AI agents call get_gene_literature 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.
This tool retrieves gene-related literature from academic databases without modifying, deleting, or executing arbitrary code. It is a read operation with no side effects. Severity is low because misuse would only expose research data already intended for academic access. Confidence is moderate-high due to empty description, but context from server purpose and naming convention supports the Read classification.
From the tool's definition Tool name 'get_gene_literature' indicates retrieval of literature data about genes. Description is empty, but the server is explicitly described as providing 'literature search and analysis across multiple academic databases', and the sibling tools…

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_literature:
{
"version": "1",
"default": "deny",
"tools": {
"get_gene_literature": {}
}
}get_gene_literature is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_gene_literature. 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_literature: 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_literature 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_literature 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_literature. 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_literature 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.
