WHAT IT DOES

What artifact.describe does on Visionmcp

AI agents call artifact.describe to retrieve information from Visionmcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why artifact.describe is rated Low

The verb 'describe' indicates data retrieval with no modification, creation, or deletion. This is a read-only operation that queries artifact metadata or content. Severity is low because the blast radius of misuse is limited to information disclosure of artifact descriptions, with no ability to modify systems or data.

From the tool's definition Tool description states 'Describe an input artifact' — a descriptive action that retrieves or queries information about an artifact without modifying it. The mention of authentication is a control mechanism, not a side effect.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs artifact.describe safely

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

artifact.describe Allowed

artifact.describe is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "artifact.describe": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

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

How do I enforce a policy on artifact.describe? +

Register the Vision MCP server in PolicyLayer and add a rule for artifact.describe: 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 Visionmcp. Nothing to install.

What risk level is artifact.describe? +

artifact.describe is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit artifact.describe? +

Yes. Add a rate_limit block to the artifact.describe 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 artifact.describe completely? +

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

artifact.describe is provided by the Vision MCP server (joshuahickscorp/visionmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
