MaStR MCP Server
Query Germany’s MaStR energy market register from your agent while building cleantech, grid, or compliance tooling.
Overview
MaStR MCP Server is a MCP server for the Build phase that exposes German Marktstammdatenregister public and SOAP energy-register tools to agents over stdio.
What is this MCP server?
- 7 public MaStR tools available without MaStR credentials
- 14 additional SOAP API tools when MASTR_USER and MASTR_TOKEN are configured
- Python PyPI package mastr-mcp-server (v1.0.1) with stdio transport
- Focused on German Marktstammdatenregister energy market master data
- Credential-gated expansion from public browse to authenticated SOAP operations
- 7 public tools without MaStR credentials
- 14 additional SOAP tools with MASTR_USER and MASTR_TOKEN
- PyPI package version 1.0.1 with stdio transport

What problem does it solve?
Building German energy products means wrestling with MaStR SOAP credentials and obscure register APIs while your agent cannot access the dataset natively.
Who is it for?
Solo builders creating Germany-focused solar, grid, or energy-market SaaS who need agent-driven MaStR access during backend integration.
Skip if: US-only real estate or generic web apps with no MaStR dependency, or teams unwilling to manage MaStR Marktakteur credentials.
What do I get? / Deliverables
Your agent can call structured MaStR tools—seven public and up to fourteen authenticated—so integration scaffolding and data probes ship faster.
- Queryable MaStR register data via seven public MCP tools
- Expanded SOAP-backed operations when credentials are configured
- Faster agent-assisted integration design for German energy apps
Recommended MCP Servers
Journey fit
Build is canonical because the server wires a specialized government energy dataset into your product or agent workflows during integration work. Integrations reflects SOAP and public MaStR tool surfaces that you embed behind your own API or internal ops dashboards.
How it compares
Government energy-register data MCP—not a general open data browser or UI component documentation server.
Common Questions / FAQ
Who is MaStR MCP Server for?
Developers and solo founders building German energy or cleantech software who want MCP-shaped access to Marktstammdatenregister data.
When should I use MaStR MCP Server?
Use it during Build while wiring register lookups, validation flows, or ops dashboards that depend on MaStR master data.
How do I add MaStR MCP Server to my agent?
Install the PyPI package mastr-mcp-server, configure stdio in your MCP host, and set MASTR_USER plus MASTR_TOKEN for full SOAP tool access.
