The @langchain/openai package provides built-in tools for the OpenAI Responses API via the tools export, plus the legacy DallEAPIWrapper class and a customTool helper.
import { ChatOpenAI, tools, DallEAPIWrapper, customTool } from "@langchain/openai";Server tools are hosted by OpenAI — no execute callback needed.
| Tool | Function | Description |
|---|---|---|
| Web Search | tools.webSearch() |
Search the web for up-to-date information. Supports domain filtering, user location, and configurable context size. |
| MCP | tools.mcp() |
Connect to remote MCP servers or OpenAI service connectors (Dropbox, Gmail, Google Calendar, Google Drive, Microsoft Teams, Outlook, SharePoint). |
| Code Interpreter | tools.codeInterpreter() |
Write and run Python code in a sandboxed container. Useful for data analysis, file generation, and visualization. |
| File Search | tools.fileSearch() |
Semantic and keyword search across uploaded files in vector stores. Supports metadata filtering and ranking. |
| Image Generation | tools.imageGeneration() |
