Get a list of all available time tracking activities
AI agents call get_time_entry_activities 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 metadata about time tracking activities without side effects. It is purely informational and does not create, modify, delete, or execute any operations. This is a straightforward Read category tool with low severity since reading activity definitions poses minimal risk.
From the tool's definition Tool description states 'Get a list of all available time tracking activities' — a retrieval operation with no modification, deletion, or execution of external operations.

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 get_time_entry_activities:
{
"version": "1",
"default": "deny",
"tools": {
"get_time_entry_activities": {}
}
}get_time_entry_activities is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get a list of all available time tracking activities. 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 get_time_entry_activities: 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.
get_time_entry_activities 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 get_time_entry_activities 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 get_time_entry_activities. 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.
get_time_entry_activities is provided by the Redmine MCP Server MCP server (snowild/redmine-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Redmine MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
