At a Glance & Executive Verdict
Crystallography
Databases · Remote HTTP/SSE
Quality: 48/100 (Fair) | Auth: No auth required
Mysql MCP Server
Databases · Local stdio
Quality: 65/100 (Great) | Auth: other
Verdict Summary: Choose Crystallography if you need specialized Databases tools running via a hosted cloud SSE transport. Choose Mysql MCP Server 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?
C
Choose Crystallography when:
You need dedicated capabilities in the Databases domain.
You prefer remote streaming HTTP/SSE transport architecture.
Your security boundary fits: No auth required (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…

Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Crystallography is categorized under Databases and uses a remote streaming HTTP/SSE transport. In contrast, Mysql MCP Server belongs to Databases using local stdio subprocess. Select Crystallography when you need capabilities focused on databases and Mysql MCP Server when you require tools for databases.
