Search workflows by name or tags
AI agents call search_workflows 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 or queries workflow metadata (name, tags) without any side effects. It does not create, modify, delete, execute, or move money. It is a straightforward read operation, making it low risk even if misused by an AI agent, as it only returns filtered lists of existing workflows.
From the tool's definition Tool description states 'Search workflows by name or tags' — a query operation with no modification or execution of workflows.
Attacks that exploit this kind of access
Search workflows by name or tags. 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 search_workflows: 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.
search_workflows 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 search_workflows 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 search_workflows. 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.
search_workflows is provided by the n8n MCP Server MCP server (nikolausm/n8n-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
