List all repositories currently in the MCP server
AI agents call list_repos to retrieve information from Code Expert 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 metadata about repositories without side effects. It is a straightforward read operation similar to 'list' operations. The severity is low because listing repositories exposes non-sensitive structural information about the server's configuration, with minimal blast radius even if misused by an AI agent.
From the tool's definition The tool 'list_repos' with description 'List all repositories currently in the MCP server' performs a retrieval operation that queries and enumerates existing repositories without modifying, deleting, or executing any operations.
Attacks that exploit this kind of access
List all repositories currently in the MCP server. It is categorised as a Read tool in the Code Expert MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Code Expert MCP Server MCP server in PolicyLayer and add a rule for list_repos: 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 Code Expert MCP Server. Nothing to install.
list_repos 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 list_repos 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 list_repos. 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.
list_repos is provided by the Code Expert MCP Server MCP server (lfnovo/code-expert-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
