BioHarbor vs Rcsb Pdb
A side-by-side look at the BioHarbor and Rcsb Pdb MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose BioHarbor for biology & bioinformatics work as a local process; choose Rcsb Pdb for biology & bioinformatics as a local process. You can also run both side by side in one mcpServers block.

Frequently asked questions
BioHarbor is categorized under Biology & Bioinformatics and uses a local stdio subprocess. Rcsb Pdb belongs to Biology & Bioinformatics and uses a local stdio subprocess. Pick BioHarbor for biology & bioinformatics work and Rcsb Pdb for biology & bioinformatics.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
BioHarbor has no declared pricing — check the project's own site. Rcsb Pdb has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add bioharbor and rcsb-pdb as separate keys in the same mcpServers object, and your assistant will call tools from either one.
