Questions it answers
Post Stats reads the public numbers of social posts: views, likes, comments, shares and saves, and when each post went up. It covers YouTube videos and Shorts, TikTok videos and X posts.
Every number says where it came from (the watch page, the channel page, the video page, a free API) and when it was read, and whether the platform rounded it (5.8M is not exact). A number the platform does not show to a logged-out visitor is listed under not_public with the reason, never guessed.
compare_posts ranks up to 10 posts by views, across platforms, with likes per thousand views, so you can see which videos to make more of. list_channel_stats lists the latest posts of a YouTube channel with their views, and a TikTok profile's totals.
On YouTube and TikTok it reads only public pages, as a logged-out visitor would, names itself as PostStats/1.0 (+https://tools.openkrill.app/; support@openkrill.app) and honours robots.txt on the pages it reads. X posts are read through X's public guest API, as the X post reader does. It never signs in, passes a bot check or runs page scripts, spaces out its requests to each platform, and keeps each answer for 15 minutes. When a platform changes its page so the numbers are no longer where the reader looks, the answer is a shape_changed error, not a wrong number.
Free, and nothing about the caller is stored.
The idea behind it, in one live picture: how Post Stats works.
What it can do
- Views, likes, comments, shares, saves and post time of one YouTube, TikTok or X post
- The source and read time of every number, and whether the platform rounded it
- Ranks 2 to 10 posts by views across platforms, with likes per thousand views
- Lists the latest Shorts and videos of a YouTube channel with their views
- Says which numbers a platform keeps private, and why, instead of guessing
Tools
get_post_stats, Get a post's public stats. Read the public numbers of one post: views, likes, comments, shares, saves and the post time, for a YouTube video or Short, a TikTok video, or an X post. Each number comes with its source (which public page or free API), when it was read, and whether the platform rounded it. Numbers the platform keeps private are listed in not_public with the reason. It never signs in, so private posts and account analytics are out of reach.compare_posts, Compare posts by views. Read 2 to 10 public posts (YouTube, TikTok and X can be mixed) and rank them by views, with likes per thousand views for each. Every row has the same fields as get_post_stats; a post that could not be read stays in the list with its error, ranked last.list_channel_stats, List a channel's latest posts. List the latest posts of a YouTube channel with the view count its public channel page shows, newest Shorts first, then videos. For a TikTok profile it returns followers, total likes and video count (TikTok's public profile page lists no videos). X timelines need a login, so an X profile is refused with the reason.
Add Post Stats in ChatGPT
ChatGPT does not read a local config file. A custom MCP server is added in the product, and only after developer mode is on. These steps were checked against OpenAI's plugin connect guide and the ChatGPT MCP guide on 2026-10-01. Developer mode can be hidden by a workspace policy, so a Team or Enterprise admin may have to allow it first.
- Open ChatGPT settings, then Security and login, and turn on Developer mode.
- Open ChatGPT plugins and select the plus button.
- Enter a name such as "Post Stats" and a one-line description of what you want it to answer.
- Under Connection, choose the public endpoint and paste
https://poststats.openkrill.app/mcp. Include the/mcppath. Do not add a tunnel id: this server is already public. - Create the connection and review the tools ChatGPT lists. You should see
get_post_stats,compare_posts,list_channel_stats. The feedback tools on the same server are optional and not required for the lookup. - Start a new conversation, add the connection from the tools menu, and ask: How many views does https://www.youtube.com/shorts/8bE_lGbtjyY have?
No API key and no OAuth client id are required. The server answers without a login. Calls are limited per network and per day, and a limit comes back as a tool error rather than a partial answer. If the tool list is stale after a server change, open the connection and select Refresh, then start a new conversation.
The ChatGPT desktop app, Codex CLI and IDE extension share a different config. In the desktop app, open Settings, then MCP servers, choose Add server, select Streamable HTTP, and paste the same URL. In ~/.codex/config.toml the equivalent is a table named mcp_servers.post-stats with url = "https://poststats.openkrill.app/mcp". ChatGPT on the web does not read that file. A published directory listing is also a different path: this page is the developer-mode connection, not a claim that Post Stats is already in the ChatGPT directory.
Treat the server as untrusted until you have read a few answers. A remote MCP server sees the arguments the model sends. Post Stats is read-only and documents what it sends onward on the privacy page.
If it does not work
The tool does not show up
Check that the endpoint ends in /mcp. Open the connection, select Refresh, then start a new conversation and add the connection from the tools menu. A conversation started before the connection was added does not see its tools.
429 or rate_limited
Each server takes 60 calls a minute from one network, and some tools take fewer. Past that the call comes back as a tool error that starts with rate_limited: wait a minute and ask again. daily_limit means the server reached its shared daily cap, which resets at 00:00 UTC. A limit is not an answer, so do not read it as no results. For higher limits, ask support@openkrill.app for a key.
Developer mode is missing in ChatGPT
Developer mode is in ChatGPT settings, then Security and login, on the web. In a Team or Enterprise workspace an admin can hide it, so ask the admin to allow custom connections first. Without developer mode ChatGPT cannot add a custom MCP server.

Repeat the call yourself if you need a newer reading. Cached answers expire. A rate limit is not a result: wait and try again. Nothing in the call is a ranking, a filing, or advice.
Using it in production
Nothing to install and nothing to run: no package, no Python or Node.js version and no environment variable. Post Stats runs on our servers, and your client only needs the URL https://poststats.openkrill.app/mcp.
| Rate limit | 60 tool calls a minute from one network. initialize and tools/list do not count. |
|---|---|
| Daily cap | 5000 tool calls a day per server, shared by every caller. It resets at 00:00 UTC. |
| At a limit | The call comes back as a tool error that starts with rate_limited (wait a minute) or daily_limit (try after 00:00 UTC), never as a partial answer. |
| Key | None. Do not add an Authorization header or a key field. |
| Higher limits | Email support@openkrill.app with the server name, the calls a day you expect and what they are for. We answer within 1 business day. |
| Freshness | Some answers come from a short cache. Each guide shows the date of its checked call; repeat a call when you need a newer reading. |
| Uptime | Scheduled test calls check the servers through the same endpoint. There is no SLA yet. |
| Data | What each server receives and keeps is on the privacy page. |

Frequently asked questions
How do I install the Post Stats MCP server in ChatGPT?
Turn on Developer mode in ChatGPT settings, then Security and login. In ChatGPT plugins, select the plus button and paste https://poststats.openkrill.app/mcp as the public endpoint. Start a new conversation and add the connection from the tools menu.
Do I need an API key to run Post Stats in ChatGPT?
No. This server takes no API key. For higher limits, email support@openkrill.app with the server name (Post Stats), the calls a day you expect and what they are for. We answer within 1 business day.
What should I do if Post Stats does not connect in ChatGPT?
Check that the endpoint ends in /mcp. Open the connection, select Refresh, and start a new conversation. If Developer mode is missing, a workspace admin has to allow it first.
