AI agents call score_arguments to retrieve information from Warrant without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool computes scores/rankings for arguments using gradual semantics, which is a read/analytical operation. It processes existing argument data and returns computed scores without modifying, deleting, or executing anything. The blast radius is low since misuse would only produce incorrect analysis, not data loss or system changes.

Attacks that exploit this kind of access
Score arguments using gradual semantics. It is categorised as a Read tool in the Warrant MCP Server, which means it retrieves data without modifying state.
Register the Warrant MCP server in PolicyLayer and add a rule for score_arguments: 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 Warrant. Nothing to install.
score_arguments 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 score_arguments 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 score_arguments. 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.
score_arguments is provided by the Warrant MCP server (jayden-chmod/warrant-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
