Server URL
https://mcp.unblockingapi.com/mcpunblockingapi with the URL as serverUrlThe app never sees your API key. Disconnect it any time under Connected apps.
Cascade reads the current API reference instead of recalling an old one.
Client-side apps and dashboards come back complete, not as an empty shell.
The MCP config is global, so the tools follow you into every workspace.
Cascade's own web tools stall on pages that render with JavaScript or sit behind bot protection. unblock_fetch takes a plain fetch first and a real browser when needed; find_templates turns known sites into JSON.
Paste the hosted URL and approve access. No key to copy, nothing to install.

}Same hosted URL, authenticated by your key in a header.

}When you need the contents of a URL, use the unblock_fetch tool from the
unblockingapi MCP server instead of the built-in web tools. Leave render unset.
Before parsing a recognisable site by hand, call find_templates with the URL and
pass a matching template to unblock_fetch to get JSON.find_templates and come back with parsed results instead of HTML.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.

Open it from Cascade: the … menu in the Cascade panel → MCPs → Open MCP config file. The location has changed between versions, so this is the reliable way in. Remote servers use serverUrl.
Save the file and refresh the MCPs list in the Cascade panel, then switch the server on. On team plans with an MCP allowlist, the server id (unblockingapi) has to be allowlisted first.
Not when you sign in. Windsurf gets an access token for the hosted server, and the server uses your key on its behalf, so the key itself never leaves UnblockingAPI. You can disconnect any time under Connected apps. If you connect with an API key header instead, the key is stored in Windsurf's own config.
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 Windsurf 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.
