AI agents call proximens_oracle_search_principles to retrieve information from Proximens Oracle 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 proximens_oracle_search_principles 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.

Semantic search over the Proximens GEO Oracle — a curated knowledge-base of 458+ Generative Engine Optimization principles distilled from research papers, vendor documentation, and patents. Free tier returns top-5 summaries; Pro tier returns top-25 with full text, source URLs, and confidence scores. Use this when you need authoritative answers about how AI search engines (ChatGPT, Perplexity, Gemini, Copilot) evaluate and cite content.. It is categorised as a Read tool in the Proximens Oracle MCP Server, which means it retrieves data without modifying state.
Register the Proximens Oracle MCP server in PolicyLayer and add a rule for proximens_oracle_search_principles: 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 Proximens Oracle. Nothing to install.
proximens_oracle_search_principles 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 proximens_oracle_search_principles 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 proximens_oracle_search_principles. 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.
proximens_oracle_search_principles is provided by the Proximens Oracle MCP server (https://www.proximens.nl/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
