AI agents call met_list_departments to retrieve information from Met Museum 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 met_list_departments 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.

Return the 19 curatorial departments at The Metropolitan Museum of Art with their numeric IDs and display names. Use before calling met_search to discover valid departmentId values. The department list is fetched live on each call to remain accurate if the Met reorganizes.. It is categorised as a Read tool in the Met Museum Mcp Server MCP Server, which means it retrieves data without modifying state.
Register the Met Museum Mcp Server MCP server in PolicyLayer and add a rule for met_list_departments: 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 Met Museum Mcp Server. Nothing to install.
met_list_departments 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 met_list_departments 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 met_list_departments. 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.
met_list_departments is provided by the Met Museum Mcp Server MCP server (@cyanheads/met-museum-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
