP Servers
With the Linear MCP Server, your project management system becomes an API for AI assistants. Create, prioritize, search or update issues — all via a tool call, neatly logged in the issue history.

‍

Notion MCP Server
The Notion MCP server makes selected pages and databases available. An MCP server can search for content, create new pages or maintain database entries — ideal for knowledge and project documentation that is to be maintained by AI.

‍

Stripe and PayPal MCP servers
Stripe and PayPal offer MCP servers that can be used to initiate payments, invoices, subscriptions or refunds — under strict scopes and with clear audit logs, of course. For example, an AI assistant can check invoices, initiate payments, or summarize payment statuses without direct access to your productive accounts.

‍

Canva MCP server
The Canva MCP server connects your design archive with AI. Assistants can create presentations, reformat assets or adapt existing designs — for example, to generate a new pitch deck directly from a chat conversation.

These MCP servers show that along the customer journey — from initial contact to offer to invoice — more and more steps can be controlled directly via AI.

Practical tips for implementing MCP in a company

For MCP servers to work in everyday life, you should not only keep an eye on technology, but also on organization and security.

1. Start small, clearly limit
   Start with a few, easy-to-understand MCP servers (e.g. HubSpot + Zapier) and clearly defined tools. This allows you to gain experience before you open your entire stack.
2. Take scopes and permissions seriously
   Use restrictive tokens: rather just read or only release certain objects, instead of “All Access”. MCP servers make it easy to set these limits precisely.
3. Set up monitoring and logging
   Make sure that all calls to your MCP servers are logged. This allows you to understand which actions an AI agent has triggered — important for security and compliance.
4. Embed MCP servers into governance
   Define who releases new MCP servers, who maintains manifests, and how changes are tested. Without clear responsibilities, there is a risk of confusing wild growth.
5. Train teams
   Developers, ops teams and departments should understand what an MCP server is, what it is allowed to do — and what not. Good introductory materials and guides help to avoid operating errors.

This makes MCP servers a stable component of your corporate AI — not an uncontrolled risk.

MCP Server: FAQ for beginners

‍

What is an MCP server in simple terms?

An MCP server is a service that defines which actions an AI can perform in a system - such as “create contact in HubSpot” or “save file in Supabase.” It addresses the respective API, takes care of authentication and returns structured answers to the model.

‍

Why MCP servers instead of classic plugins?

In contrast to individual plugins, an MCP server works according to an open standard and can be used by various clients. You only have to build integrations cleanly once and can then use them in several assistants — such as Claude Desktop, IDEs or internal chatbots.

‍

Are MCP servers secure enough for production data?

Yes, if they are properly configured. Official MCP servers from the providers usually come with sophisticated auth mechanisms, rate limits and logging. It is crucial that you issue tokens with minimal rights, limit sensitive actions and monitor calls.

‍

Do I need my own MCP servers or are official ones enough?

Official MCP servers are sufficient for many scenarios — such as Zapier, HubSpot or Stripe. As soon as you want to connect internal systems, legacy software or special databases to AI, it's worth having your own MCP server, which you build in Python, TypeScript or with low-code tools such as n8n.

‍

How do I get started with MCP servers in practice?

A typical start: connect an official MCP server (e.g. HubSpot or GitHub) to an existing AI client, release a few tools, test the first use cases - and in parallel check which internal systems can be connected via your own MCP servers.
