# In-House Tools

In-House tools are prebuilt integrations maintained by OneByZero Neo. They cover common capabilities — web search, code execution, SMS — that most agents need without requiring custom API work. They are visible on the **In-House Tools** tab on the Integrations page.

## Available In-House Tools

**Search and Research** *(available in: flow)*

- **Google Serper API** — calls the Serper.dev Google Search API to give agents the ability to search the web for current information.
- **Exa Search** — search and content retrieval via the Exa API, optimised for AI applications.
- **Search API** — calls the searchapi.io API with configurable result limiting.
- **Serp Search API** — returns structured search engine results page data via the SERP API.
- **Tavily Search API** — a search engine built for LLMs and RAG, optimised for fast, accurate web search.
- **Tavily Extract API** — extracts raw content from a specified URL, enabling agents to read and process web pages.

**Code Execution** *(available in: flow)*

- **Calculator** — evaluates arithmetic expressions. Ensures mathematical accuracy without relying on LLM inference for calculations.
- **Python Code Structured** — a structured variant for converting dataclass code to executable tools.

**Communication** *(available in: voice)*

- **Twilio Send SMS** — sends SMS messages via the Twilio API.
- **Transfer to Human** — transfers the caller to a human support agent.

## Configuration Status

Each In-House tool card shows its current configuration state:

- **No configuration required** — the tool works immediately. Calculator falls into this category.
- **Configured** — the tool has been set up with credentials or parameters. For example, Twilio Send SMS requires API credentials before use.
- **Enabled / Disabled** — the toggle on each card controls whether the tool is available for agents to use.

Tools that require configuration show a setup form when you click the card. The form fields are specific to the tool — API keys, account identifiers, default parameters, and similar settings. Fill in the required fields and save to mark the tool as configured.

**Agent type compatibility**

Some In-House tools display an **Available in:** badge indicating which agent types support that tool (for example, voice-only tools show a `voice` badge). Confirm compatibility before selecting a tool for a specific agent type.

## Enabling a Tool for Agents

Once an In-House tool is configured and enabled:

1. Open the relevant agent in the builder.
2. For Agentic Flow agents, add the tool as a tool node in the flow canvas.
3. For Chatbot agents, add it as a block in the flow.

The tool becomes available to the agent using the credentials and settings configured in the Foundry. Individual agents do not store tool credentials — they reference the Foundry configuration.
