Search for medical research articles in PubMed
AI agents call search-medical-literature to retrieve information from Medical without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information from PubMed without modifying, deleting, or executing code. It is a straightforward search/query function that returns medical research data. No irreversible changes, code execution, or financial operations are involved. The risk is minimal as misuse would only retrieve existing medical literature, not alter systems or data.
From the tool's definition Tool description states it 'Search[es] for medical research articles in PubMed' — a query operation with no side effects. The verb 'search' and read-only nature of querying a medical literature database confirm retrieval-only functionality.
Documented attack patterns abuse exactly the kind of access search-medical-literature gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Medical, and nothing reaches the server without passing your rules. This is the rule we recommend for search-medical-literature:
{
"version": "1",
"default": "deny",
"tools": {
"search-medical-literature": {}
}
}search-medical-literature 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.
Search for medical research articles in PubMed. It is categorised as a Read tool in the Medical MCP Server, which means it retrieves data without modifying state.
Register the Medical MCP server in PolicyLayer and add a rule for search-medical-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 Medical. Nothing to install.
search-medical-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 search-medical-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 search-medical-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.
search-medical-literature is provided by the Medical MCP server (jamesanz/medical-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Medical, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
