AI agents call ebird_get_taxonomy to retrieve information from eBird MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves taxonomic data from the eBird database without creating, modifying, deleting, or executing any operations. The 'get' verb and read-only nature of taxonomy lookups classify this as a Read operation with minimal risk. No side effects or blast radius beyond returning potentially unwanted information.
From the tool's definition Tool name 'ebird_get_taxonomy' and description 'Get eBird taxonomy information' indicate a retrieval operation with no modification or execution of external code.

{
"version": "1",
"default": "deny",
"tools": {
"ebird_get_taxonomy": {}
}
} ebird_get_taxonomy is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
