What push_artifact does on NowAIKit — ServiceNow AI Toolkit
AI agents use push_artifact to create or update resources in NowAIKit — ServiceNow AI Toolkit, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your NowAIKit — ServiceNow AI Toolkit environment.
Why push_artifact is rated Medium
An AI agent can call push_artifact faster than any human can review: one bad instruction and it creates or modifies resources in NowAIKit — ServiceNow AI Toolkit by the hundred, each call as confident as the last.
Attacks that exploit this kind of access
The rule that runs push_artifact safely
PolicyLayer is an MCP gateway: it sits between your AI agents and NowAIKit — ServiceNow AI Toolkit, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For push_artifact, this is the rule to start with:
push_artifact stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect NowAIKit — ServiceNow AI Toolkit, apply this rule, and every push_artifact call is checked against it from then on.
Questions about push_artifact
Local sync: write edited fields back to an artifact (requires WRITE_ENABLED=true). Pass fields inline as {field:value}; if omitted and NOWAIKIT_SYNC_DIR is set, reads them from the pulled files on disk. Overwrites the listed fields with NO merge — run sync_status first, and pass expected_updated_on to abort if the instance changed since you pulled. It is categorised as a Write tool in the NowAIKit — ServiceNow AI Toolkit MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the NowAIKit — ServiceNow AI Toolkit MCP server in PolicyLayer and add a rule for push_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 NowAIKit — ServiceNow AI Toolkit. Nothing to install.
push_artifact is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the push_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 push_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.
push_artifact is provided by the NowAIKit — ServiceNow AI Toolkit MCP server (nowaikit). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
