{"library":"langsmith-mcp-server","type":"library","category":null,"description":"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.","language":"javascript","status":"active","version":"0.1.7","tags":["javascript","typescript"],"last_verified":"Wed May 27","install":[{"cmd":"npm install langsmith-mcp-server","imports":["import { startServer } from 'langsmith-mcp-server'","import { LangSmithMcpServer } from 'langsmith-mcp-server'","import type { ServerOptions } from 'langsmith-mcp-server'"]},{"cmd":"yarn add langsmith-mcp-server","imports":[]},{"cmd":"pnpm add langsmith-mcp-server","imports":[]}],"homepage":"https://langsmith.com","github":null,"docs":null,"changelog":null,"pypi":null,"npm":"https://www.npmjs.com/package/langsmith-mcp-server","openapi_spec":null,"status_page":null,"smithery":null,"compatibility":{"summary":{"python_range":"18–22","success_rate":0,"avg_install_s":null,"avg_import_s":null,"wheel_type":null},"url":"https://checklist.day/v1/registry/langsmith-mcp-server/compatibility"}}
