Calculate the exact diversity penalty for a specific post position using the author_diversity_scorer.rs formula.
AI agents call diversity_penalty to retrieve information from X Algorithm Toolkit without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or calculates data without side effects. It analyzes a post's diversity penalty score using X's algorithm weights but does not create, modify, delete, or execute code/commands. The output is informational only, making it a Read operation with low severity.
From the tool's definition Tool name 'diversity_penalty' and description 'Calculate the exact diversity penalty' indicates a calculation/retrieval operation.
Attacks that exploit this kind of access
Calculate the exact diversity penalty for a specific post position using the author_diversity_scorer.rs formula. It is categorised as a Read tool in the X Algorithm Toolkit MCP Server, which means it retrieves data without modifying state.
Register the X Algorithm Toolkit MCP server in PolicyLayer and add a rule for diversity_penalty: 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 X Algorithm Toolkit. Nothing to install.
diversity_penalty 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 diversity_penalty 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 diversity_penalty. 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.
diversity_penalty is provided by the X Algorithm Toolkit MCP server (mrchartist/x-algorithm-toolkit). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
