WHAT IT DOES

What get_changeset does on ServiceNow-MCP

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

RISK

Why get_changeset is rated Low

The tool retrieves details of an update set, which is a read-only operation with no stated capacity to modify, delete, or execute code. However, update sets in ServiceNow can contain sensitive scripting and configuration information, elevating severity from low to medium.

From the tool's definition Tool name 'get_changeset' combined with description 'Get details of an update set' indicates retrieval of information without modification. The requirement for SCRIPTING_ENABLED=true suggests this may access sensitive configuration data.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs get_changeset safely

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

get_changeset Allowed

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_changeset": {}
  }
}

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

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