Gpusmarket

Gpusmarket is a remote MCP server reached over the older SSE transport, at https://mcp.gpusmarket.com/sse. Clients that support remote servers generally still accept SSE endpoints, though the protocol now favours Streamable HTTP.

The registry entry declares an HTTP header for the connection: Authorization (secret). A secret header usually carries an API key or token issued by the service; clients that accept custom headers set it with the server's URL.

It can also run locally from a Node.js package published to the npm registry: gpusmarket version 2.4.16. It speaks MCP over stdio, so the client starts it as a program and talks to it through standard input and output. It needs Node.js; clients usually start it with npx — the usual command is npx -y gpusmarket@2.4.16. It reads the environment variable GPUSMARKET_API_KEY (required, secret); set it in the client's configuration for this server.

In the mcpServers JSON format that many desktop and editor MCP clients read, the entry looks like this (placeholders in angle brackets):

{
  "mcpServers": {
    "gpusmarket": {
      "command": "npx",
      "args": [
        "-y",
        "gpusmarket@2.4.16"
      ],
      "env": {
        "GPUSMARKET_API_KEY": "<secret>"
      }
    }
  }
}
