Automate settlement chains in LangChain

Feed `get_balance` results directly into your decision logic to trigger `create_payment` calls. You define the thresholds where the agent executes transfers without manual intervention. This MCP Server provides the raw data your agents need to build reliable financial loops. Every tool output maps to your pipeline logic for consistent execution.

Trace every financial tool call

Monitor the latency and performance of `list_settlements` within your LangSmith traces. You get full visibility into how your agent processes payment data in real-time. Debugging becomes straightforward when you see exactly what the agent sent to the API. It removes the guesswork from complex payment workflows.
