AI agents call get_subjects to retrieve information from Makuri Showcase (CogniLedger) 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 get_subjects 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.

These attack patterns abuse exactly the kind of access get_subjects gives an agent. Each links to the full case and the policy that stops it:

Returns the list of academic subjects Makuri teaches, grouped by grade level, with information about exam preparation coverage. Use when the user asks what Makuri teaches or about specific subjects.. It is categorised as a Read tool in the Makuri Showcase (CogniLedger) MCP Server, which means it retrieves data without modifying state.
Register the Makuri Showcase (CogniLedger) MCP server in PolicyLayer and add a rule for get_subjects: 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 Makuri Showcase (CogniLedger). Nothing to install.
get_subjects 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 get_subjects 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 get_subjects. 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.
get_subjects is provided by the Makuri Showcase (CogniLedger) MCP server (https://mcp.cogniledger.eu/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
