获取Java项目的统计信息，包括类数量、方法数量、调用关系数量等。
AI agents call get_project_statistics to retrieve information from JavaSinkTracer MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries project metadata statistics without modifying any data or executing code. It is purely informational and read-only in nature. The low severity reflects minimal blast radius if misused by an AI agent—worst case would be information disclosure about project structure, which is non-sensitive metadata.
From the tool's definition Tool description states it 'gets' (获取) Java project statistics including class count, method count, call relationship count, etc. No modification, deletion, or execution capabilities mentioned.
Attacks that exploit this kind of access
获取Java项目的统计信息，包括类数量、方法数量、调用关系数量等。. It is categorised as a Read tool in the JavaSinkTracer MCP MCP Server, which means it retrieves data without modifying state.
Register the JavaSinkTracer MCP server in PolicyLayer and add a rule for get_project_statistics: 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 JavaSinkTracer MCP. Nothing to install.
get_project_statistics 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 get_project_statistics 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 get_project_statistics. 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.
get_project_statistics is provided by the JavaSinkTracer MCP server (zacarx/javasinktracer_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
