Get detailed information about a gene by NCBI Gene ID.
AI agents call get_gene_details to retrieve information from Pubmed Search without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and returns reference data about genes from NCBI databases. It performs no side effects, creates no data, modifies nothing, executes no arbitrary code, and deletes nothing. This is a straightforward read operation with minimal risk even if misused by an AI agent—the worst outcome would be fetching irrelevant gene information.
From the tool's definition Tool name 'get_gene_details' and description 'Get detailed information about a gene by NCBI Gene ID' indicate retrieval of existing gene data without modification or deletion. This is a query/lookup operation.

PolicyLayer is an MCP gateway — it sits between your AI agents and Pubmed Search, and nothing reaches the server without passing your rules. This is the rule we recommend for get_gene_details:
{
"version": "1",
"default": "deny",
"tools": {
"get_gene_details": {}
}
}get_gene_details is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get detailed information about a gene by NCBI Gene ID. It is categorised as a Read tool in the Pubmed Search MCP Server, which means it retrieves data without modifying state.
Register the Pubmed Search MCP server in PolicyLayer and add a rule for get_gene_details: 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 Pubmed Search. Nothing to install.
get_gene_details 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_details 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_details. 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_details is provided by the Pubmed Search MCP server (u9401066/pubmed-search-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Pubmed Search, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
