Mrd Overview
The mrd MCP server connects AI assistants to machine-readable specifications for more than 2,500 spacecraft hardware products. It supports requirement-based component matching, datasheet searches, stack design, and mass or steady-state power budgets through hosted MCP or a local stdio bridge. Reach for it when a trade study needs traceable vendor data, page references, explicit missing fields, or category-wide comparisons. Reading data requires no authentication, while an optional key increases rate limits.
Primary Use Cases for Mrd:
- Match spacecraft components against mass, voltage, performance, and price requirements
- Compare datasheet facts across a hardware category with page citations
- Build a spacecraft stack and estimate mass and steady-state power
- Find missing specifications before contacting a vendor
