Welect’s MCP Server: Discover choice-driven advertising directly in your AI workflow

What is an MCP server?

An MCP server is like a bridge between an AI (e.g., ChatGPT or Claude) and other programs or data sources. This allows the AI not only to generate text but—if permitted—to retrieve specific information, find documents, or perform small tasks in connected systems. In short, an MCP server enables AI to work practically with real tools and data instead of just responding in a chat.

What our MCP server is able to do?

Our Welect MCP Server connects AI assistants with selected Welect data and small helper functions so they can arrive at reliable answers more quickly—without having to manually gather everything. The Welect MCP Server provides LLMs with three tools that are used based on your questions: a knowledge base, a signal loss tool, and a selection from our site list.

Here’s a practical example:

Instructions for connecting

To make it as easy as possible for you to try it out, we’ve put together instructions below for three of the most well-known LLMs: Claude, Perplexity, and ChatGPT. Please note the following:

The instructions below apply only to the web app versions of these LLM clients, as they offer the simplest (and sometimes the only) way to connect custom MCP servers.
These LLM clients are constantly being updated, so some details in the user interface may differ from those shown in the screenshots (even though we try to keep everything up to date).

Claude

In your browser, go to the connector settings at https://claude.ai/settings/connectors. There, click on “Add custom connector.”

null

Enter the following and add it:

Name: Welect
Remote MCP Server URL: https://mcp.welect.de/mcp

null

In a new chat, add the Welect MCP Server to the conversation:

+ Symbol → Connectors → welect.

null

Done. When you ask a question related to Welect, our MCP server will also be queried.

Perplexity

In your browser, go to the connector settings at https://www.perplexity.ai/account/connectors. There, click the “+ Custom Connector” button in the top right.

null

In a new chat, enable the Welect MCP Server as a source: either 1) type @welect in the chat.

null

or 2) click the + icon → Connectors and sources → select the checkbox next to Welect. You may want to disable “Web” as a source if you want to get information exclusively from our MCP server.

Done. When you ask a question related to Welect, our MCP server will also be queried.

ChatGPT

Note: ChatGPT currently only allows the integration of custom connectors in a developer mode.

In the ChatGPT web app, either 1) open the Apps view at https://chatgpt.com/apps and click the settings (gear icon in the top right), or 2) go directly to the connector settings page at https://chatgpt.com/apps#settings/Connectors.

Under Settings → Apps, click on “Advanced Settings.”
