AI agents call get_ga4gh_beacon to retrieve information from OrigeneMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves Beacon information (likely from GA4GH Beacon, a standard genomic data discovery system). It performs a read-only query operation with no side effects—no data is created, modified, deleted, or executed. The blast radius of misuse is minimal; an agent could only retrieve information about genomic variants or datasets.
From the tool's definition Tool name 'get_ga4gh_beacon' uses the verb 'get', indicating retrieval. Description 'Get Beacon information' confirms this is a query/retrieval operation with no indication of data modification, deletion, or execution of external operations.
Documented attack patterns abuse exactly the kind of access get_ga4gh_beacon gives an agent:
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 get_ga4gh_beacon:
{
"version": "1",
"default": "deny",
"tools": {
"get_ga4gh_beacon": {}
}
}get_ga4gh_beacon is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Get Beacon information. It is categorised as a Read tool in the OrigeneMCP MCP Server, which means it retrieves data without modifying state.
Register the Origene MCP server in PolicyLayer and add a rule for get_ga4gh_beacon: 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 OrigeneMCP. Nothing to install.
get_ga4gh_beacon 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 get_ga4gh_beacon 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 get_ga4gh_beacon. 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.
get_ga4gh_beacon is provided by the Origene MCP server (gentel-lab/origenemcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from OrigeneMCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
