Returns a structured explanation of the repository
AI agents call explain_repo 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 retrieves and presents information about a repository structure and context without modifying, deleting, or executing any code. It is a read-only analysis operation consistent with tools like 'explain_codebase' on the same server. The low severity reflects that misuse would only expose information, not cause operational damage.
From the tool's definition Tool name 'explain_repo' and description 'Returns a structured explanation of the repository' indicates a query/retrieval operation with no side effects.
Attacks that exploit this kind of access
Returns a structured explanation of the 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_repo: 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_repo 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_repo 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_repo. 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_repo 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.
