List all Redmine groups (requires admin).
AI agents call list_groups 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 displays existing group data from Redmine without modifying, creating, or destroying anything. Although it requires admin permissions, the action itself is read-only. The blast radius of misuse is minimal—an attacker gains visibility into group information but cannot alter system state or trigger side effects.
From the tool's definition Tool name 'list_groups' and description 'List all Redmine groups' indicate a query/retrieval operation with no data modification, creation, or deletion. The 'list' verb is characteristic of Read operations.

Attacks that exploit this kind of access
List all Redmine groups (requires admin). 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_groups: 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_groups 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_groups 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_groups. 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_groups 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.
list_groups is one line of Redmine MCP OAuth Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
