🔗 Map all workflow dependencies: internal workflows, external services, credentials. Identifies single points of failure.
AI agents call map_dependencies to retrieve information from n8n Workflow Builder without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs dependency analysis and mapping—a read-only operation that queries and reports on the structure and relationships within workflows and their external integrations. It retrieves information about dependencies and failure points but does not execute, modify, delete, or move any data. The risk is minimal (low severity) as misuse would only yield informational output about system architecture.
From the tool's definition Tool 'maps' and 'identifies' dependencies without modifying workflows, credentials, or services. Description uses passive language indicating analysis/retrieval ('Map all workflow dependencies', 'Identifies single points of failure') with no mention of…
Attacks that exploit this kind of access
🔗 Map all workflow dependencies: internal workflows, external services, credentials. Identifies single points of failure. It is categorised as a Read tool in the n8n Workflow Builder MCP Server, which means it retrieves data without modifying state.
Register the n8n Workflow Builder MCP server in PolicyLayer and add a rule for map_dependencies: 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 Workflow Builder. Nothing to install.
map_dependencies 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 map_dependencies 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 map_dependencies. 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.
map_dependencies is provided by the n8n Workflow Builder MCP server (schimmilab/n8n-workflow-builder). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
