Rednote Gate MCP Server

rednote-gate

中文说明

rednote-gate drives ONE dedicated throwaway RedNote (Xiaohongshu) account. Never point it at a primary or brand account. It works by browser automation, which is against RedNote's terms of service. The account can be rate limited or banned. Only use an account you can afford to lose.

Website: https://yashshelar007.github.io/rednote-gate/

It is a local MCP server for Claude Code, Claude Desktop and Codex. Reads run directly. Every write waits in a queue until a human clicks Approve on a local web page.

Quick start

Install from npm

npm install -g rednote-gate
rednote-gate setup

That installs Chromium, opens the QR login for your throwaway account, and connects rednote-gate to Claude Code. Your data and login live in ~/.rednote-gate.

Or from a clone

git clone https://github.com/YashShelar007/rednote-gate.git
cd rednote-gate
npm run setup

Same steps, plus the build. A clone that already has a login in .session/ keeps its data in the clone folder.

Then use rednote-gate's prompts. Claude Code shows them as slash commands:

Or just ask in plain words ("post these two photos about my hike"). The first time you use a rednote tool, a small background service starts. It owns the browser, the approval page and the worker, and it keeps running after you close Claude Code, so the approval page always works and approved items always run. It closes the browser window after 5 idle minutes. Stop it with rednote-gate stop (npm run stop in a clone). When something is queued, the approval page opens in your browser and your Mac shows a notification. You click Approve. About 30 seconds later it runs, and the page shows a screenshot of the result. You get a notification when it is done, or if RedNote ever shows a captcha.

Status: every flow was checked against the live site on 2026-10-06 on a rednote.com account, headed: four reads, and one real publish, draft, comment and reply, each approved by a human on the approval page. See Last verified against the live site.

How it fits together

The model calls tools. You choose prompts. The background service, the approval page and the rednote-gate CLI are not part of MCP. The approval page is a local web page on 127.0.0.1. It sits outside MCP on purpose, so the model cannot approve its own writes.

What it does

rednote-gate is a local stdio MCP server. It needs Node 20 or newer. It is written in TypeScript and drives Playwright Chromium on your own machine.

Read tools run straight away:

Write tools only add an item to the queue and return its queue id. They never touch the browser.

For rednote_reply_comment, pass the id, author and text exactly as rednote_get_comments returned them. Before replying, the worker reads the comment with that id from the page and checks that its author and text still match exactly. If not, it does not reply.

Titles, comments and replies must be a single line: a line break would be typed as Enter, which can send a comment early. The body of a note may have line breaks.

Note URLs must look like https://www.xiaohongshu.com/explore/<id>?xsec_token=... (or www.rednote.com for overseas accounts). Take them from rednote_search results. Bare URLs without the token are refused, because RedNote answers them with a captcha. See docs/friction.md.

How the approval gate works

A short example:

1. You ask Claude: "Post a note about my desk setup with /Users/me/pics/desk.jpg."
2. Claude calls rednote_create_post. The server checks the image, copies it into the queue and hashes it. It returns a queue id such as q_20261006T153012_ab12. No browser opens. Nothing is posted.
3. You run rednote-gate approve and open the link it prints. The page shows the exact title, body and image. You click Approve.
4. The worker checks the queue every 10 seconds. It waits 30 seconds after your click, so you can still press Cancel, then picks up the item if the budget allows. It writes an attempt line to the ledger, then opens the creator page, uploads the image and types the text.
5. In dry run mode (the default) it stops before the final click. The item becomes dry_run. In live mode (rednote-gate live) it clicks publish. The item becomes posted.
6. Claude can call rednote_queue_status to see the result. It never gets the approval link.

Clicking Approve only marks the item. It does not post anything by itself. There is no approval in chat. Telling Claude "yes, post it" changes nothing.

Statuses

pending  -> approved | rejected
approved -> posting  | rejected    (Cancel)
posting  -> posted | dry_run | failed | unknown

Queuing an identical write returns the existing id instead of a second item. Identical means same tool, same arguments and same image bytes. This applies while the first one is pending, approved, posting, posted or unknown.

