AI agents call gbif_search_occurrences to retrieve information from Gbif Biodiversity Mcp Server without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though gbif_search_occurrences only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

These attack patterns abuse exactly the kind of access gbif_search_occurrences gives an agent. Each links to the full case and the policy that stops it:
Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Search 2.4B+ GBIF occurrence records with Darwin Core filters. Use taxonKey from gbif_match_species for reliable results — it resolves synonyms automatically. Accepts country (ISO 3166-1 alpha-2), bounding box (decimalLatitude/decimalLongitude ranges), WKT polygon geometry, year range, month, basis of record, and coordinate filter. Pagination is capped at approximately offset+limit=100,000 — use gbif_occurrence_facets for aggregate counts across large result sets.. It is categorised as a Read tool in the Gbif Biodiversity Mcp Server MCP Server, which means it retrieves data without modifying state.
Register the Gbif Biodiversity Mcp Server MCP server in PolicyLayer and add a rule for gbif_search_occurrences: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Gbif Biodiversity Mcp Server. Nothing to install.
gbif_search_occurrences is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the gbif_search_occurrences rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for gbif_search_occurrences. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
gbif_search_occurrences is provided by the Gbif Biodiversity Mcp Server MCP server (@cyanheads/gbif-biodiversity-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
