AI agents call list_views to retrieve information from Ignition without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation that enumerates existing Perspective views in an Ignition project. It has no side effects, does not execute code or commands, does not modify data, and does not delete anything. The blast radius of misuse is minimal—an agent could discover what views exist but cannot perform unauthorized actions through this tool alone.
From the tool's definition Tool name 'list_views' and description 'List all Perspective view paths in an Ignition project' indicate a retrieval operation that queries available view paths without modifying, executing, or deleting anything.
Attacks that exploit this kind of access
List all Perspective view paths in an Ignition project. It is categorised as a Read tool in the Ignition MCP Server, which means it retrieves data without modifying state.
Register the Ignition MCP server in PolicyLayer and add a rule for list_views: 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 Ignition. Nothing to install.
list_views 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 list_views 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 list_views. 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.
list_views is provided by the Ignition MCP server (nodeblue-ai/ignition-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
