Southern California Earthquake Catalogue Search (SCEDC)
scedcfdsn/earthquake-search
Search the Southern California Seismic Network earthquake catalogue (Caltech and the U.S. Geological Survey) by time window, magnitude range and optional latitude-longitude box. Returns up to 200 events with origin time, location, depth, magnitude and nearest town, newest first or largest first. A window with no events returns an empty list. Data from the Southern California Earthquake Data Center (SCEDC), passed through and served by Eden Engine; not an official SCEDC or Caltech 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: "scedcfdsn/earthquake-search" })
// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "scedcfdsn/earthquake-search" })
// 4. run: price the exact call first, then run it
omnial_execute({ tool: "scedcfdsn/earthquake-search", input: { /* see input_schema */ }, dry_run: true })
omnial_execute({ tool: "scedcfdsn/earthquake-search", 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.
