AI agents call list_bib_resources to retrieve information from Eff without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only retrieval operation that lists bibliographic resources. The action is informational only—it queries and returns BibTeX metadata without creating, modifying, deleting, or executing any operations. Within the ethics analysis framework context, listing bibliography resources poses minimal risk.
From the tool's definition Tool lists BibTeX entries and provides metadata retrieval (list_*, search_* family on ethics framework server); no modification, deletion, or execution capabilities described.
Attacks that exploit this kind of access
List all BibTeX entries as MCP resources with minimal metadata. It is categorised as a Read tool in the Eff MCP Server, which means it retrieves data without modifying state.
Register the Eff MCP server in PolicyLayer and add a rule for list_bib_resources: 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 Eff. Nothing to install.
list_bib_resources 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 list_bib_resources 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 list_bib_resources. 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.
list_bib_resources is provided by the Eff MCP server (vs3kulic/eff-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
