EBI Proteins API

What is the EBI Proteins API MCP Server?

Connect to the EMBL-EBI Proteins API and access comprehensive protein biology data from one of the world's leading bioinformatics institutes.

What you can do

  • Protein Retrieval — Fetch complete protein entries by UniProt accession with names, organisms, gene information, sequences, and cross-references
  • Sequence Features — Retrieve annotated domains, binding sites, active sites, signal peptides, transmembrane regions, and disulfide bonds for any protein
  • Genetic Variants — Access curated variants from UniProtKB aggregated with large-scale studies including ClinVar, gnomAD, 1000 Genomes, COSMIC, and TOPMed
  • Proteomics & PTMs — Query mass-spectrometry peptide evidence and post-translational modifications from PeptideAtlas, MaxQB, EPD, and ProteomicsDB
  • Mutagenesis — Explore curated mutagenesis experiments with detailed phenotypic effect descriptions
  • Proteomes & Taxonomy — Search reference proteomes and navigate the taxonomy tree by ID or organism name
  • Genome Coordinates — Map proteins to genome positions on GRCh38/GRCh37 with Ensembl gene, transcript, and translation IDs

How it works

  1. Subscribe to this server
  2. No API key required — the EBI Proteins API is fully public
  3. Start querying protein data from Claude, Cursor, or any MCP-compatible client

Your AI agent becomes a molecular biology research assistant with direct access to the entire UniProt protein knowledge base. All data is sourced from the official EMBL-EBI Proteins REST API.

Who is this for?

  • Molecular Biologists — retrieve protein sequences, domain architectures, and functional annotations without navigating complex web databases
  • Clinical Geneticists — access aggregated variant data from ClinVar, gnomAD, and COSMIC for variant interpretation and pathogenicity assessment
  • Structural Biologists — query sequence features, binding sites, and mutagenesis data to guide experimental design
  • Bioinformaticians — programmatically access proteomes, taxonomy, and genome coordinate mappings for pipeline integration

search_taxonomy

Returns matching taxonomy entries with scientific names, common names, taxon IDs, and ranks. Useful for finding the correct taxon ID before querying proteins or proteomes for a specific organism. Search taxonomy by organism name

search_variation

g. large_scale_study, uniprot, mixed), consequence type (e.g. missense, stop gained), and wild-type residue. Use this to find clinically relevant variants across the proteome. Search variants by consequence type, source, or residue

Why Cline?

Cline operates autonomously inside VS Code. it reads your codebase, plans a strategy, and executes multi-step tasks including EBI Proteins API tool calls without waiting for prompts between steps. Connect 16 tools through Vinkius and Cline can fetch data, generate code, and commit changes in a single autonomous run.

  • Cline operates autonomously. it reads your codebase, plans a strategy, and executes multi-step tasks including MCP tool calls without step-by-step prompts

  • Runs inside VS Code, so you get MCP tool access alongside your existing extensions, terminal, and version control in a single window

  • Cline can create, edit, and delete files based on MCP tool responses, enabling end-to-end automation from data retrieval to code generation

  • Transparent execution: every tool call and file change is shown in Cline's activity log for full visibility and approval before committing

FAQ

Frequently asked questions

01

Do I need an API key to use this server?

No. The EMBL-EBI Proteins API is completely public and requires no authentication. Simply subscribe to this server and enter any placeholder value in the API key field to start querying protein data immediately.

02

What kind of variant data is available?

The server aggregates genetic variants from multiple authoritative sources: UniProtKB curated variants, ClinVar clinical significance data, gnomAD population frequencies, 1000 Genomes Project, COSMIC somatic mutations, TOPMed whole-genome sequencing, ExAC exome data, and TCGA cancer variants. Each variant includes consequence type, clinical significance, and source cross-references.

03

Can I map protein positions to genome coordinates?

Yes. The get_coordinates tool maps any UniProt protein to reference genome coordinates on GRCh38 and GRCh37 assemblies. It returns Ensembl gene, transcript, and translation identifiers along with chromosome, start/end positions, and strand orientation. This bridges the gap between protein-level annotations and genomic-level analyses.

04

How does Cline connect to MCP servers?

Cline reads MCP server configurations from its settings panel in VS Code. Add the server URL and Cline discovers all available tools on initialization.

05

Can Cline run MCP tools without approval?

By default, Cline asks for confirmation before executing tool calls. You can configure auto-approval rules for trusted servers in the settings.

06

Does Cline support multiple MCP servers at once?

Yes. Configure as many servers as needed. Cline can use tools from different servers within the same autonomous task execution.
