Overview

AI-generated overview

A remote MCP endpoint that lets an assistant route high-complexity questions, such as coding or hard reasoning tasks, to an external answering service.

What you can do
Fortytwo MCP is a remote, streamable HTTP MCP server reached at a hosted endpoint. Its stated purpose is to answer high-complexity questions where the best possible answer is required, including coding and hard reasoning. The manifest does not list individual tools, so the exact tool names and inputs are not documented here. Paid tool calls are indicated by the payment header described in the manifest.
When to use it
Consider it when you want an assistant to hand off difficult questions, such as coding problems or demanding reasoning tasks, to a separate hosted service rather than answering locally. It is less relevant for routine queries or for workflows that must stay entirely on your own machine.
Requirements
A remote MCP client that supports streamable HTTP, plus network access to the hosted endpoint. No local package or runtime is declared. For paid tool calls, the X-PAYMENT header is required; the manifest describes it as an x402Escrow payment header using USDC on Base or Monad. No accounts, environment variables, or other credentials are declared.
Before you install
The X-PAYMENT header carries payment credentials and is required for paid tool calls, so calls may spend funds; treat the header value as a secret and check pricing before use. Questions and any content sent with them go to a third-party hosted service, so avoid submitting sensitive or confidential material. The manifest lists no tools, so verify what the server actually does before relying on it.

Installation

In SourceWeft

  1. Open Fortytwo MCP in the dashboard and add it to a workspace.
  2. 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/network.fortytwo%2Ffortytwo-mcp/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.

Score

28% of the applicable checks met

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.
