LangSmith Model Context Protocol (MCP) Server

The `langsmith-mcp-server` package provides a TypeScript implementation of the Model Context Protocol (MCP) server, designed to integrate with LangSmith, a platform for developing, evaluating, and monitoring large language model (LLM) applications. This server acts as a gateway, exposing LangSmith's rich data (including conversation history, prompts, traces, runs, datasets, and experiments) through a standardized protocol. It offers functional parity with its official Python counterpart and is currently at version 0.1.7, indicating active development with potential for non-stable API changes before a 1.0 release. The package is primarily intended to be run as a standalone service, leveraging environment variables for configuration, though it also provides programmatic interfaces for embedding or advanced customization. Its key differentiators include native TypeScript support, a comprehensive set of tools for accessing LangSmith data, and standardized char-based pagination for large data fetches.
