MCP Playground Preview

See what your MCP server looks like as a demo your customers could actually use. Paste the URL and we generate the whole page — overview, example conversations and tools — in about a minute.

Works with streamable HTTP and SSE endpoints, for example https://mcp.example.com/mcp
Used to ground the written overview in what your product actually does. Without it the summary can only describe the tool schemas.
This server needs authentication
Used for this one request and never stored.

Keep this page

Create a free account and this preview becomes a real playground: a permanent address, visitors running your tools live in the browser, an editable write-up, and an embed for your own site.

How it works

link
Paste your server URL

Add your website too if you have one — it makes the generated overview about your product rather than about JSON schemas.

We run the real pipeline

The same generation MCP Showcase runs for paying customers, not a cut-down version. That is the point: a watered-down preview would misrepresent the product.

A written overview, example conversations showing your tools in use, suggested starter prompts, and the full tool list — as a prospect would see it.

What an MCP playground actually is

Your MCP server works. That is not the problem. The problem is that the only artefact you can show someone is a list of JSON schemas, and nobody evaluating a purchase reads JSON schemas. A playground is the page you send instead: what the server does in plain language, example conversations showing an agent using it, suggested things to ask, and the tools themselves, runnable in a browser with nothing installed.

Paste your server URL above and this generates that page from your live server, in about a minute.

What gets generated

  • A written overview — what your server is for, grounded in your website if you give us one. Without a website it can only describe the tool schemas, which is exactly the flat result this page exists to beat, so it is worth adding.
  • Example conversations — realistic exchanges showing your tools being chosen and called, which is what makes the capability legible to a non-developer.
  • Live-chat opening and starter prompts — how the agent would introduce itself and what it would suggest trying first.
  • The full tool list — read live from your server, with descriptions.

This is the real pipeline, not a teaser

Worth being explicit about: the preview runs the same generation MCP Showcase runs for paying customers. It is not a cheaper approximation with the good parts held back. Building a preview that undersold the product would be a strange thing to do — the point is to show you the actual output on your actual server, and let that decide it.

Because it is the real pipeline, it costs real money to run, so there is a small daily limit per visitor. If generation is ever paused, the preview still returns your tools, transport and connect details read live from the server, and says plainly that the written part is missing.

What an account adds

The preview is temporary and read-only. An account turns it into a permanent shareable address, lets visitors actually call your tools live rather than reading examples, makes the overview and the examples editable, gives you an embeddable widget for your own site, and shows you who tried what.

Nothing is stored that should not be

The preview and the server URL are kept so the result has an address you can share, with any credentials in the query string masked out before anything is written. A bearer token you paste is used for that one connection and never reaches our database.

Frequently asked questions

A page where someone can understand and try your MCP server without installing anything: what it does in plain language, examples of an agent using it, and the tools themselves runnable in a browser. It is what you send a prospect instead of a link to your JSON schemas.

Usually under a minute. It connects to your server, reads every tool, optionally reads your website, then writes the overview and the example conversations. The page updates itself when it is done — you do not need to reload.

Yes. It runs the same generation pipeline as a paid playground rather than a cheaper approximation. A preview that undersold the product would be a strange thing to build.

A permanent shareable address instead of a temporary one, visitors able to actually call your tools live, an editable overview and examples, an embeddable widget for your own site, and analytics on who tried what.

The preview and the server URL are stored so the result has a shareable address, with any credentials in the query string masked out first. A bearer token you paste is used for that single connection and is never written to our database.
