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

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 Claude Desktop discover MCP tools?
When Claude Desktop starts, it reads the claude_desktop_config.json file and connects to each configured MCP server. It calls the tools/list endpoint to fetch the schema for every available tool, then surfaces them as clickable options in the chat interface via the 🔌 icon.
What happens if the MCP server is temporarily unavailable?
Claude Desktop handles disconnections gracefully. if the server is unreachable at startup, the tools simply won't appear. Once the server becomes available again, restarting Claude Desktop will re-establish the connection. There is no timeout penalty or error loop.
Can I connect multiple MCP servers simultaneously?
Yes. You can add as many servers as you need in the mcpServers section of the config file. Each server appears as a separate tool provider, and Claude can use tools from multiple servers in a single conversation turn.
Is there a limit on the number of tools per server?
Claude Desktop can handle hundreds of tools per server. However, for optimal LLM performance, Vinkius servers are designed to expose focused, well-documented tool sets rather than overwhelming the model with too many options.
Does Claude Desktop support Streamable HTTP transport?
Yes. Claude Desktop supports both SSE (Server-Sent Events) and the newer Streamable HTTP transport that Vinkius uses. Simply provide the server URL. Claude auto-negotiates the transport protocol.
Server not appearing after restart
Ensure the JSON is valid (no trailing commas). Check the file path: ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\\Claude\\ (Windows).
Authentication error
Verify your Vinkius token is correct. Go to cloud.vinkius.com to regenerate it if needed.
Tools not showing in chat
Click the 🔌 icon at the bottom of the chat input. If it shows 0 tools, the server may still be connecting. wait a few seconds.
