Why download_species_occurrences needs a policy

The tool name indicates a data retrieval operation fetching species occurrence records, typical of read-only GIS queries against biological datasets. While the description is empty (reducing confidence), the naming pattern and context within a GIS server that performs geometric operations and spatial analysis suggests this fetches pre-existing data rather than modifying, executing external code, deleting, or moving…

From the tool's definition Tool name 'download_species_occurrences' indicates retrieval of species occurrence data. No description provided, but the verb 'download' combined with the GIS server context suggests querying/fetching geospatial biodiversity data without modification or…

POLICY

How to control download_species_occurrences

PolicyLayer is an MCP gateway — it sits between your AI agents and GIS MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for download_species_occurrences:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "download_species_occurrences": {}
  }
}

download_species_occurrences is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register GIS MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