Guardrails

• Approval in code. Write tools only queue. The worker clicks the final button only in live mode, and only on an approved item.
• What you approve is what posts. Images are copied into the queue and hashed when queued. Only real JPEG, PNG or WebP files pass, checked by file signature. Each image can be at most 20 MB. A note takes 1 to 9 images. That is a project limit, not RedNote's.
• Daily budget. At most RN_DAILY_WRITES live attempts (default 5) in any rolling 24 hours. Comments and replies also need RN_COMMENT_GAP_MIN minutes (default 10) since the last live comment or reply attempt. The budget is worked out from the ledger, so a restart does not reset it. Failed and unknown live attempts count. Dry runs do not. An approved item over budget waits. The approval page shows when the next slot opens.
• Undo window. The worker waits 30 seconds after Approve. Until then, Cancel stops it.
• An approval is tied to its mode. "Approve dry run" only ever runs as a dry run. If you restart in live mode, earlier dry-run approvals do not run; the page tells you to cancel and approve again.
• Read back before sending. After typing, every field is read back. If a topic or mention picker, or anything else, changed the text, it stops before the final click.
• Crash safety. The attempt line is written before the browser starts, so a crash still uses up budget. A live item cut off mid attempt becomes unknown and is never retried. A dry run cut off mid attempt becomes failed.
• Checked again before sending. Image hashes are re-checked before upload. A reply only goes out if the target comment still exists and its text still matches what you approved.
• Halt on friction. If RedNote shows a captcha or a "too frequent" warning, rednote-gate writes a blocked line to the ledger. It stops the worker and refuses read tools. Write tools can still queue, since queuing never touches the browser. It does not retry. The halt survives a restart. A human clicks Resume on the approval page to continue.
• No bare note URLs. URLs without xsec_token are refused before the browser opens.
• One browser owner. Only the service drives the browser, guarded by a lock file in data/. Every MCP host (Claude Code, Claude Desktop, Codex, several sessions at once) talks to that one service, so there is never a second browser on the account.
• Dry run by default. It stays in dry run until you run rednote-gate live or go live on the Settings page. The mode saved in settings.json wins over RN_DRY_RUN.

Terms of service warning

This project drives the RedNote website with a real browser and a real logged-in session. RedNote's terms do not allow this. Using it can get the account rate limited, restricted or banned. That risk is yours.

Two Xiaohongshu notices from 2026 also apply (checked 2026-10-07). On 2026-03-10 it announced action against "AI 托管" (AI hosting) accounts (IT之家 report). An account that now and then lets AI hosting write, post or interact for it gets warnings and reduced distribution. An account that registers, posts or interacts directly through AI hosting tools is banned, and so is one whose public notes were all posted that way. On 2026-04-27 it published rules for AI content (IT之家 report). Creators should label notes that AI generated or polished when they publish them, and the platform adds its own label to AI content left unlabeled. Using AI to run an account against the rules is punished in steps, up to a ban.

An Approve click does not make an account compliant. A throwaway account that only posts through rednote-gate matches the ban description in the March notice.

• Use ONE dedicated throwaway account. Never a primary account. Never a brand account.
• Keep writes few and far apart. The budget is a ceiling, not a target.
• Respect the law where you live and the people whose notes you read or reply to.

Setup

You need Node 20 or newer, a RedNote account made for this purpose, and the phone that account is logged in on.

npm install -g rednote-gate
rednote-gate setup

rednote-gate setup installs Chromium with the package's own Playwright, then runs these two steps, which you can also run one by one:

rednote-gate login
rednote-gate connect

From a clone, npm run setup does the same after npm install and npm run build. In a clone, npm run login, connect, live, dry, stop and approve run the same commands.

rednote-gate connect adds rednote-gate to Claude Code for all your projects (claude mcp add --scope user). It also prints the config for Claude Desktop and Codex. See below.

