Question 1

What is ToolsConnector?

Accepted Answer

ToolsConnector is an open-source Python library that connects AI agents and Python apps to 53+ APIs — Gmail, Slack, GitHub, Stripe, OpenAI, Anthropic, and more — through a single standardized interface. It generates tool schemas for OpenAI, Anthropic, and Gemini and can serve any connector as a one-line MCP server.

Question 2

How do I install ToolsConnector?

Accepted Answer

Install via pip: pip install toolsconnector. For specific connectors use extras: pip install "toolsconnector[gmail,slack,github]". Requires Python 3.9+. Core dependencies are only pydantic, httpx, and docstring-parser.

Question 3

Does ToolsConnector work with OpenAI function calling?

Accepted Answer

Yes. Call kit.to_openai_tools() to generate OpenAI-compatible JSON Schema tool definitions for any combination of connectors. The same ToolKit supports Anthropic tool use via kit.to_anthropic_tools() and Google Gemini via kit.to_gemini_tools().

Question 4

What is MCP and does ToolsConnector support it?

Accepted Answer

MCP (Model Context Protocol) is an open standard for connecting AI models to external tools and data. ToolsConnector supports MCP out of the box: call kit.serve_mcp() to expose any connector as an MCP server for Claude Desktop, Cursor, Windsurf, or any compatible client. No extra configuration needed.

Yes. ToolsConnector is released under the Apache 2.0 license — free to use, modify, and distribute in commercial projects. No hosted backend required. Bring your own API keys (BYOK).
