AI agents call originators_like to retrieve information from Quotewise 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 originators_like 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.

Find originators similar to the given one using vector similarity (quote themes). Use after finding an author to discover related thinkers. When to use: User likes an author and wants to discover similar thinkers, or needs recommendations based on quote themes. Returns originators with similarity scores (0-100%). Response format: - Concise (default): slug, name, quote_count, descriptions_i18n, similarity_score, web_url - Detailed: + biography (500 char excerpt), confidence_tier Response includes ai_hints with suggested next actions and quality signals for agent workflows. Examples: - originators_like(originator="Marcus Aurelius") - similar philosophers - originators_like(originator="Oscar Wilde") - similar wits - originators_like(originator="African Proverbs") - similar proverb collections. It is categorised as a Read tool in the Quotewise MCP Server, which means it retrieves data without modifying state.
Register the Quotewise MCP server in PolicyLayer and add a rule for originators_like: 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 Quotewise. Nothing to install.
originators_like 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 originators_like 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 originators_like. 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.
originators_like is provided by the Quotewise MCP server (https://mcp.quotewise.io/). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