It starts in dry run: approved items fill in the form but never publish. When a dry run looks right, switch modes with one command:

rednote-gate live

It says what live means and asks you to confirm. rednote-gate live --yes skips the question. The mode is saved to settings.json, the same file the dashboard's Settings page writes, and the service restarts on the next tool call. rednote-gate dry switches back. Approvals given in one mode never run in the other.

More commands:

With no command, rednote-gate runs the MCP server. That is what your MCP host starts.

Where your data lives

Data and login live in ~/.rednote-gate: data/ for the queue, ledger and settings, and .session/ for the login. RN_HOME moves both. A clone that already has .session/ from an older version keeps using its own folder.

rednote-gate login opens a visible browser at xiaohongshu.com. Overseas accounts get sent to rednote.com: the login follows, reloads on rednote.com and asks you to scan the new QR code. It records which site your account uses in .session/site. Scan the QR code with the throwaway account's phone. If the page shows you logged in but the terminal does not move on, press Enter there. It then visits creator.xiaohongshu.com to pick up the creator session; scan again if that site asks. It saves the session to .session/state.json with owner-only permissions (0600).

Quit your MCP host before running it: only one process may drive the browser.

That file is a credential. It is git-ignored. rednote-gate never prints it. Never share it, commit it or copy it to a shared disk.

Then add the server to your MCP host.

Wiring into Claude Code, Claude Desktop and Codex

rednote-gate connect prints all three for your install. With a global npm install the command is rednote-gate. From a clone, use node with the absolute path to dist/cli.js.

Claude Code:

claude mcp add rednote-gate --scope user -- rednote-gate

Claude Desktop (in claude_desktop_config.json):

{
  "mcpServers": {
    "rednote-gate": {
      "command": "rednote-gate",
      "args": []
    }
  }
}

Claude Desktop may not see your shell's PATH. If it cannot start the server, use absolute paths: command is the output of which node, and args is ["<npm root -g>/rednote-gate/dist/cli.js"].

Codex (in ~/.codex/config.toml):

[mcp_servers.rednote-gate]
command = "rednote-gate"
args = []

An env block is optional. See Environment variables.

Never load a browser MCP server, such as @playwright/mcp, in the same host session as rednote-gate. An agent with a browser could open the approval page and click Approve.

The approval page

The page runs at http://127.0.0.1:7317 while the MCP server runs. Change the port with RN_APPROVAL_PORT.

Get the link:

rednote-gate approve

It prints the URL with a secret token. The server makes a new token each time it starts, so get a fresh link after a restart. The link is also stored in data/approval-url with owner-only permissions.

The page shows:

• for posts and drafts: the exact title, body and images
• for comments: the comment text
• for replies: the comment being replied to, and the reply text
• live writes used in the last 24 hours, and when the next slot opens
• the mode: DRY RUN or LIVE
• a halt banner if a captcha or warning stopped the worker
• after each attempt, a screenshot of what the browser showed at the end
• it refreshes itself every 5 seconds while something is approved or running

It opens by itself when Claude queues a write (at most once a minute). rednote_open_approval_page opens it on request.

The page also shows today's usage as meters, and links to Settings: mode (dry run or live, with a confirmation tick to go live), writes per day, likes per day, minutes between comments, and notifications. Settings are saved to data/settings.json and apply to the next item that runs, without a restart. They cannot go past the hard maximums: 20 writes, 50 likes, 2 minutes between comments.

Buttons:

How the page is protected:

• It binds to 127.0.0.1 only.
• It checks the Host header, which blocks DNS rebinding.
• Every request needs the token.
• State changes are POST only and must come from the same origin. This blocks other websites.
• It cannot be framed. It sends a strict Content Security Policy and no referrer.

Queue file format

All data lives in ~/.rednote-gate/data/, or in data/ in a clone that already had a login. RN_HOME or RN_DATA_DIR moves it. The folder is owner-only. In a clone it is git-ignored.

