verify_citations
AI agents call verify_citations to retrieve information from CourtListener MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Citation verification is fundamentally a lookup/query operation that checks and retrieves information about citations in legal documents. No modifications, deletions, or side effects are indicated. Even with an empty description, the tool name and ecosystem of sibling Read-category tools provide high confidence this is a retrieval operation. Lowest severity applies to read-only queries.
From the tool's definition Tool name 'verify_citations' indicates citation verification/lookup; sibling tools like 'find_authorities_cited', 'find_citing_opinions', and 'analyze_citation_network' are all Read operations querying legal database relationships.
Attacks that exploit this kind of access
verify_citations. It is categorised as a Read tool in the CourtListener MCP Server MCP Server, which means it retrieves data without modifying state.
Register the CourtListener MCP Server MCP server in PolicyLayer and add a rule for verify_citations: 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 CourtListener MCP Server. Nothing to install.
verify_citations 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 verify_citations 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 verify_citations. 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.
verify_citations is provided by the CourtListener MCP Server MCP server (upsd1/courtlistener-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
