Materials vs Git
A side-by-side look at the Materials and Git MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Materials for research work as a local process; choose Git for version control as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Materials when
- You need dedicated capabilities in the Research domain.
- You prefer a local stdio subprocess transport.
- You want tools like
materials_search, materials_stability.
Choose Git when
- You need dedicated capabilities in the Version Control domain.
- You prefer a local stdio subprocess transport.
- Its auth model fits you: No auth required.
- You want tools like
repo_path, context_lines, target.

Tools & capabilities
Materials tools 2
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.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.

Ready-to-paste client configs
Paste either block (or both) into your client config, e.g. claude_desktop_config.json or ~/.cursor/mcp.json. We only show a config when the install command is confirmed.

Frequently asked questions
Materials is categorized under Research and uses a local stdio subprocess. Git belongs to Version Control and uses a local stdio subprocess. Pick Materials for research work and Git for version control.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
Materials has no declared pricing — check the project's own site. Git is listed as free. Auth: no auth required. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add materials and git as separate keys in the same mcpServers object, and your assistant will call tools from either one.
On AllMCPs, Materials has a quality signal of 57/100 (Good) with 2 views, 0 installs and 0 GitHub stars. Git has 81/100 (Excellent) with 49 views, 0 installs and 91,512 GitHub stars.
