Claude Code Claude Desktop Codex Cursor VS Code

run in your terminal

claude mcp add mastr-mcp-server -- uvx mastr-mcp-server

This one needs environment variables set before it will start: MASTR_USER (MaStR Marktakteur number (SOM/SEM...) for SOAP API access. Without credentials, only 7 public tools are available.), MASTR_TOKEN (MaStR web service token (~540 chars) for SOAP API access. Enables 14 additional SOAP tools.). The author declared them in the registry entry; get the values from the project itself.

MaStR MCP Server — questions

Answers built from our own checks of this server.

Why is there no uptime for MaStR MCP Server?

MaStR MCP Server runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the pypi package mastr-mcp-server was installed 75 times last week.

How do I connect MaStR MCP Server?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls mastr-mcp-server straight from pypi; nothing to host, nothing to sign up for.

How many people use MaStR MCP Server?

The pypi package mastr-mcp-server was installed 75 times in the last week. Week over week that is -12%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is MaStR MCP Server open source?

Yes — it is published under the MIT licence, written in Python and 6 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
