AI agents call show_time_entry to retrieve information from Redmine 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 and displays information about an existing time entry record. It performs a query operation without modifying, executing, or deleting any data. The verb 'Get details of' clearly indicates a read-only action. Given the Redmine context, this would typically be a GET API call to retrieve time entry metadata.
From the tool's definition Tool name 'show_time_entry' and description 'Get details of a time record' indicate a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access show_time_entry gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Redmine MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for show_time_entry:
{
"version": "1",
"default": "deny",
"tools": {
"show_time_entry": {}
}
}show_time_entry is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get details of a time record. It is categorised as a Read tool in the Redmine MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Redmine MCP Server MCP server in PolicyLayer and add a rule for show_time_entry: 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 Server. Nothing to install.
show_time_entry 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 show_time_entry 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 show_time_entry. 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.
show_time_entry is provided by the Redmine MCP Server MCP server (yonaka15/mcp-server-redmine). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
