Why post_ga4gh_features_search needs a policy

The description is empty, so classification is based solely on the name. 'post_ga4gh_features_search' likely performs a search/query operation against GA4GH genomic feature data (a Read operation), but the HTTP POST method and 'features_search' phrasing could imply query execution with side effects.

From the tool's definition Tool name: post_ga4gh_features_search — description is empty/uninformative. The name suggests a GA4GH (Global Alliance for Genomics and Health) features search operation.

How to control post_ga4gh_features_search

PolicyLayer is an MCP gateway — it sits between your AI agents and OrigeneMCP, and nothing reaches the server without passing your rules. This is the rule we recommend for post_ga4gh_features_search:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "post_ga4gh_features_search": {
      "limits": [
        {
          "counter": "post_ga4gh_features_search_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

post_ga4gh_features_search gets a rate cap, and everything else on the server is denied unless you say otherwise.
