Server URL
https://mcp.unblockingapi.com/mcpThe key is stored in n8n's credential store, not in the workflow.
The agent decides which pages to read and when to use a template.
Templates return named fields your workflow can map straight into a sheet, CRM or database.
Run the agent on a schedule to watch prices, listings or competitors' pages.
n8n's AI Agent can use tools from any MCP server through the MCP Client Tool node. With UnblockingAPI it gets unblock_fetch and find_templates: the live web through rotating residential proxies and a real browser, and structured data from known sites.
Same hosted URL, authenticated by your key in a header.
https://mcp.unblockingapi.com/mcp, server transport HTTP Streamable.Use unblockingapi to get the Google results for "best espresso machine" as structured data, then summarise the top three.unblock_fetch hands back the full rendered page. For clean fields instead - a price, a title, a whole list - build a template visually in the editor: load the page, tap what you want, done. No CSS selectors to write by hand.
Save it and it's a reusable API endpoint - same account, same key, same as the built-in templates. Build the structure once, then call it from your app - or your AI agent - forever.

UnblockingAPI's server speaks Streamable HTTP. Older n8n versions only had SSE in the MCP Client Tool node; update n8n and choose HTTP Streamable as the transport.
The MCP Client Tool when an AI Agent decides what to fetch. For a fixed workflow step ("fetch this URL with this template"), call the REST API with the HTTP Request node - simpler and just as cheap.
With the key header, the key is stored in n8n's config, so keep that file out of source control. Where sign-in is available it is the safer option: the app then holds only a revocable token, and you can disconnect it under Connected apps.
The MCP server is free and open source. Fetches run on your UnblockingAPI account: every successful fetch costs 1 credit and failed ones are free. New accounts get 500 free credits with no credit card, and plans make credits cheaper at volume. Looking up templates is free.
Three, all read-only. unblock_fetch reads any URL through rotating residential proxies and a real browser, picking a plain fetch or a browser per site by itself. It returns the page as Markdown (HTML on request), or JSON with a template. find_templates checks whether a published template covers a site. get_build_guide gives n8n the API reference and recipes when you build an app on the API. Details on the MCP server page.
The hosted server: nothing to install or update, and most apps sign in without a key. Run it locally with npx -y @unblockingapi/mcp if you prefer to keep the process on your machine - the tools and costs are the same.
