WHAT IT DOES

What run does on Search

AI agents invoke run to trigger actions in Search. 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 run is rated High

The tool executes scripts or files, which can trigger arbitrary side effects depending on the script content and arguments provided. This falls under Execute rather than Write because it triggers external operations whose effects are not confined to data creation/modification. Severity is high because script execution has broad blast radius—an AI agent could inadvertently run malicious or unintended scripts.

From the tool's definition Tool name 'run' combined with description 'Runs a script or file with' indicates execution of arbitrary code/scripts.

RECOMMENDED RULE

The rule that runs run safely

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

run Rate-limited

run 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.

          "window": "minute",
          "max": 10,

        }
      ]
    }
  }
}

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

FAQ

Questions about run

What does the run tool do? +

Runs a script or file with. It is categorised as a Execute tool in the Search MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on run? +

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

What risk level is run? +

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

Can I rate-limit run? +

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

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

run is provided by the Search MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
