mcp-use

Trace mcp-use agent runs in Muster — full visibility into MCP tool invocations.

mcp-use is an MCP (Model Context Protocol) client that lets AI agents securely connect to external data sources and tools. Muster (langfuse) tracing is built in — set credentials and every conversation, tool call, and context update is captured.
