ENA Study Search (Sequencing Projects by Taxon or Query)
enaportal/ena-search-studies
Searches the European Nucleotide Archive's public sequencing studies with ENA's query syntax, for example tax_eq(9606) for studies on taxon 9606 (Homo sapiens). Each study returns its accession, the submitter's description and a taxon id; up to 100 studies per call, with an offset for paging. Study descriptions are written by the submitters. European Nucleotide Archive data as served by Omnial, not an official 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 $5.
Data source
European Nucleotide Archive (EMBL-EBI)
Data from the European Nucleotide Archive (ENA), EMBL-EBI. Study descriptions are submitter-provided. Served by Eden Engine; not an official 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.
// 1. search: find the tool
omnial_search({ query: "what you need" })
// 2. inspect: price and input schema
omnial_inspect({ tool: "enaportal/ena-search-studies" })
// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "enaportal/ena-search-studies" })
// 4. run: price the exact call first, then run it
omnial_execute({ tool: "enaportal/ena-search-studies", input: { /* see input_schema */ }, dry_run: true })
omnial_execute({ tool: "enaportal/ena-search-studies", 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.
