AI agents call courtlistener_get_citations to retrieve information from Courtlistener Mcp Server without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though courtlistener_get_citations only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Retrieve the citation network for an opinion cluster. Supports two directions: "cited_by" (opinions that cite this one — measures precedential influence) and "citing" (opinions this one cites — reveals the authority chain relied on). This is the primary tool for tracing legal precedent chains. Note: the free tier (125 req/day) supports shallow traversal — following 1–2 hops of a single case is practical; deep multi-hop analysis burns through the daily budget quickly.. 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 courtlistener_get_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.
courtlistener_get_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 courtlistener_get_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 courtlistener_get_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.
courtlistener_get_citations is provided by the Courtlistener Mcp Server MCP server (@cyanheads/courtlistener-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
