Overview

AI-generated overview

A remote MCP server that gives an assistant Kindle publishing niche data — demand, competition, BSR and revenue estimates — with paid lookups via x402 USDC on B

What you can do
List KDP niche keywords ordered by demand score, with a configurable result limit, at no cost. Retrieve detailed niche intelligence for a specific keyword: demand score, competition score, Amazon BSR range, estimated monthly revenue, review threshold, average book pricing and data freshness.
When to use it
Useful when researching Kindle publishing opportunities and comparing niches by demand, competition and estimated revenue before choosing what to write.
Requirements
A remote endpoint at nichedata.dev over streamable HTTP; no account, API key or environment variables are declared. Detailed niche lookups are paid per request in USDC on the Base network through x402, so a compatible wallet or payment setup is needed.
Before you install
The research_niche tool charges money per request (priced in USDC on Base), so repeated calls spend funds; check pricing tiers before use. The free list_niches tool requires no payment. No authentication is declared for the endpoint.

Installation

In SourceWeft

  1. Open KDP Niche Research 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.simul813%2Fkdp-niche-research/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

Get detailed KDP niche intelligence for a specific keyword. Returns demand score, competition score, Amazon BSR range, estimated monthly revenue, review threshold, average book pricing, and data freshness for the given Kindle publishing niche. Pricing tiers (x402 USDC on Base network): - $0.03 per query for cached/pre-seeded keywords - $0.10 per query for live on-demand research (new keywords) Use the free `list_niches` tool first to see available keywords. Payment options: 1. Set the KDP_X_PAYMENT environment variable on the server for auto-pay. 2. Pass a valid x402 payment header via the x_payment argument. 3. If neither is set, the tool returns structured 402 payment instructions that an x402-capable agent can use to construct and retry payment.

Takes precedence over the KDP_X_PAYMENT environment variable.
