AI agents call search_all to retrieve information from Legal without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool searches and retrieves case law data from CourtListener API without modifying, deleting, or executing external operations. It is a pure query/retrieval function with no side effects on the data or systems. Low severity because even if misused by an AI agent, the blast radius is limited to accessing publicly available legal information.
From the tool's definition Tool name 'search_all' and description 'Aggregated case-law search across every configured' indicate data retrieval/querying operation.

Attacks that exploit this kind of access
Aggregated case-law search across every configured. It is categorised as a Read tool in the Legal MCP Server, which means it retrieves data without modifying state.
Register the Legal MCP server in PolicyLayer and add a rule for search_all: 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 Legal. Nothing to install.
search_all 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_all 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_all. 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_all is provided by the Legal MCP server (mcpservings/legal-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
