AI agents call search_alexandria to retrieve information from Intelligence Aeternum 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 search_alexandria 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.

FREE — Search 2M+ museum artworks in the Alexandria Aeternum catalog. Searches the Firestore manifest (primary) with Vertex AI fallback. Returns artifact IDs, titles, artists, dates, and classification. Use get_curated_metadata() for Human_Standard metadata + image (5 free/day). Use get_oracle_metadata() for Hybrid_Premium VLM deep analysis + image. Args: query: Free-text search (e.g., "impressionist landscape", "Rembrandt portrait"). museum: Filter by museum: met, nga, chicago, cleveland, rijksmuseum, smithsonian, paris. limit: Max results (default 20, max 100).. It is categorised as a Read tool in the Intelligence Aeternum MCP Server, which means it retrieves data without modifying state.
Register the Intelligence Aeternum MCP server in PolicyLayer and add a rule for search_alexandria: 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 Intelligence Aeternum. Nothing to install.
search_alexandria 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 search_alexandria 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 search_alexandria. 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.
search_alexandria is provided by the Intelligence Aeternum MCP server (https://data-portal-172867820131.us-west1.run.app/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
