Itis Tools (3)
search_taxa
Search ITIS (authoritative US-government integrated taxonomy for plants, animals, fungi, and microbes) by scientific name and resolve it to TSNs (Taxonomic Serial Numbers). Returns matching taxa with tsn, scientific name, author, and kingdom. Keyless. Use the tsn with get_hierarchy or get_common_na…
get_hierarchy
Walk the full taxonomic hierarchy (lineage) for a TSN from ITIS — kingdom down to the taxon and its children. Returns each rank with its tsn, name, rank, and parent_tsn. Pass a TSN from search_taxa. Keyless.
get_common_names
Get vernacular (common) names in all languages for a TSN from ITIS, e.g. "Bobcat", "lynx roux". Pass a TSN from search_taxa. Keyless.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Obis is categorized under Developer Tools and uses a remote streaming HTTP/SSE transport. In contrast, Itis belongs to Developer Tools using remote streaming HTTP/SSE transport. Select Obis when you need capabilities focused on developer tools and Itis when you require tools for developer tools.
