Query Europe PMC to retrieve real, peer-reviewed papers matching a biological query.
AI agents call search_literature to retrieve information from BioCite-MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a search query against Europe PMC to return matching academic papers. It retrieves and presents existing data without creating, modifying, deleting, or executing any operations. The blast radius of misuse is minimal—an agent could retrieve irrelevant papers or conduct excessive queries, but no data is at risk and no external actions are triggered. This is a straightforward Read operation.
From the tool's definition Tool description states it 'retrieves' papers and 'query' Europe PMC, with no mention of modification, execution, or deletion. The verb 'retrieve' and the read-only nature of querying a literature database clearly indicate data retrieval only.
Attacks that exploit this kind of access
Query Europe PMC to retrieve real, peer-reviewed papers matching a biological query. It is categorised as a Read tool in the BioCite-MCP MCP Server, which means it retrieves data without modifying state.
Register the BioCite- MCP server in PolicyLayer and add a rule for search_literature: 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 BioCite-MCP. Nothing to install.
search_literature 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_literature 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_literature. 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_literature is provided by the BioCite- MCP server (muslus/biocite-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
