Get a workflow by ID (returns full workflow JSON)
AI agents call workflow_get to retrieve information from N8n Fabric without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and returns workflow data without modifying, deleting, or executing anything. It is a read operation. Severity is medium rather than low because workflows may contain sensitive information (credentials, API keys, business logic) that could be exposed if an agent retrieves workflows without authorization, posing a moderate risk depending on what data the workflow contains and who can access it.
From the tool's definition Tool name 'workflow_get' and description 'Get a workflow by ID (returns full workflow JSON)' indicate data retrieval with no side effects.
Attacks that exploit this kind of access
Get a workflow by ID (returns full workflow JSON). It is categorised as a Read tool in the N8n Fabric MCP Server, which means it retrieves data without modifying state.
Register the N8n Fabric MCP server in PolicyLayer and add a rule for workflow_get: 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 N8n Fabric. Nothing to install.
workflow_get 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 workflow_get 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 workflow_get. 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.
workflow_get is provided by the N8n Fabric MCP server (ry-ops/n8n-fabric). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
