AI agents call get_tags to retrieve information from Clockify MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns tag data from a workspace without creating, modifying, deleting, or executing any operations. It is a straightforward read operation on existing data with minimal blast radius if misused by an agent.
From the tool's definition Tool name 'get_tags' and description 'Get all tags in a workspace' indicate a retrieval operation with no data modification or side effects.
Documented attack patterns abuse exactly the kind of access get_tags gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Clockify MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_tags:
{
"version": "1",
"default": "deny",
"tools": {
"get_tags": {}
}
} get_tags is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Get all tags in a workspace. It is categorised as a Read tool in the Clockify MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Clockify MCP Server MCP server in PolicyLayer and add a rule for get_tags: 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 Clockify MCP Server. Nothing to install.
get_tags 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_tags 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_tags. 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_tags is provided by the Clockify MCP Server MCP server (ratheesh-aot/clockify-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Clockify 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.
