OpenAPITools SDK

Introduction

OpenAPITools JS 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

Install from npm

npm install @reacter/openapitools

Tool Execution Details

Python Tools

• Python tools are executed spawning new threads in nodejs
• Considerations:
  • Has interpreter startup overhead in JS environments
  • Full privacy (code runs locally)
  • Better for complex tasks requiring Python packages
• 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
• Very fast execution in nodejs environments
• Preferred for JavaScript/nodejs 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)

const toolsAdapter = new AnthropicAdapter(
    path.join(__dirname, "openapitools"),
    { verbose: true }
  );

API Mode (rate limits apply)

adapter = ToolsAdapter(api_key="your_api_key")

Performance Considerations

• Python Tools: Better for readability and when complex Python packages are needed
• Bash Tools: Significantly faster in nodejs environments with minimal overhead
• For maximum performance in JavaScript/nodejs environments, prefer Bash tools
• If you need more readability or complex packages, go with Python 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.
