Gene Lookup by Symbol (Bgee)

bgeesparql/gene-lookup

Looks up genes in the Bgee knowledge graph by exact gene symbol (case sensitive, for example INS or Tp53) and returns one row per gene with its Bgee gene IRI, its identifier and the species IRI (https://bgee.org/species/<NCBI taxon id>), up to `limit` rows (default 25, at most 100). Bgee data, passed through unmodified and served by Eden Engine; not an official Bgee 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: "bgeesparql/gene-lookup" })

// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "bgeesparql/gene-lookup" })

// 4. run: price the exact call first, then run it
omnial_execute({ tool: "bgeesparql/gene-lookup", input: { /* see input_schema */ }, dry_run: true })
omnial_execute({ tool: "bgeesparql/gene-lookup", input: { /* ... */ } })

// 5. settle: the call is charged when it finishes, nothing to do
