Attempt to read and extract text content from an OpenAIRE paper. Args: paper_id: OpenAIRE paper identifier. save_path: Directory where the PDF is/will be saved (default: './downloads'). Returns: str: Extracted text or error message.
AI agents call read_openaire_paper to retrieve information from Paper Search MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries data from OpenAIRE without creating, modifying, deleting, or executing arbitrary operations. The blast radius of misuse is minimal—an AI agent could retrieve unwanted papers but cannot alter systems, execute code, or cause financial harm. Classified as Read with low severity.
From the tool's definition Tool performs text extraction from academic papers ('read and extract text content'). The description explicitly states it returns 'Extracted text or error message' with no modification or deletion capabilities.

PolicyLayer is an MCP gateway — it sits between your AI agents and Paper Search MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for read_openaire_paper:
{
"version": "1",
"default": "deny",
"tools": {
"read_openaire_paper": {}
}
}read_openaire_paper is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Returns: str: Extracted text or error message. It is categorised as a Read tool in the Paper Search MCP MCP Server, which means it retrieves data without modifying state.
Register the Paper Search MCP server in PolicyLayer and add a rule for read_openaire_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 Paper Search MCP. Nothing to install.
read_openaire_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 read_openaire_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 read_openaire_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.
read_openaire_paper is provided by the Paper Search MCP server (openags/paper-search-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
