AI agents call codegen_build_context to retrieve information from DBJavaGenix without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool builds/assembles an in-memory template context for code generation but explicitly does not write to disk or render output. This is a pure data preparation/read operation with no side effects, making it a Read category tool with low severity.
From the tool's definition 构建代码生成所需的完整模板上下文(不写盘,不渲染) — explicitly states 'no disk write, no rendering'
Documented attack patterns abuse exactly the kind of access codegen_build_context gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and DBJavaGenix, and nothing reaches the server without passing your rules. This is the rule we recommend for codegen_build_context:
{
"version": "1",
"default": "deny",
"tools": {
"codegen_build_context": {}
}
}codegen_build_context is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

构建代码生成所需的完整模板上下文(不写盘,不渲染)。. It is categorised as a Read tool in the DBJavaGenix MCP Server, which means it retrieves data without modifying state.
Register the DBJavaGenix MCP server in PolicyLayer and add a rule for codegen_build_context: 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 DBJavaGenix. Nothing to install.
codegen_build_context 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 codegen_build_context 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 codegen_build_context. 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.
codegen_build_context is provided by the DBJavaGenix MCP server (zhaoxingpeng/dbjavagenix). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