A queue item:

{
  "id": "q_20261006T153012_ab12",
  "tool": "create_post",
  "args": { "title": "...", "body": "...", "images": ["q_20261006T153012_ab12/0.jpg"] },
  "imageSha256": ["..."],
  "contentHash": "...",
  "createdAt": "2026-10-06T15:30:12.000Z",
  "status": "pending",
  "history": [{ "status": "pending", "at": "2026-10-06T15:30:12.000Z" }]
}

Image paths in args.images are relative to data/queue/. imageSha256 holds one hash per image. contentHash covers the tool, the arguments and the image hashes, and is what duplicate checks compare. Each status change adds one entry to history.

Ledger format

data/ledger.jsonl holds one JSON object per line.

Not every field appears on every line. An attempt line is written before the browser starts. A result line follows when the attempt ends. If the process dies in between, there is an attempt with no result. On the next start the item becomes unknown (live) or failed (dry run), and a result line records that.

The budget counts attempt lines with dryRun: false from the last 24 hours. The halt also comes from the ledger: a blocked line with no later resumed line means halted, even after a restart.

If a line is not valid JSON, writes stop until you fix or remove that line. A budget that cannot be read fails closed.

Environment variables

Limits and the port must be whole numbers. A typo stops the server with an error instead of turning a limit off.

The dashboard's Settings page writes data/settings.json, which wins over these variables for limits, mode and notifications.

Set these in your MCP host's env block. The rednote-gate commands read them from your shell. If you set RN_HOME, RN_DATA_DIR or RN_SESSION_PATH, export the same values in your shell. rednote-gate connect copies those three into the Claude Code entry.

Dry run is not free of side effects. It opens the page, uploads images to RedNote's creator page and types the text. It only skips the final publish, save or send click.

What it does not do

• Post anything without a human click on Approve. There is no approval in chat.
• Use more than one account, more than one browser context, or run writes at the same time.
• Bulk post, or schedule posts nobody is watching.
• Solve captchas, or retry after a block.
• Favorite, follow or send messages. (Likes were added on 2026-10-06 at the owner's request, behind the same approval page and their own daily cap.)
• Run the account in a cloud browser.
• Touch a primary or brand account.

Known limits

• A browser agent could approve. An agent with its own browser tool on the same machine could open the approval page and click Approve. Never load a browser MCP server in the same host session. The same goes for any process running as your user: it can read data/approval-url. The gate stops the model acting through rednote-gate's tools. It cannot stop other software you run.
• The service keeps running. It starts on first use and stays up until rednote-gate stop or a reboot. After updating, run rednote-gate stop; the next tool call starts it fresh. Settings apply without a restart. Its log is data/service.log.
• Selectors drift. RedNote changes its pages. The selectors live in the SEL object in src/rednote.ts. Fix them there. Record the evidence in the capture block in PROTOTYPE-RUNSHEET.md and in docs/friction.md.
• Unknown blocks a re-queue. An unknown item blocks an identical write. If you check by hand and it did not post, change the text before queuing it again.
• Drafts stay in rednote-gate's browser. RedNote's web creator site keeps drafts in the browser, not in your account (its own notice says so). A draft saved by rednote-gate does not appear in your phone app. rednote-gate keeps it across restarts by saving the browser's IndexedDB with the session; to finish it, open the creator site's 草稿箱 in rednote-gate's browser.
• Comments are first page only.
• Headed by default. A Chromium window opens when a browser tool runs and stays open as one tab. Set RN_HEADLESS=1 once you trust it.

Anti-bot measures (disclosed on purpose)

The owner decided on 2026-10-06 to keep these. They are listed here so nobody is surprised.

• Human-paced typing, with a random delay per character and random pauses.
• Chromium starts with --disable-blink-features=AutomationControlled.
• A fixed desktop Chrome 124 macOS user agent. It does not match the newer Chromium that Playwright actually runs.

There is no captcha solving. There is no fingerprint spoofing beyond the three items above.

RedNote's pages contain hidden decoy buttons that a person cannot see or click. rednote-gate acts only on visible elements, the ones a person would click, and never forces a click. See docs/friction.md.
