分析指定请求参数的加密方式，通过密文格式和长度推断可能的算法
AI agents call crypto_analyze_param to retrieve information from Js Reverse without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs analysis/inference by examining ciphertext format and length to identify encryption algorithms. It reads/inspects data without executing code, modifying data, or performing destructive operations. It is a passive analysis/read operation. Severity is low as it only reads and analyzes existing data.

Attacks that exploit this kind of access
分析指定请求参数的加密方式，通过密文格式和长度推断可能的算法. It is categorised as a Read tool in the Js Reverse MCP Server, which means it retrieves data without modifying state.
Register the Js Reverse MCP server in PolicyLayer and add a rule for crypto_analyze_param: 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 Js Reverse. Nothing to install.
crypto_analyze_param 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 crypto_analyze_param 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 crypto_analyze_param. 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.
crypto_analyze_param is provided by the Js Reverse MCP server (jenn619/js-reverse-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
