Questions it answers
Page Fetch reads one public web page and returns its main content as clean Markdown, with the page title, description, language, canonical address and a list of the links in the content.
It keeps headings, paragraphs, lists, quotes, code blocks, tables, emphasis and links, with every link made absolute. Menus, headers, footers, side columns, scripts, cookie banners and hidden text are left out, so an agent reads the page and not the site around it.
robots.txt is read before every page, and a page it disallows for PageFetch or for all crawlers is not read; the answer says why. Each site is read at most once a second (more when its robots.txt asks), at most 300 times a day, and a page read in the last 60 minutes is answered from the stored copy with no new request. The reader names itself as PageFetch/1.0 (+https://tools.openkrill.app/; support@openkrill.app).
It reads only public pages. It does not sign in, pass a paywall, solve a CAPTCHA or run page scripts, so a page built only by script comes back short with a note. PDFs and images are refused.
Each page's Markdown is kept for 60 minutes so a repeat call does not reach the site again, then deleted. Nothing about the caller is stored.
What it can do
- Turns one public web page into clean Markdown with absolute links
- Keeps headings, lists, quotes, code blocks and tables; drops menus, footers and banners
- Returns up to 100 distinct links from the main content, marked internal or external
- Checks robots.txt before every page and says why a page was not read
- Returns the title, description, language and canonical address of the page
Tools
fetch_page, Fetch a web page as Markdown. Read one public web page and return its main content as clean Markdown: headings, paragraphs, lists, quotes, code blocks, tables and absolute links, without menus, footers, scripts or cookie banners. Also returns the title, description, language, canonical address and up to 100 links from the content. robots.txt is checked first and a disallowed page is skipped with the reason. It never signs in, passes a paywall, solves a CAPTCHA or runs page scripts. Pass max_chars for more than 20000 characters.
Add Page Fetch 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 "Page Fetch" and a one-line description of what you want it to answer.
- Under Connection, choose the public endpoint and paste
https://pagefetch.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
fetch_page. 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: Read https://example.com as Markdown.
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.page-fetch with url = "https://pagefetch.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 Page Fetch 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. Page Fetch 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.

RFC 9309 is the robots.txt standard, a public page whose text does not change, so the Markdown can be checked against it. The request below was posted to https://pagefetch.openkrill.app/mcp as tools/call. HTTP 200. Source: the Page Fetch server, read 2026-10-11.

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. Page Fetch runs on our servers, and your client only needs the URL https://pagefetch.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 Page Fetch 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://pagefetch.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 Page Fetch in ChatGPT?
No. This server takes no API key. For higher limits, email support@openkrill.app with the server name (Page Fetch), the calls a day you expect and what they are for. We answer within 1 business day.
What should I do if Page Fetch 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.
