Connects Claude to the Crystallography Open Database through Pipeworx's gateway infrastructure. The source doesn't list specific tools, but COD typically offers crystal structure searches, lattice parameter lookups, and chemical formula queries across hundreds of thousands of crystallographic entries. You'd reach for this when working with materials science data, analyzing crystal structures, or building chemistry research workflows. Part of Pipeworx's larger gateway that bundles 834+ data sources, so you can either connect to just the crystallography endpoint or grab the full gateway. Supports the ask_pipeworx natural language interface if you prefer asking questions instead of calling tools directly.
Crystallography Open Database (COD) MCP.
Part of Pipeworx — an MCP gateway connecting AI agents to 834+ live data sources.
| Tool | Description |
|---|
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"crystallography": {
"url": "https://gateway.pipeworx.io/crystallography/mcp"
}
}
}
Or connect to the full Pipeworx gateway for access to all 834+ data sources:
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"
}
}
}
Instead of calling tools directly, you can ask questions in plain English:
ask_pipeworx({ question: "your question about Crystallography data" })
The gateway picks the right tool and fills the arguments automatically.
