Overview

AI-generated overview

A remote MCP server that checks AI-generated work against stated requirements and returns structured verdicts, findings and repair steps.

What you can do
Submit AI work together with its requirements and receive a structured verdict on whether it meets them, with findings and suggested repair steps. Use a free preview tool without credentials, or supply a tenant key for authenticated use.
When to use it
Useful when you want an assistant's output reviewed against explicit requirements before accepting it, and you want a structured pass/fail result with concrete fixes rather than free-form commentary.
Requirements
A remote endpoint at ultimate-critic.fly.dev over streamable HTTP; no local runtime or package. An X-API-Key header is needed for tenant access; omitting it uses the free preview tool.
Before you install
The X-API-Key header is a secret tenant key and should be kept private. The work and requirements you submit are sent to a third-party hosted service, so avoid sending confidential material unless that is acceptable.

Installation

In SourceWeft

  1. Open The Ultimate Critic 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/io.github.marksignals%2Fthe-ultimate-critic/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

Score

39% 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.

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

    A hosted service is used under its provider's terms, so no license is expected here. This check is left out of the percentage.
