List builds (your own, or all if admin).
AI agents call list_builds to retrieve information from Overlord 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 existing build information without creating, modifying, deleting, or executing anything. It has minimal blast radius—an agent misusing it could only over-read data it may or may not have authorization to see, but cannot harm systems or data. The admin scope flag suggests access control, but the operation itself remains read-only.
From the tool's definition Tool name 'list_builds' and description 'List builds (your own, or all if admin)' indicate a query/retrieval operation with no mutation or side effects. The verb 'list' is a classic Read operation.

Attacks that exploit this kind of access
List builds (your own, or all if admin). It is categorised as a Read tool in the Overlord MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Overlord MCP Server MCP server in PolicyLayer and add a rule for list_builds: 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 Overlord MCP Server. Nothing to install.
list_builds 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_builds 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_builds. 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_builds is provided by the Overlord MCP Server MCP server (skeeminator/overlord-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
