Retrieve the codebase of a Java project. It must be filtered by package and scope and must specify the format of the output.
AI agents call java_codebase_retrieve to retrieve information from Coder Toolbox MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries Java project source code with no side effects. It falls squarely into the Read category. The filtering and format options are data access controls, not operations that modify, delete, or execute code.
From the tool's definition Tool name and description indicate retrieval operation: 'Retrieve the codebase of a Java project.' No modification, deletion, or execution mentioned. Filtering by package/scope and output format specification are read-side parameters.
Attacks that exploit this kind of access
Retrieve the codebase of a Java project. It must be filtered by package and scope and must specify the format of the output. It is categorised as a Read tool in the Coder Toolbox MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Coder Toolbox MCP Server MCP server in PolicyLayer and add a rule for java_codebase_retrieve: 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 Coder Toolbox MCP Server. Nothing to install.
java_codebase_retrieve 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 java_codebase_retrieve 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 java_codebase_retrieve. 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.
java_codebase_retrieve is provided by the Coder Toolbox MCP Server MCP server (lamemind/coder-toolbox-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
