Text-only MCP server

KDP Coloring Book Planner

Plan a coloring book from a conversation: what to draw on each page, the title, the cover idea, the Amazon KDP listing and the exact print dimensions. The planner only works with text. It never generates images and never creates or changes anything in your account.

Connect it

The server uses streamable HTTP and OAuth 2.1 with dynamic client registration. You sign in with your KDP Coloring Book Studio account, or create one, when you connect.

Claude

  1. In Claude, open Settings, then Connectors, and choose Add custom connector.
  2. Name it KDP Coloring Book Planner and paste the server URL.
  3. Select Connect, sign in or create an account, and approve read access.
  4. Ask Claude to plan a coloring book. It picks the planner tools on its own.

Other MCP clients

  1. Add a remote MCP server with the URL above.
  2. The client finds the authorization server through /.well-known/oauth-protected-resource/mcp/planner.
  3. Request the books:read scope with the planner URL as the resource.

Five tools, all marked read only. Four of them write text with an AI model; the print specs tool is an exact calculation.

Main inputs: Theme, 3 to 60 pages, audience, difficulty (progressive, easy or detailed), style notes, 0 to 4 recurring characters, language.

Returns: A concept, a line-art style guide, sections, one concrete scene per page with its detail level, and production tips.

Calculate KDP print specs

calculate_kdp_print_specs

Computes the paperback dimensions Amazon KDP expects.

Returns: Full cover size with bleed, spine width, whether spine text is allowed, the barcode area, interior page size with and without bleed and minimum margins, in inches and pixels at 300 DPI.

Exact calculation, no AI

Example prompts

Write as you would to a person. These three cover the main tools.

Plan a 24-page coloring book of cozy cats in a bakery for adults. Start simple and get more detailed toward the end.

Write the Amazon KDP listing for that book, then give me a cover brief with a prompt I can use for the artwork.

What cover size do I need for an 8.5 x 11 coloring book with 100 pages on white paper?

What it can access

  • The connection asks only for the books:read scope, and its token works only on the planner URL.
  • No tool creates, edits or deletes anything in your account, and no tool generates images.
  • You can disconnect at any time from your MCP client's settings, for example Connectors in Claude.

What happens to your data

  • The text of each request is checked by a content moderation service and sent to a text model (OpenAI or Google Gemini) to write the answer.
  • The planner does not save your requests or its answers.
  • For each call we keep the tool name, the MCP client, whether it succeeded (with the error code if not), how long it took and its processing cost, linked to your account.
  • The privacy policy covers the rest, including how to delete your account.

Limits

  • The four tools that use AI share a limit of 10 calls per minute and 100 per day per account. The print specs tool has no limit.
  • Page plans cover 3 to 60 designs. Plans and listings are written in English, Spanish, German, French, Italian or Portuguese.
  • Unsafe requests are refused, and plans and briefs avoid trademarked characters and brands.
  • Answers are suggestions. Check the dimensions and the listing against Amazon KDP's current rules before you publish.
