Overview

AI-generated overview

Lets an assistant run and compare LLMs and generate images or video, returning the real yen cost of each call.

What you can do
FastMetal is a remote MCP server for running and comparing language models and for generating images and video. According to the registry description, each call returns the actual yen cost incurred. The manifest lists no individual tools, so the exact tool set is not documented here.
When to use it
Worth adding when an assistant needs to call or benchmark several LLMs, or produce image and video output, and you want per-call cost visibility in yen. Less useful if you only need a single fixed model or no generative media.
Requirements
A remote streamable HTTP endpoint at Authentication is required: a bearer token sent in the Authorization header, using a FastMetal API key created in the FastMetal dashboard. No local runtime or packages are declared.
Before you install
The Authorization header carries a FastMetal API key, so treat it as a secret and avoid exposing it in logs or shared configuration. Calls consume paid credits; the provider recommends creating a key with a spend cap in the dashboard to limit spending. Prompts and generation requests are sent to a third-party service.

Installation

In SourceWeft

  1. Open FastMetal in the dashboard and add it to a workspace.
  2. Connect Authorization token credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/ai.fastmetal%2Ffastmetal/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

This server asks for a credential such as an API key, so SourceWeft could not read its tools without one and has not indexed them.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
