Upload any binary file, from a few bytes to 5 GB, to Notion with the Notion API, from Node.js or from AI agents through an MCP server. It fills the gap left by the official SDK, which exposes the raw file-upload endpoints but doesn't split files, needs the whole file in memory, and leaves retries and error handling to you.

# notion-multipart-uploader
> Upload any binary file, from a few bytes to 5 GB, to Notion with the Notion API, from Node.js or from AI agents through an MCP server. It fills the gap left by the official SDK, which exposes the raw file-upload endpoints but doesn't split files, needs the whole file in memory, and leaves retries and error handling to you. It runs Notion's multi-part upload (create, send parts, complete), reads from disk or any stream without loading the whole file into memory, handles retries, rate limits, progress and cancellation, and returns a file_upload ID to attach to pages, blocks, database properties, covers and comments.
- Install: `npm install notion-multipart-uploader`. Node.js 20 or later, no dependencies, ESM and CommonJS, TypeScript types.
- `uploadFile(apiKey, filePath)` uploads a file from disk. `uploadStream(apiKey, stream, mimeType, filename, { size })` uploads a stream of known size. `uploadToNotion(apiKey, data, mimeType, filename)` uploads a Buffer, Blob or string.
- Notion's limits: 20 MiB per request, 5 GB per file on paid workspaces, 5 MiB per file on free workspaces. Uploads must be attached within one hour of being created.
- MCP server for Claude Desktop, Claude Code and Cursor: `npx -y notion-large-file-upload-mcp`, configured with `NOTION_KEY` and `NOTION_UPLOAD_ALLOWED_DIRS`. It reads files from disk by path, so they don't pass through the model's context.

Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
