AI agents call identify_scheme 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 performs analysis/classification by matching a claim to an existing argumentation scheme. It only reads and returns information about which scheme applies — no data is created, modified, deleted, or executed. The blast radius of misuse is minimal as it only affects the reasoning output, not any external systems.
From the tool's definition Identify which Walton argumentation scheme matches a claim
Attacks that exploit this kind of access
Identify which Walton argumentation scheme matches a claim. 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 identify_scheme: 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.
identify_scheme 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 identify_scheme 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 identify_scheme. 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.
identify_scheme 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.
