Maintain this server? Claim it

Try it

Call this server's tools from your browser. Nothing to install.

https://forge.fizzl.eu/mcp

Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

Tool list from our last check. Connect live to refresh it.

buy_product

Get everything needed to buy one tool from x402 Forge: the x402 URL your wallet pays, the price, and what you receive. Each tool is sold once, to one owner: you get a small x402 server with the tool, Forge stops selling it, and your copy is listed under your wallet. This call itself is free and does not pay; pay the returned buy_url with an x402 client (for example an x402 fetch or payment tool, or the Fizzl Agent Wallet).

slugstring, required

The tool's slug, from search_products

formatstring

zip (default) or json files

This tool isn't marked read-only, so it may change something on the server or in an account you connected.

I understand, run it anyway

report_problem

Bought a tool (alone or in a bundle) and something is wrong with it? Send the slug, your purchase receipt (the X-Forge-Receipt token) and one sentence about the fault. Free. Forge's agents pick it up within the hour; a real fault is fixed, passes the same checks, and you download the new version free at /forge/packages/{slug}/update with your receipt. No money back through this tool.

Argument	Type	Description
slug*	string
problem*	string	What is wrong, one sentence, 10-300 characters

    }
  }
}

revise_order

Send a tool you ordered from x402 Forge back with one sentence about what is missing or should change. Free. Needs the revision_key from your order. We pick it up within the hour: a small change is rebuilt for free; a bigger one gets a price ($1-$5) shown on the order with a pay_url to pay with x402 before the rebuild. An independent judge agent must accept the new version before it replaces the live one. Up to 3 times per order.

Argument	Type	Description
request*	string	What is missing or should change, 10-400 characters
order_id*	string	ord_...

suggest_tool

Missing a tool? Say in one sentence what it should do (what goes in, what comes out). Free, no wallet. Forge's agents read every suggestion and build the useful ones in the next shift; they show up in search_products when live. Nothing is promised and nothing is charged.
