Check if full text is available for a paper and get the open access URL if available.
AI agents call openalex_detect_fulltext 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 tool performs a lookup operation to determine availability and retrieve metadata (URL) about academic papers. It has no side effects, does not modify data, does not execute code or trigger external operations beyond simple data retrieval, and poses minimal risk if misused by an AI agent. It fits cleanly in the Read category as a search/query function.
From the tool's definition Tool name and description indicate it 'Check[s] if full text is available' and 'get[s] the open access URL' — purely informational operations that retrieve and query data without modifying, deleting, or executing code.
Attacks that exploit this kind of access
Check if full text is available for a paper and get the open access URL if available. 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 openalex_detect_fulltext: 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.
openalex_detect_fulltext 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 openalex_detect_fulltext 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 openalex_detect_fulltext. 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.
openalex_detect_fulltext is provided by the OpenAlex MCP Server MCP server (secretrichgarden/openalex-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
