Return an agent-guided PICO schema for a clinical question.
AI agents call analyze_clinical_question 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 or structures information from a provided clinical question to generate a schema—a classic read operation with no side effects. It does not create, modify, delete, execute external operations, or commit financial obligations. The naming convention ('analyze') and function ('return schema') confirm it is purely informational retrieval/transformation.
From the tool's definition Tool description states it 'Return[s] an agent-guided PICO schema', which indicates data retrieval and analysis without modification.
Documented attack patterns abuse exactly the kind of access analyze_clinical_question gives an agent:
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 analyze_clinical_question:
{
"version": "1",
"default": "deny",
"tools": {
"analyze_clinical_question": {}
}
}analyze_clinical_question is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Return an agent-guided PICO schema for a clinical question. 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 analyze_clinical_question: 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.
analyze_clinical_question 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 analyze_clinical_question 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 analyze_clinical_question. 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.
analyze_clinical_question 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.
Free to start. No card required.
