WHAT IT DOES

What post_ga4gh_beacon_query does on OrigeneMCP

AI agents call post_ga4gh_beacon_query to retrieve information from OrigeneMCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why post_ga4gh_beacon_query is rated Low

GA4GH Beacon is a standard protocol for querying genomic variant availability across databases. Despite using POST, the operation is a read/search that retrieves information about genomic variants. No data is created, modified, or deleted. Severity is low as it only retrieves publicly discoverable genomic data.

From the tool's definition 'Query Beacon with POST' — the tool queries a GA4GH Beacon endpoint (a genomic data discovery API) using HTTP POST; POST is used here as a query mechanism, not for data creation
