What is the RCSB PDB MCP Server?
The RCSB PDB MCP Server gives AI agents like Claude, ChatGPT, and Cursor direct access to RCSB PDB via 2 tools. Explore 220K+ 3D molecular structures — search proteins, DNA, and RNA by name, experimental method, resolution, and bound ligands from the Protein Data Bank. Powered by the Vinkius - no API keys, no infrastructure, connect in under 2 minutes.
Built-in capabilities (2)
Tools for your AI Agents to operate RCSB PDB
Ask your AI agent "Show me the structure of the SARS-CoV-2 main protease." and get the answer without opening a single dashboard. With 2 tools connected to real RCSB PDB data, your agents reason over live information, cross-reference it with other MCP servers, and deliver insights you would spend hours assembling manually.
Works with Claude, ChatGPT, Cursor, and any MCP-compatible client. Powered by the Vinkius - your credentials never touch the AI model, every request is auditable. Connect in under two minutes.
Why teams choose Vinkius
One subscription gives you access to thousands of MCP servers - and you can deploy your own to the Vinkius Edge. Your AI agents only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure and security, zero maintenance.

RCSB PDB MCP Server capabilities
2 toolsPDB IDs are 4-character codes like 1HHO, 6LU7, 7BNN. Get full structural details by PDB ID
Returns PDB ID, title, experimental method (X-ray, Cryo-EM, NMR), resolution, authors, and bound ligands. Essential for drug discovery and structural biology. Search 220K+ 3D molecular structures in the Protein Data Bank
What the RCSB PDB MCP Server unlocks
Connect your AI agent to the RCSB Protein Data Bank — the world's repository of experimentally determined 3D structural data for biological macromolecules.
What you can do
- Structure Search — Find protein, DNA, and RNA structures by name, function, disease association, or organism across 220K+ experimentally determined entries
- PDB Entry Lookup — Get complete structural details by 4-character PDB ID (e.g., 1HHO for hemoglobin, 6LU7 for SARS-CoV-2 main protease) including experimental method, resolution, and bound molecules
How it works
1. Subscribe to this server
2. Start searching molecular structures immediately — no API key required
Who is this for?
- Structural Biologists — quickly access experimental metadata, resolution, and method details for molecular structures
- Drug Discovery Teams — find protein-ligand co-crystal structures for structure-based drug design and virtual screening
- Biochemistry Students — understand protein architecture by exploring real experimental structures with annotations
Frequently asked questions about the RCSB PDB MCP Server
What experimental methods are represented in the PDB?
The PDB contains structures determined by four main methods: X-ray Crystallography (85% of entries, atomic resolution), Cryo-EM (rapidly growing, now 15%+ of new deposits), NMR Spectroscopy (solution-state structures), and Neutron Diffraction (hydrogen atom positions). Each entry lists its method and resolution.
Do I need authentication to access PDB data?
No. RCSB PDB is completely free and open — funded by NSF, NIH, DOE, and international partners. All 220K+ structures are openly accessible without any registration or API key. The data is licensed under CC0 (public domain).
What information does each PDB entry contain?
Each entry includes: PDB ID (4-character code), structure title, depositing authors, experimental method, resolution in Ångströms, source organism, release date, number of polymer chains, and bound non-polymer ligands (drugs, cofactors, ions). Higher resolution (lower number) means more precise atomic coordinates.
