Pdbe vs Rcsb Pdb
In-depth architectural comparison of the Pdbe and Rcsb Pdb MCP servers. Compare execution transports, security boundaries, tool capabilities, quality scores, and ready-to-paste client installation snippets for Claude, Cursor, Windsurf, and VS Code.
At a Glance & Executive Verdict
Pdbe
Biology & Bioinformatics · Local stdio
Quality: 51/100 (Good) | Auth: No auth required
Rcsb Pdb
Biology & Bioinformatics · Local stdio
Quality: 41/100 (Fair) | Auth: No auth required
Verdict Summary: Choose Pdbe if you need specialized Biology & Bioinformatics tools running via a local process. Choose Rcsb Pdb if your workspace requires Biology & Bioinformatics integration with local subprocess execution. Both servers can be configured concurrently in your client's
mcpServers manifest.Which MCP Server Should You Choose?

Tools & Capabilities Breakdown
Pdbe Tools (3)
get_summary
PDBe (Protein Data Bank in Europe, EBI): get a PDB entry summary — title, experimental method, release date, source organism, and entity counts (polypeptide/ligand/water/...). Keyless. The EBI counterpart to RCSB PDB. Pass a 4-char PDB id like "1cbs".
get_molecules
PDBe (EBI): list the molecules/entities in a PDB structure — proteins, nucleic acids, and ligands, each with entity_id, molecule_type, name, and chain length. Keyless. Pass a 4-char PDB id like "1cbs".
uniprot_mappings
PDBe (EBI): SIFTS cross-database mapping of a PDB structure to UniProt — for each UniProt accession, the matching chains and residue range. Curated cross-database mappings unique to EBI. Keyless. Pass a 4-char PDB id like "1cbs".
