How to install
- Claude Science — enable the Structures & Interactions featured connector. These featured connectors are Anthropic-hosted and have no separately addressable per-connector MCP URL.
- Public API — the same data is reachable directly at ebi.ac.uk/complexportal/ws; wrap it as a custom MCP server if you need programmatic access outside Claude Science.
What it does
Look up manually curated stable macromolecular complexes — subunit composition, stoichiometry, and function — from the Complex Portal (EMBL-EBI).
Primary use cases: Complex composition lookup, subunit/stoichiometry queries, interaction context
Notes
Claude Science: Offered inside Anthropic’s Claude Science via the Structures & Interactions featured connector. Its inclusion there is an independent signal of quality and trustworthiness for life-science research.
Data provider: EMBL-EBI Complex Portal (curated by the IntAct team). Bundled with PDB, AlphaFold DB, EMDB, and IntAct in Claude Science.
