WHAT IT DOES

What start_timer does on Huly

AI agents use start_timer to create or update resources in Huly, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Huly environment.

RISK

Why start_timer is rated Medium

Starting a timer creates or modifies a time-tracking record on an issue. It is a reversible write operation (a timestamp is recorded) with minimal blast radius — misuse would at worst create an erroneous time entry that can be corrected.

From the tool's definition Start a client-side timer on a Huly issue. Validates the issue exists and returns a start timestamp.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs start_timer safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Huly, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For start_timer, this is the rule to start with:

start_timer Rate-limited

start_timer 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.

FAQ

Questions about start_timer

What does the start_timer tool do? +

Start a client-side timer on a Huly issue. Validates the issue exists and returns a start timestamp. Use log_time to record the elapsed time when done. It is categorised as a Write tool in the Huly MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on start_timer? +

Register the Huly MCP server in PolicyLayer and add a rule for start_timer: 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 Huly. Nothing to install.

What risk level is start_timer? +

start_timer is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit start_timer? +

Yes. Add a rate_limit block to the start_timer 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.

How do I block start_timer completely? +

Set action: deny in the PolicyLayer policy for start_timer. 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.

What MCP server provides start_timer? +

start_timer is provided by the Huly MCP server (dugynoo/huly-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
