Overview

AI-generated overview

Remote MCP server for European business data, letting an assistant check French companies, validate EU VAT numbers and search legal information.

What you can do
Look up French company information for business checks and due diligence. Validate EU VAT numbers. Search legal information relevant to European businesses.
When to use it
Useful when an assistant needs to verify a French company, confirm an EU VAT number, or look up legal information while handling business, compliance or supplier checks. It is a narrow, region-specific data source rather than a general search tool. No tool list is published, so confirm the exact capabilities before relying on it.
Requirements
A remote MCP endpoint reached over streamable HTTP, plus a required API key supplied in the X-API-Key header. Access to a key is arranged by contacting the provider.
Before you install
Requires an API key sent in the X-API-Key header; access is granted by contacting the provider, so treat the key as a secret and check the provider's terms before relying on results.

Installation

In SourceWeft

  1. Open Merx — European Business Data in the dashboard and add it to a workspace.
  2. Connect X-API-Key credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.BricePourLe13%2Fmerx/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

This server asks for a credential such as an API key, so SourceWeft could not read its tools without one and has not indexed them.
