Search research topics (formerly concepts)
AI agents call search_topics to retrieve information from OpenAlex MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only search tool that queries existing research topics in the OpenAlex database. It retrieves information without creating, modifying, deleting, or executing any operations. The blast radius of misuse is minimal—an agent could perform excessive searches or retrieve unexpected data, but cannot harm the system or data integrity.
From the tool's definition Tool name 'search_topics' and description 'Search research topics (formerly concepts)' indicate a search/query operation that retrieves topic data from OpenAlex's catalog without modification or side effects.
Attacks that exploit this kind of access
Search research topics (formerly concepts). It is categorised as a Read tool in the OpenAlex MCP Server MCP Server, which means it retrieves data without modifying state.
Register the OpenAlex MCP Server MCP server in PolicyLayer and add a rule for search_topics: 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 MCP Server. Nothing to install.
search_topics 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_topics 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_topics. 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_topics is provided by the OpenAlex MCP Server MCP server (reetp14/openalex-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
