AI agents call get_gene_info to retrieve information from Oh My KEGG MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a query operation on the KEGG database to retrieve and return information about a gene. It has no side effects, does not modify data, does not execute code or commands, and does not involve financial transactions. It is a straightforward read operation that fetches existing data from a biological database.
From the tool's definition Tool name 'get_gene_info' and description 'Get detailed information for a specific gene' indicate data retrieval with no modification, deletion, or execution of external operations.
Documented attack patterns abuse exactly the kind of access get_gene_info gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Oh My KEGG MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for get_gene_info:
{
"version": "1",
"default": "deny",
"tools": {
"get_gene_info": {}
}
}get_gene_info 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 detailed information for a specific gene. It is categorised as a Read tool in the Oh My KEGG MCP MCP Server, which means it retrieves data without modifying state.
Register the Oh My KEGG MCP server in PolicyLayer and add a rule for get_gene_info: 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 Oh My KEGG MCP. Nothing to install.
get_gene_info 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_gene_info 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_gene_info. 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_gene_info is provided by the Oh My KEGG MCP server (martinuslee/oh-my-kegg-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Oh My KEGG MCP, 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.
