Trace And Run Data Retrieval With Filtering And Pagination

LangSmith MCP Server - TypeScript implementation

Unique: Exposes LangSmith's trace and run query APIs through MCP's resource and tool abstractions, allowing Claude to retrieve and filter observability data using natural language queries that are translated into structured API calls. Handles response transformation and pagination transparently.

vs others: Provides query access to LangSmith traces directly within Claude's context, whereas the LangSmith UI or direct API calls require context switching and manual query construction.
