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

Tool 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_json dictionary and can access environment variables through input_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)


adapter = ToolsAdapter(folder_path="/path/to/tools")

API Mode (rate limits apply)


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.
