get_dependency_tree
AI agents call get_dependency_tree to retrieve information from ServiceNow CMDB MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves or queries dependency tree information from the ServiceNow CMDB. There is no evidence of creating, modifying, deleting, or executing operations. It is a read-only query operation with minimal blast radius if misused by an AI agent—worst case would be retrieving sensitive infrastructure relationships, but no irreversible changes or financial impacts are possible.
From the tool's definition Tool name 'get_dependency_tree' and sibling context ('dependency analysis', 'querying' CMDB) indicate data retrieval. No description provided, but the name strongly suggests fetching hierarchical dependency data without modification.
Attacks that exploit this kind of access
get_dependency_tree. It is categorised as a Read tool in the ServiceNow CMDB MCP Server MCP Server, which means it retrieves data without modifying state.
Register the ServiceNow CMDB MCP Server MCP server in PolicyLayer and add a rule for get_dependency_tree: 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 ServiceNow CMDB MCP Server. Nothing to install.
get_dependency_tree 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_dependency_tree 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_dependency_tree. 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_dependency_tree is provided by the ServiceNow CMDB MCP Server MCP server (ketiil/mcp-cmdb). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
