OpenAPITools SDK
Introduction
OpenAPITools Python package enables developers to manage, and execute tools across multiple AI API providers. It provides a unified interface for working with tools in Anthropic's Claude, OpenAI's GPT models, and LangChain frameworks.
With OpenAPITools, you can:
- Create tools as Python or Bash scripts with standardized input/output
- Access these tools through a single, consistent SDK
- Integrate tools with Claude, GPT, and LangChain models
- Build interactive chatbots that can use tools to solve complex tasks
Installation
Prerequisites
- Python 3.8 or later
- Access keys to at least one of the supported AI providers (Anthropic, OpenAI, or LangChain)
- Get an API key for OpenAPITools from the Settings page
Install from PyPI
bash
pip install reacter-openapitools requestsIf you're using the LangChain adapter, you’ll also need to install langchain and langchain-core:
bash
pip install langchain langchain-coreTool Execution Details
Python Tools
- Python tools are executed using Python's
exec()function directly in the current process - Benefits:
- No interpreter startup overhead
- Full privacy (code runs locally)
- Faster execution compared to subprocess methods
- Python tools receive arguments via an
input_jsondictionary and can access environment variables throughinput_json["openv"]
Bash Tools
- Bash tools are executed as subprocesses
- Arguments are passed as JSON to the script's standard input
- Recommended for non-Python environments for better performance
- Note: Bash tools should be tested in Linux environments or WSL, as they may not function correctly in Windows
Usage Modes
Local Mode (preferred)
python
adapter = ToolsAdapter(folder_path="/path/to/tools")API Mode (rate limits apply)
python
adapter = ToolsAdapter(api_key="your_api_key")Performance Considerations
- Python Tools: Best for Python environments, executed in-process with minimal overhead
- Bash Tools: Better for non-Python servers or when isolation is needed
- For maximum performance in non-Python environments, prefer Bash tools
Security and Privacy
- All tool execution happens locally within your environment
- No code is sent to external servers for execution
- Environment variables can be securely passed to tools
Integration with AI Models
OpenAPITools provides native integration with:
- Anthropic's Claude
- OpenAI's GPT models
- LangChain frameworks
This allows you to build AI assistants that can leverage tools to perform complex tasks.
