Get authenticated download URL for a build artifact.
AI agents call get_artifact to retrieve information from Codemagic MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves a download URL for an existing artifact, which is a read-only operation. It does not create, modify, delete, or execute anything; it simply provides access to download a pre-existing artifact. The authentication mechanism ensures proper access control. The blast radius of misuse is limited to unauthorized access to artifacts that may already be accessible through other means in the CI/CD pipeline.
From the tool's definition The tool description explicitly states it "Get authenticated download URL for a build artifact" — a retrieval operation with no modification or destructive capability.
Documented attack patterns abuse exactly the kind of access get_artifact gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Codemagic MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_artifact:
{
"version": "1",
"default": "deny",
"tools": {
"get_artifact": {}
}
}get_artifact is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get authenticated download URL for a build artifact. It is categorised as a Read tool in the Codemagic MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Codemagic MCP Server MCP server in PolicyLayer and add a rule for get_artifact: 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 Codemagic MCP Server. Nothing to install.
get_artifact is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_artifact 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.
Set action: deny in the PolicyLayer policy for get_artifact. 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.
get_artifact is provided by the Codemagic MCP Server MCP server (stefanoamorelli/codemagic-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Codemagic MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
