UniProt Protein Entry Lookup
proteins/protein-lookup
UniProtKB entry for one accession (for example P04637, P01308, P02144) from the EMBL-EBI Proteins API: entry type (reviewed or not), names, gene, organism and lineage, evidence level, keywords, the full amino-acid sequence with length and mass, and annotation comments (function, subunit, subcellular location, tissue specificity, disease, post-translational modification and more) as plain text. Features, literature references and cross-references are reduced to counts; use protein-features for features. UniProt data, served by Eden Engine; not an official UniProt or EMBL-EBI product.

Price
$0.0026 per call
You pay the price shown. If a call turns out to cost more than its quote, you pay the actual price, capped at twice the quote. No monthly minimum. Top-ups start at $0.50.
Data source
Data from UniProt (UniProt Consortium), served by the EMBL-EBI Proteins API (https://www.ebi.ac.uk/proteins/api). Cite: The proteins API: accessing key integrated protein and genome information, doi:10.1093/nar/gkx237. Served by Eden Engine; not an official UniProt or EMBL-EBI product.
Use it
Five steps: search, inspect, learn, run, settle. No per-tool setup; your agent reaches this tool through the meta-tools it already has.
Connect once and your AI can find and run this tool, and any other it needs.
agent
// 1. search: find the tool
omnial_search({ query: "what you need" })
// 2. inspect: price and input schema
omnial_inspect({ tool: "proteins/protein-lookup" })
// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "proteins/protein-lookup" })
// 4. run: price the exact call first, then run it
omnial_execute({ tool: "proteins/protein-lookup", input: { /* see input_schema */ }, dry_run: true })
omnial_execute({ tool: "proteins/protein-lookup", input: { /* ... */ } })
// 5. settle: the call is charged when it finishes, nothing to doNot connected yet? Point your MCP client at https://mcp.eden-engine.com/mcp, then copy a config for your client.
