# LangGraph

The LangGraph use case addresses multi-step pipeline security. LangGraph makes it easy to build complex agent workflows, but each step in the graph may need different tool access, and blanket read permissions across the entire pipeline create unnecessary risk. Civic scopes access per step, so a research node can read email but a summarization node cannot send it. The page walks through connecting LangGraph to Civic, configuring per-tool guardrails, and using the audit log to trace which pipeline step made which tool call. Every node in your graph gets exactly the permissions it needs and nothing more.
