# 🛠️Tools #### 1)BraveSearch API Wrapper around BraveSearch API - a real-time API to access Brave search results.

#### 2)Calculator Perform calculations on response.

#### 3)Chain Tool Use a chain as allowed tool for agent.

**4)Custom Tools** Function usually takes in structured input data. Let's say you want the LLM to be able to call Airtable Create Record [API](https://airtable.com/developers/web/api/create-records), the body parameters has to be structured in a specific way.

#### 5)Google Custom Search Wrapper around Google Custom Search API - a real-time API to access Google search results.

#### 6)OpenAPI Toolkit Load OpenAPI specification.

#### 7)Read File Read file from disk.

#### 8)Retriever Tool Use a retriever as allowed tool for agent.

#### 9)SearchApi Real-time API for accessing Google Search data.

#### 10)Serp API Wrapper around SerpAPI - a real-time API to access Google search results.

#### 11)Serper Wrapper around Serper.dev - Google Search API.

#### 12)Web Browser Gives agent the ability to visit a website and extract information.

#### 13)Write File Write file to disk.

**14)Code Interpreter by E2B** The Code Interpreter by E2B node integrates an open-source runtime for executing AI-generated code in secure cloud sandboxes. For instance, when a user requests a bar graph of data, the LLM generates the necessary Python code, which is then executed by E2B. The output, including images, code, and text, is returned to the LLM for final processing before display.

**15)Chatflow Tool** Execute another chatflow and get the response.

**16)Request Get** Execute HTTP GET requests.

**17)Request Post** Execute HTTP POST requests.

**18)Chain Tool** The **Chain Tool** node allows you to incorporate existing chains as tools within your agent workflows. This enables modular design by reusing predefined sequences of operations.

**19)Composio** The **Composio** node facilitates integration with over 200 applications, enhancing the capabilities of your AI agents by allowing them to interact with various external tools and services.

**20)Exa Search** The **Exa Search** node serves as a wrapper around the Exa Search API, a search engine fully designed for use by LLMs. This integration enables your agents to perform searches and retrieve relevant information efficiently.

**21)SearXNG** The **SearXNG** node integrates the SearXNG metasearch engine, allowing your agents to perform searches across multiple sources. To use this node, drag and drop it onto the canvas, fill in the Base URL (e.g., ), and specify other search parameters as needed.

**22)Tavily API** The **Tavily API** node is a wrapper around the TavilyAI API, providing real-time, accurate search results tailored for LLMs and Retrieval-Augmented Generation (RAG) applications. To set it up, add the Tavily API node from the LangChain > Tools section and create credentials for Tavily.

**23)** **Wolfram Alpha** The **Wolfram Alpha** node connects your agents to Wolfram Alpha's computational intelligence engine, enabling them to perform complex calculations and access a vast repository of knowledge.
