notebooklm-mcp

Automate Google NotebookLM at scale. 33-endpoint HTTP REST API for n8n / Zapier / Make / curl, plus an MCP server for Claude Code / Cursor / Codex. Citation-backed Q&A, full Studio generation (audio · video · infographic · report · presentation · data table), multi-account rotation with auto-reauth across personal and Google Workspace accounts.

v3.2.0 — generated content can finally be deleted (content_delete): the endpoint had been declared and called by nothing since v3, so notebooks accumulated every draft ever asked for. Builds on 3.1.x, where generated content stopped coming back in the wrong language — the interface locale was overriding the language argument on both transports, silently, while reporting success. Also: reading a source's full indexed text (source_read, paginated), working source labels, and RPC refusals reported as refusals instead of as a rotated endpoint id. Built on a dual transport — the internal batchexecute RPC API (10-100× faster than scraping, immune to UI rebrands) with the Playwright browser as an automatic fallback, both shipped permanently. Batch-tested on overnight runs of 1 000+ questions. See the [changelog](./CHANGEL
