string_query_species
shalloworg.string-db/string-mcp · Verify this server
Search for species or clades available in STRING by free-text query and return their NCBI taxonomy IDs. - Use this when the user asks which species or clades are present in STRING, or when you need the correct NCBI taxon ID to pass to other tools. - use this to resolve NCBI taxons IDs to their scientific names. - Accepts up to 100 taxon IDs separated by `%0d`. - The results are limited to the top 50 matches per query. - When the user asks for a species list, do not list clades. - If the requested species cannot be matched (i.e. the correct species is not present in the results), **immediately invoke the 'string_help' tool with topic='missing_species'**.
