WHAT IT DOES

What job_wait does on Mcp Hands

AI agents invoke job_wait to trigger actions in Mcp Hands. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why job_wait is rated High

job_wait triggers real processes with real consequences. An agent gone sideways doesn't fire it once. It starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs job_wait safely

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

job_wait Rate-limited

job_wait stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

The button opens the PolicyLayer dashboard: create your workspace, connect Mcp Hands, apply this rule, and every job_wait call is checked against it from then on.

FAQ

Questions about job_wait

What does the job_wait tool do? +

Wait up to N seconds for a job to finish, then report it (short jobs only). It is categorised as a Execute tool in the Mcp Hands MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on job_wait? +

Register the Mcp Hands MCP server in PolicyLayer and add a rule for job_wait: 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 Mcp Hands. Nothing to install.

What risk level is job_wait? +

job_wait is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit job_wait? +

Yes. Add a rate_limit block to the job_wait 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 job_wait completely? +

Set action: deny in the PolicyLayer policy for job_wait. 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 job_wait? +

job_wait is provided by the Mcp Hands MCP server (huocai250/mcp-hands). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
