What is better-notion-mcp CLAUDE.md?

A TypeScript MCP server that connects coding agents to the Notion API. Notion is a workspace for pages, databases, documents, comments, and files.

Use it to work with Notion pages, databases, blocks, users, workspaces, comments, converted content, file uploads, configuration, and help information.

It provides grouped tools for common Notion tasks and supports both local token-based use and remote HTTP access with per-user credentials.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.02316	$0.02316
Opus 5	$0.01158	$0.01158
Sonnet 5	$0.00463	$0.00463
Haiku 4.5	$0.00232	$0.00232

Security

Grade A, and why

better-notion-mcp CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
