Search INSPIRE Physics Literature
inspirehep/search-literature
Searches the INSPIRE high-energy physics literature database with INSPIRE query syntax (for example a witten and t duality, or arxiv:1602.03837), newest or most cited first: title, first 10 authors, arXiv id, DOIs, journal, citation count, and the abstract or keywords where the terms allow. Metadata from INSPIRE HEP, https://inspirehep.net, released under the CC0 waiver. E-mail addresses are not returned; abstracts are returned only when their source is arXiv or CERN, and keywords only where the INSPIRE terms allow. Modified by Eden Engine (fields renamed and reduced). Served by Eden Engine; not an official INSPIRE 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: "inspirehep/search-literature" })
// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "inspirehep/search-literature" })
// 4. run: price the exact call first, then run it
omnial_execute({ tool: "inspirehep/search-literature", input: { /* see input_schema */ }, dry_run: true })
omnial_execute({ tool: "inspirehep/search-literature", 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.
