Prompt Perfect provides tools that improve and refine prompts for AI workflows, including a browser extension, a ChatGPT-based assistant, and image-focused tooling. Its website presents these products as ways to get clearer prompts and better AI outputs.
Prompt Perfect exposes a public HTTP API documented by an OpenAPI spec at `https://promptperfect.xyz/openapi.json`, plus a cataloged MCP server at `https://chatgpt.promptperfect.xyz/mcp` whose authentication appears required but is not publicly documented on the site.

Point your MCP client at the server URL and approve access in the browser. The server supports OAuth Dynamic Client Registration (RFC 7591), so the client registers itself automatically — no developer-portal app, client_id, or client_secret to create.
