Search for papers in ArXiv (alias for search_arxiv).
AI agents call search_paper to retrieve information from UniArticles MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool searches an academic database and returns results. This is a classic Read operation with no side effects, no code execution, no data modification, and no destructive capabilities. Severity is low because misuse poses minimal risk — a malicious agent could retrieve excessive search results but cannot modify data, execute code, move funds, or cause other harm through this interface.
From the tool's definition Tool name 'search_paper' described as 'Search for papers in ArXiv' — a query operation that retrieves metadata without modification.
Documented attack patterns abuse exactly the kind of access search_paper gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and UniArticles MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for search_paper:
{
"version": "1",
"default": "deny",
"tools": {
"search_paper": {}
}
}search_paper is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Search for papers in ArXiv (alias for search_arxiv). It is categorised as a Read tool in the UniArticles MCP Server MCP Server, which means it retrieves data without modifying state.
Register the UniArticles MCP Server MCP server in PolicyLayer and add a rule for search_paper: 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 UniArticles MCP Server. Nothing to install.
search_paper 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_paper 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_paper. 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_paper is provided by the UniArticles MCP Server MCP server (thinktraveller/uniarticles_mcpserver). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from UniArticles MCP Server, 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.
