Run the openalex search engine with a given query, retrieving and filtering results.
AI agents call paper_search to retrieve information from OrigeneMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves academic paper metadata from OpenAlex, a public database. It performs a search query and filters results—purely informational operations with no ability to modify data, execute code, delete records, or trigger external state changes. It aligns with the 'Read' category of tools that retrieve or query data without side effects.
From the tool's definition Tool name 'paper_search' and description 'Run the openalex search engine with a given query, retrieving and filtering results' indicate read-only data retrieval.
Documented attack patterns abuse exactly the kind of access paper_search gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and OrigeneMCP, and nothing reaches the server without passing your rules. This is the rule we recommend for paper_search:
{
"version": "1",
"default": "deny",
"tools": {
"paper_search": {}
}
}paper_search is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Run the openalex search engine with a given query, retrieving and filtering results. It is categorised as a Read tool in the OrigeneMCP MCP Server, which means it retrieves data without modifying state.
Register the Origene MCP server in PolicyLayer and add a rule for paper_search: 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 OrigeneMCP. Nothing to install.
paper_search 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 paper_search 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 paper_search. 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.
paper_search is provided by the Origene MCP server (gentel-lab/origenemcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from OrigeneMCP, 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.
