Get node details
AI agents call get_node to retrieve information from Pulse Workflow 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 or queries data about workflow nodes with no side effects. It is a read-only operation consistent with the Read category. Low severity because retrieving node details has minimal blast radius even if misused by an AI agent.
From the tool's definition Tool name 'get_node' with description 'Get node details' indicates a retrieval operation that queries existing node information without modification.
Attacks that exploit this kind of access
Get node details. It is categorised as a Read tool in the Pulse Workflow MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Pulse Workflow MCP Server MCP server in PolicyLayer and add a rule for get_node: 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 Pulse Workflow MCP Server. Nothing to install.
get_node 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_node 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_node. 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_node is provided by the Pulse Workflow MCP Server MCP server (pulse-intelligence/pulse-workflow-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
