WHAT IT DOES

What pull does on Test

AI agents invoke pull to trigger actions in Test. 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 pull is rated High

Pulling a Docker image is not a pure read — it executes a network operation, modifies local Docker image storage, and interacts with an external registry. It cannot be classified as Read because it has real side effects (disk writes, network calls, potential credential usage). It is not Destructive or Financial, so Execute is the most appropriate category.

From the tool's definition 'Pulls a Docker image from a registry' — this triggers an external network operation (downloading from a remote registry) with side effects on the local Docker environment

RECOMMENDED RULE

The rule that runs pull safely

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

pull Rate-limited

pull 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.

          "max": 10,

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

FAQ

Questions about pull

What does the pull tool do? +

Pulls a Docker image from a registry and returns structured result with digest info. It is categorised as a Execute tool in the Test MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on pull? +

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

What risk level is pull? +

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

Can I rate-limit pull? +

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

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

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