Augmented-Nature/PDB-MCP-Server

Exposes PDB search, structure retrieval, and quality validation through five core tools and URI-based resources, enabling direct access to multiple coordinate formats (PDB, mmCIF, mmTF, XML) and validation metrics like resolution, R-factors, and clash scores. Integrates with RCSB PDB's REST, Search, and File Download APIs via stdio transport for seamless integration with Claude Desktop and complementary servers like UniProt and AlphaFold MCP. Implements comprehensive error handling for API rate limiting, invalid identifiers, and network failures.
