Analyze publication trends over time for specific topics or queries. Returns works grouped by year to show research evolution and growth.
AI agents call analyze_topic_trends to retrieve information from OpenAlex Research MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Even though analyze_topic_trends only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Documented attack patterns abuse exactly the kind of access analyze_topic_trends gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and OpenAlex Research MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for analyze_topic_trends:
{
"version": "1",
"default": "deny",
"tools": {
"analyze_topic_trends": {}
}
}analyze_topic_trends is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Analyze publication trends over time for specific topics or queries. Returns works grouped by year to show research evolution and growth. It is categorised as a Read tool in the OpenAlex Research MCP Server MCP Server, which means it retrieves data without modifying state.
Register the OpenAlex Research MCP Server MCP server in PolicyLayer and add a rule for analyze_topic_trends: 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 OpenAlex Research MCP Server. Nothing to install.
analyze_topic_trends 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_topic_trends 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_topic_trends. 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_topic_trends is provided by the OpenAlex Research MCP Server MCP server (oksure/openalex-research-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
