What is the EBI InterPro MCP Server?
Connect to the InterPro API and access the world's most comprehensive resource for protein family, domain, and functional site classification.
What you can do
- Domain Classification — Retrieve detailed InterPro entry information including family/domain descriptions, GO terms, and member database cross-references
- Multi-Database Access — Query entries from Pfam, CDD, SMART, Prosite, PANTHER, Gene3D, HAMAP, and more through a unified interface
- Protein Annotation — Find all InterPro domains, families, and sites annotated on any UniProt protein
- Structure Mapping — Discover PDB structures containing proteins that match specific InterPro entries
- Taxonomic Distribution — Explore which organisms contain proteins matching a domain or family — essential for evolutionary biology
- Proteome Coverage — Assess domain annotation coverage for complete proteomes
- Clan Analysis — Navigate Pfam clan hierarchies to understand super-family relationships
How it works
- Subscribe to this server
- No API key required — the InterPro API is fully public
- Start classifying proteins from Claude, Cursor, or any MCP-compatible client
Your AI agent becomes a protein domain expert with access to InterPro's unified classification of protein families from 13+ member databases. All data is sourced from the official InterPro REST API maintained by EMBL-EBI.
Who is this for?
- Molecular Biologists — classify unknown proteins into families and predict their functional domains
- Evolutionary Biologists — explore taxonomic distributions of protein domains across the tree of life
- Structural Biologists — find 3D structures containing specific protein domains for comparative analysis
- Bioinformaticians — integrate protein family classifications into automated annotation pipelines

Shows the number of entries in each database. Useful for understanding the scope of available domain and family annotations. List all InterPro member databases and entry counts
Optionally filter by entry type: family, domain, homologous_superfamily, repeat, or site. Returns accessions, names, types, and protein/structure counts. Use queries like "kinase", "zinc finger", "immunoglobulin". Search InterPro entries by keyword and type
Returns UniProt accessions, names, lengths, organisms, and annotation counts. Use queries like "insulin", "hemoglobin", "BRCA1". Search proteins in InterPro by name or keyword
Returns taxon IDs, names, ranks, and annotation counts. Use queries like "human", "drosophila", "arabidopsis", "saccharomyces". Search taxonomy by organism name

Frequently asked questions
Do I need an API key?
No. The InterPro API is completely public and requires no authentication. Enter any placeholder value in the API key field to activate the server immediately.
What databases does InterPro integrate?
InterPro integrates 13+ member databases including Pfam (protein families), CDD (conserved domains from NCBI), SMART (signalling domains), Prosite (patterns and profiles), PANTHER (evolutionary classification), Gene3D (structural domains from CATH), HAMAP (microbial families), PRINTS (fingerprints), PIRSF (classification system), SFLD (superfamilies), and NCBIfam. This gives you a unified view of protein domain and family annotations from the world's leading classification resources.
Can I find which organisms have a specific protein domain?
Yes. Use the get_entry_taxonomy tool with any InterPro accession to see the taxonomic distribution of that domain or family. This shows which organisms — from bacteria to humans — contain proteins with that specific domain. It is one of the most powerful tools for evolutionary biology, revealing how protein domains have been conserved or diversified across the tree of life.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
