AI agents call list_repos to retrieve information from Astllm without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays metadata about previously indexed repositories (file count, symbol count, last indexed time). It is a pure read operation with no side effects—it does not create, modify, delete, or execute any code. The blast radius is minimal as misuse would only expose information about repository structure already indexed by the server.
From the tool's definition Tool name 'list_repos' and description 'List all indexed repositories with metadata' indicate a retrieval operation that queries existing indexed data without modification, deletion, or execution of external operations.
Attacks that exploit this kind of access
List all indexed repositories with metadata (file count, symbol count, last indexed time). It is categorised as a Read tool in the Astllm MCP Server, which means it retrieves data without modifying state.
Register the Astllm 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 Astllm. 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 Astllm MCP server (tluyben/astllm-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
