Side-by-Side Model Context Protocol Comparison
Interpro vs RCSB PDB
In-depth architectural comparison of the Interpro 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
Interpro
Biology & Bioinformatics · Remote HTTP/SSE
Quality: 51/100 (Good) | Auth: No auth required
RCSB PDB
Biology & Bioinformatics · Local stdio
Quality: 53/100 (Good) | Auth: No auth required
Verdict Summary: Choose Interpro if you need specialized Biology & Bioinformatics tools running via a hosted cloud SSE transport. 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?
I
Choose Interpro when:
- You need dedicated capabilities in the Biology & Bioinformatics domain.
- You prefer remote streaming HTTP/SSE transport architecture.
- Your security boundary fits: No auth required (Free / Open Source).
- Primary tools included: search_entries, get_entry, entries_for_protein.
R
Choose RCSB PDB when:
- You need dedicated capabilities in the Biology & Bioinformatics domain.
- You prefer local stdio subprocess transport architecture.
- Your security boundary fits: No auth required (Free / Open Source).
- Primary tools included: rcsb_list_pdb_search_attributes, rcsb_find_go_terms, rcsb_find_interpro_domains.

Tools & Capabilities Breakdown
Interpro Tools (3)
search_entries
Search InterPro for protein families, domains, repeats and functional sites by keyword (text search over entry names/accessions). InterPro is EBI's integrated protein-signature classification (Pfam, PROSITE, SMART, CDD, PANTHER, ...). Returns matching entries with accession (IPRxxxxxx), name, type…
get_entry
Get full details for a single InterPro entry by accession (e.g. "IPR000001"). Returns the entry name, type, a plain-text description, member-signature/protein counters, and associated GO terms (molecular function / biological process / cellular component). Use after search_entries or entries_for_pr…
entries_for_protein
List all InterPro entries (families, domains, sites) found on a given UniProt protein, by UniProt accession (e.g. "P12345"). Returns each matching InterPro signature with accession, name and type. Useful to functionally annotate a protein. Complements UniProt/AlphaFold. Keyless.
