At a Glance & Executive Verdict
MCP Server Mysql
Databases · Local stdio
Quality: 52/100 (Good) | Auth: other
Crystallography
Databases · Local stdio
Quality: 43/100 (Fair) | Auth: No auth required
Verdict Summary: Choose MCP Server Mysql if you need specialized Databases tools running via a local process. Choose Crystallography if your workspace requires Databases integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose MCP Server Mysql when:
You need dedicated capabilities in the Databases domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: other (Free / Open Source).

Search the Crystallography Open Database (COD), an open repository of crystal structures (inorganic, organic, metal-organic, and mineral). Search by compound name (free text), chemical formula, or mineral name; returns matching crystal structures with unit-cell parameters, space group, year, and a…
get_structure
Look up a single crystal structure in the Crystallography Open Database (COD) by its numeric COD ID (e.g. "1009000"). Returns the compound/mineral name, chemical formula, space group, full unit-cell parameters (a, b, c, alpha, beta, gamma, volume), bibliographic details (title, authors, journal, ye…
get_cif
Fetch the full CIF (Crystallographic Information File) for a COD structure by its numeric COD ID — the actual machine-readable structure: symmetry operations and the atom sites (element, fractional x/y/z coordinates, occupancy). Use after search_structures/get_structure when you need the real atomi…
