Provides a comprehensive explanation of a repository
AI agents call explain_codebase to retrieve information from RepoMemory without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs static analysis and information retrieval on repository structure and code content. It does not create, modify, delete, or execute any operations. The output is explanatory/informational only.
From the tool's definition The tool 'explain_codebase' is described as providing 'a comprehensive explanation of a repository' — it retrieves and analyzes information about code without modifying it.
Attacks that exploit this kind of access
Provides a comprehensive explanation of a repository. It is categorised as a Read tool in the RepoMemory MCP Server, which means it retrieves data without modifying state.
Register the RepoMemory MCP server in PolicyLayer and add a rule for explain_codebase: 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 RepoMemory. Nothing to install.
explain_codebase 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 explain_codebase 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 explain_codebase. 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.
explain_codebase is provided by the RepoMemory MCP server (praveenjayaprakash-jp/repomemory). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
