What is the RCSB PDB MCP Server?
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
- Subscribe to this server
- 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
Built-in capabilities (2)
PDB 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
Why LlamaIndex?
LlamaIndex agents combine RCSB PDB tool responses with indexed documents for comprehensive, grounded answers. Connect 2 tools through Vinkius and query live data alongside vector stores and SQL databases in a single turn. ideal for hybrid search, data enrichment, and analytical workflows.

Frequently asked questions
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.
How does LlamaIndex connect to MCP servers?
Use the MCP client adapter to create a connection. LlamaIndex discovers all tools and wraps them as query engine tools compatible with any LlamaIndex agent.
Can I combine MCP tools with vector stores?
Yes. LlamaIndex agents can query RCSB PDB tools and vector store indexes in the same turn, combining real-time and embedded data for grounded responses.
Does LlamaIndex support async MCP calls?
Yes. LlamaIndex's async agent framework supports concurrent MCP tool calls for high-throughput data processing pipelines.
