AI agents call lookup_tafsirs to retrieve information from Tarteel 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 lookup_tafsirs 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 lookup_tafsirs gives an agent. Each links to the full case and the policy that stops it:
Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
INTERNAL/preparatory tool — text-only, no widget rendered. NEVER use as the user-facing answer to a 'what tafsirs are supported' question — use list_tafsirs for that (the default interactive widget). Use this ONLY when EITHER (a) the user explicitly asks for plain text / raw data / no widget, OR (b) you will chain the result into ayah_tafsir in the same turn without showing the raw list (e.g. resolve a named tafsir to its slug, then call ayah_tafsir). When in doubt, prefer list_tafsirs.. It is categorised as a Read tool in the Tarteel MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Tarteel MCP Server MCP server in PolicyLayer and add a rule for lookup_tafsirs: 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 Tarteel MCP Server. Nothing to install.
lookup_tafsirs 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 lookup_tafsirs 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 lookup_tafsirs. 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.
lookup_tafsirs is provided by the Tarteel MCP Server MCP server (https://mcp.tarteel.ai/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
