ChatGPT + Wayfern

ChatGPT answers from the page, not from memory.

  • Remote MCP with OAuth
  • ChatGPT asks before each tool call
  • Credits come from your Wayfern balance
Set it up Create an account

ChatGPT browses, but sites that block bots return a challenge page, and the answer comes from memory.

With Wayfern as a plugin, ChatGPT calls Wayfern tools. Each tool runs in an anti-detect browser and returns markdown, JSON or an image URL. ChatGPT shows each call before it runs.

A ChatGPT chat. The user types @ and picks the Wayfern plugin, then asks for a price table. ChatGPT asks to run a Wayfern tool, the user allows it, and a table of three prices comes back.

Setup

Add Wayfern as a custom MCP plugin.

Do this one time, in ChatGPT on the web.

    Open Plugins

    Go to chatgpt.com/plugins. Click the plus button, then Add custom MCP server.

    Enter the server

    Name it Wayfern. Under Connection, paste the server URL. Set Authentication to OAuth.

    URL

    https://api.wayfern.com/mcp
  3. 3

    Create the plugin

    Read the risk warning. Click I understand and want to continue, then Create as a plugin.

  4. 4

    Install and sign in

    Install the plugin from your personal plugins. ChatGPT opens wayfern.com. Sign in and click Allow.

  5. 5

    Mention it in a chat

    Type @ and pick Wayfern, then ask.

    prompt

    @Wayfern Read the pricing pages of Linear, Height and Plane. Make a table of the price per seat for each plan.

Route

ChatGPT reaches Wayfern over the remote server.

ChatGPT connects only to public remote MCP servers. It cannot send a custom header or run commands on your computer, so OAuth is the one route.

Remote MCP OAuth sign-in
Best fit
OAuth sign-in on wayfern.com. ChatGPT asks you to confirm tool calls.
MCP + token Authorization header
No
ChatGPT has no field for a custom Authorization header.
Agent skill SKILL.md
No
A chat has no shell to run curl.
REST API api.wayfern.com/api/v1
No
ChatGPT does not call REST APIs on its own.

Example tasks

Questions for a chat

  • 01

    Compare prices

    “Read the pricing pages of these four tools and make a table of the monthly price for 10 seats.”

    scrape_page reads each page for 1 credit.

  • 02

    Brand colours

    “Get the brand colours and fonts of stripe.com and give them to me as CSS variables.”

    brand_profile costs 10 credits for a domain.

  • 03

Tools

What ChatGPT can call

The same tools on every route, at the REST API rates. Every result reports credits_charged.

All tool inputs
  • scrape_page Fetch one page through an anti-detect browser and return clean markdown, HTML, links and metadata. The screenshot, pdf and json formats add +4 credits (once); summary adds +2. 1 credit / page
  • extract_data Extract structured data from one or more pages with a prompt and an optional JSON Schema. Re-running over pages already fetched is free. 1 credit / uncached source page
  • map_site List a site's URLs from its sitemaps and page links. 2 credits / 10 URLs
  • capture_screenshot Capture a clean image of a page: cookie banners and ads removed, lazy images loaded, tall pages captured end to end. Returns a short-lived download URL and an artifact key, not image bytes. Slices of a full page cost nothing extra; a fail_if_contains match is not charged. 5 credits / capture
  • brand_profile Identity, colours, logos, social links and company metadata for a domain. 10 credits / profile
  • site_styleguide Colours, typography, spacing, radii, shadows and the design tokens a site declares. 10 credits / site
  • site_fonts Font families, where each is served from, available weights, file formats and where they are used. 5 credits / site
  • crawl_site Start a bounded multi-page crawl. Returns a job id immediately and charges nothing up front; pages are billed as the crawl runs. 1 credit / successful page
  • crawl_status Poll a crawl started with crawl_site and read a page of its results. The pages were billed as they were crawled. Free
  • search_web Search Google, Bing, and DuckDuckGo. Returns ranked results, ads, provider failures, pagination, and related queries. 2 credits / provider page
  • list_search_engines List live provider ids and labels. Free
