List versions/milestones for a Redmine project.
AI agents call list_versions to retrieve information from Redmine MCP OAuth Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries data (versions/milestones) from a Redmine project without creating, modifying, deleting, or executing external operations. It is a straightforward read-only API endpoint. Severity is low because listing project metadata poses minimal risk even if invoked inappropriately.
From the tool's definition Tool name is 'list_versions' and description states it 'List versions/milestones for a Redmine project' — a retrieval operation with no side effects.
Attacks that exploit this kind of access
List versions/milestones for a Redmine project. It is categorised as a Read tool in the Redmine MCP OAuth Server MCP Server, which means it retrieves data without modifying state.
Register the Redmine MCP OAuth Server MCP server in PolicyLayer and add a rule for list_versions: 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 Redmine MCP OAuth Server. Nothing to install.
list_versions 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_versions 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_versions. 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_versions is provided by the Redmine MCP OAuth Server MCP server (zh/redmine_mcp_py). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
