AI agents use update_time_entry to create or update resources in Redmine MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Redmine MCP Server environment.
This tool modifies time entries, which are reversible changes to data records. It does not delete data (not Destructive), execute arbitrary code (not Execute), or move money (not Financial). Update operations are classified as Write. Severity is medium because misuse could corrupt time tracking data, affecting project accounting and employee records, but changes are reversible.
From the tool's definition Tool name 'update_time_entry' and description 'Update an existing time record' indicate modification of data (a time entry record).
Documented attack patterns abuse exactly the kind of access update_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 update_time_entry:
{
"version": "1",
"default": "deny",
"tools": {
"update_time_entry": {
"limits": [
{
"counter": "update_time_entry_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}update_time_entry stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Update an existing time record. It is categorised as a Write tool in the Redmine MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Redmine MCP Server MCP server in PolicyLayer and add a rule for update_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.
update_time_entry is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the update_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 update_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.
update_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.
