Tools

neon-mcp exposes 20 tools (19 over HTTP, where downloads are not offered). Start with the generated Tool reference for exact inputs and result fields; the family pages explain when to use which tool and what to watch for.

  • Tool reference - Every tool with its inputs, result fields, NEON endpoints, token requirement and annotations, generated from the registry.
  • Products - Find data products by keywords, theme or team, read a product in depth, and navigate its opt-in detail sections.
  • Sites - Find NEON field sites by name, state, domain, product or proximity, and read one site with its products.
  • Locations - Walk site, domain and REALM hierarchies by location type (towers, plots, huts) and read one location in depth.
  • Availability and data files - Check which sites and months have data, list data files with signed URLs, and download them safely on stdio.
  • Releases and citations - Browse NEON's annual releases and DOIs, read one release, and produce correct citations.
  • Taxonomy - Page through NEON taxon lists by type code or rank, with exact-name matching and a genus fallback.
  • Samples - Look up sample classes and a physical sample's custody chain, including the one multi-round-trip tool.
  • Prototype datasets - Search NEON's prototype datasets and read one with its files, DOI and descriptions.
  • GraphQL - The guard-railed read-only GraphQL tool for shapes the dedicated tools do not cover.
  • Utilities and errors - Status checks, NEON documents (ATBDs, protocols) and the error codes every tool can return.
  • Resources and prompts - The neon:// guides and references, the three resource templates, and the three prompts.
