Overview
From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.
[](https://github.com/Go-555/note-post-mcp)
The Universal MCP Server exposes tools for automated posting and draft saving to note.com. It reads Markdown files containing titles, body text, and tags, then publishes them to your note.com account using Playwright automation.
Installation
Prerequisites
- Node.js 18+
- A note.com account
note-state.jsonauthentication state file (obtained vianpm run login)- Set
NOTE_POST_MCP_STATE_PATHin your environment (optional, defaults to~/.note-state.json)
Install from GitHub
git clone https://github.com/Go-555/note-post-mcp.git cd note-post-mcp npm install npm run build
Install Playwright Browser
npm run install-browser
This installs the Chromium browser required for automation.
Get an authentication state file
Run the login script to authenticate with note.com:
npm run login
A browser window will open. Log in to note.com, then press Enter in the terminal. This creates a ~/.note-state.json file containing your authentication state. Store this file securely and reference it via NOTE_POST_MCP_STATE_PATH or pass it as a parameter.
Or install from npm (if published)
npm install -g note-post-mcp

To remove:
claude mcp remove Note Post MCP

Questions
What tools does Note Post expose?
2 in total: 0 read-only, 2 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.
Is Note Post safe to connect to an agent?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.
What credentials does Note Post need?
No credential environment variables were found in its source, so it appears to need none.
How does Note Post run?
It speaks stdio, so it runs as a local process your client starts. It is published on npm as @gonuts555/note-post-mcp at 1.0.7.
How current is this page?
The grade is for one exact copy of the source (754d8f42f0f4), read on 2026-10-08. The repository is watched and re-audited when it changes.
