WHAT IT DOES

What search_by_subject does on CLIO Adios

AI agents call search_by_subject to retrieve information from CLIO Adios without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why search_by_subject is rated Low

This tool retrieves or queries academic papers from ArXiv based on subject filters. It performs a read-only search operation with no ability to modify, delete, or execute code. The blast radius of misuse is minimal—an agent could only retrieve papers it shouldn't have access to, which poses no operational risk.

From the tool's definition Tool name 'search_by_subject' and description 'Search ArXiv papers by subject classification' indicate a query operation with no side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs search_by_subject safely

PolicyLayer is an MCP gateway: it sits between your AI agents and CLIO Adios, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For search_by_subject, this is the rule to start with:

search_by_subject Allowed

search_by_subject is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "search_by_subject": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect CLIO Adios, apply this rule, and every search_by_subject call is checked against it from then on.
