AI agents call list_milestones to retrieve information from Codecks 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 milestone information (milestone names and associated card counts) without creating, modifying, deleting, or executing any operations. It is a read-only query operation with no side effects, fitting the 'Read' category. Severity is low because viewing project milestones poses minimal risk even if exposed to an AI agent; the information is typically non-sensitive project metadata.
From the tool's definition Tool name 'list_milestones' and description 'List all milestones with card counts' indicate a query/retrieval operation with no modification or deletion of data.
Attacks that exploit this kind of access
List all milestones with card counts. It is categorised as a Read tool in the Codecks MCP Server, which means it retrieves data without modifying state.
Register the Codecks MCP server in PolicyLayer and add a rule for list_milestones: 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 Codecks. Nothing to install.
list_milestones 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_milestones 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_milestones. 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_milestones is provided by the Codecks MCP server (rangogamedev/codecks-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
