Overview

AI-generated overview

SunsetDiff lets an assistant look up AI model shutdown dates, official replacements and migration diffs, and scan text for deprecated model ids.

What you can do
Look up a model's status, dates, replacement and source by model id, and list models with a shutdown date inside the next N days. Get the migration diff for a model, defaulting to its official replacement. Scan free text to find known model ids that are deprecated or shutting down.
When to use it
Useful when maintaining code, configs or documentation that reference AI model ids and you need to know which are being retired, when, and what to migrate to.
Requirements
A remote streamable HTTP endpoint; no API key, environment variables or headers are declared.
Before you install
The server is read-only lookup and scanning; no credentials are requested. Results depend on the service's own model data, so verify critical migration decisions against the cited source.

Installation

In SourceWeft

  1. Open SunsetDiff 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/com.sunsetdiff%2Fsunsetdiff/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

83% 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.
