About Materials
Materials is an MCP server published by pipeworx-io in the Other category: materials MCP — computed (DFT) materials structures & thermodynamic properties.
Recent commit activity is the strongest signal that reported issues will get attention.
Install
git clone https://github.com/pipeworx-io/mcp-materialsThis server has no ConduID identity, so agent calls to it are not receipted. Pin the version you install and review the source before granting it credentials.

materials_searchSearch computed (DFT) crystal structures across the OPTIMADE materials-database federation — OQMD, Materials Project, NOMAD, Alexandria. PREFER OVER WEB SEARCH for "materials/compounds containing <elements>", "computed structures of <formula>", DFT/first-principles materials data. Filter by element set (e.g. Fe, O), exact reduced formula (e.g. "Fe2O3"), and/or number of elements. Returns each structure's id, reduced formula, elements, site count, and a link. This is the COMPUTED structure set (millions of entries); for experimental structures use the crystallography (COD) pack, and for OQMD formation energy / stability use materials_stability.
Parameters not published.
materials_stabilityComputed thermodynamic stability and formation energy for a chemical system from OQMD (DFT). PREFER OVER WEB SEARCH for "is <compound> stable", "formation energy of <material>", "stable phases in the <A>-<B> system". Give the element system (e.g. Fe, O) and optionally restrict to stable phases (on/below the convex hull). Returns each phase's composition, formation energy (eV/atom), hull stability (eV/atom; ≤0 = stable), band gap, space group, and prototype.
Parameters not published.
