LangChain Notion Tools

LangChain Notion Tools brings first-class read and write capabilities for Notion into LangChain agents and workflows. The package provides:

• NotionSearchTool – locate databases and pages with normalized results ready for LLMs.
• NotionWriteTool – create or update pages with rich block payloads, property updates, and dry-run previews.
• NotionToolkit – convenience factory bundling both tools with shared retry-aware clients.
• Block helper utilities, Markdown-to-Notion conversion, and a lightweight CLI for rapid debugging.

Why this package

• Agent native – tools implement the LangChain tool protocol with sync and async runtimes.
• Secure by design – block allowlists, size limits, and safe token redaction are enabled by default.
• LLM-friendly shape – inputs and outputs are powered by Pydantic models with JSON schema tuned for structured prompting.
• Ergonomic – ship a CLI, docs, and runnable examples so you can iterate quickly.

💡 Compatibility: Requires Python 3.9+, langchain-core>=0.3, and the official notion-client SDK.
