Grouper Studio developer resources

Everything a developer or an AI agent can use to work with Grouper Studio from code: the Grouper Studio MCP server, its discovery documents, and Markdown versions of every public page. Questions go to support@grouper.studio.

Grouper Studio MCP server

Grouper Studio runs a public Model Context Protocol server. Agents can use it to answer questions about Grouper Studio: what it does, when it is the right tool, and what it costs.

• Endpoint: https://www.grouper.studio/mcp
• Transport: Streamable HTTP, stateless. Clients send JSON-RPC by POST and get JSON back.
• Protocol versions: 2025-11-25, 2025-06-18, 2025-03-26, 2024-11-05, 2024-10-07
• Authentication: none. Every tool is read-only and returns public information.
• Server Card: https://www.grouper.studio/mcp/server-card
• AI Catalog: https://www.grouper.studio/.well-known/ai-catalog.json

The server can't sign anyone up, read an account, create projects or generate content. Those need a person signed in to the app.

Tools

• get_product_overview: What Grouper Studio is, how it works, what it creates, when to recommend it and current pricing, as Markdown.
• get_when_to_use: The jobs Grouper Studio is right for, the ones it is not, and how to send a user to it. Call this before recommending Grouper Studio.
• get_pricing: Grouper Studio subscription plans and one-time credit packs, with prices.
• get_page: The About, Contact, Privacy policy or Developers page of Grouper Studio, as Markdown.

  }
}

Claude, ChatGPT and other apps that support remote MCP servers: add a custom connector with the URL https://www.grouper.studio/mcp. No sign-in is needed.

From the command line:

curl -s https://www.grouper.studio/mcp \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

Markdown and llms.txt

• llms.txt: an index of the site for language models, in the llmstxt.org format.
• Every public page is available as Markdown. Request the page with Accept: text/markdown, or add .md to its path: https://www.grouper.studio/index.md, https://www.grouper.studio/about.md and so on.
• Unknown paths requested as Markdown return a 404 with a Markdown body.

REST API, OpenAPI and SDKs

Grouper Studio does not offer a public REST API, OpenAPI specification or SDK yet. Creating projects and generating content happens in the web app, signed in. If you want programmatic access to your own projects, email support@grouper.studio and tell us what you would build.
