AI agents call smithsonian_get_object to retrieve information from Smithsonian 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 smithsonian_get_object 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.

Fetch the full catalog record for a Smithsonian object by its record_id (from smithsonian_search results). Returns all available metadata: title, dates, materials, dimensions, provenance, exhibition history, credit line, accession identifiers, and a media summary. Call smithsonian_get_media for full image URLs. Use record_id values from smithsonian_search — do not manually construct IDs.. It is categorised as a Read tool in the Smithsonian Mcp Server MCP Server, which means it retrieves data without modifying state.
Register the Smithsonian Mcp Server MCP server in PolicyLayer and add a rule for smithsonian_get_object: 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 Smithsonian Mcp Server. Nothing to install.
smithsonian_get_object 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 smithsonian_get_object 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 smithsonian_get_object. 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.
smithsonian_get_object is provided by the Smithsonian Mcp Server MCP server (@cyanheads/smithsonian-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
