Get a specific workflow by ID
AI agents call n8n_get_workflow to retrieve information from n8n 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 workflow information by ID. It performs a query operation with no side effects, no data modification, and no irreversible actions. The retrieval of workflow metadata or configuration is a read-only operation. Severity is low because the blast radius of accidental misuse is minimal — retrieving an existing workflow cannot cause damage or unintended state changes.
From the tool's definition Tool name is 'n8n_get_workflow' and description states 'Get a specific workflow by ID' — the verb 'get' indicates retrieval without modification.
Attacks that exploit this kind of access
Get a specific workflow by ID. It is categorised as a Read tool in the n8n MCP Server MCP Server, which means it retrieves data without modifying state.
Register the n8n MCP Server MCP server in PolicyLayer and add a rule for n8n_get_workflow: 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 MCP Server. Nothing to install.
n8n_get_workflow 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 n8n_get_workflow 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 n8n_get_workflow. 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.
n8n_get_workflow is provided by the n8n MCP Server MCP server (shravan1610/n8n-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
