Overview

AI-generated overview

Read-only MCP server that lets an assistant search a Japanese X/Twitter sweepstakes dataset and track prize-value changes.

What it does
Exposes the ke-ma.net (懸賞マニア) Japanese sweepstakes dataset through three read-only tools. current_sweep returns the latest sweep matching a keyword, sweep_history returns a time series of matching sweeps, and top_prize_movers lists the largest prize-value movers with an optional up/down filter. Data comes from a bundled snapshot file of ke-ma.net observations.
When to use it
Use it when you want an assistant to look up Japanese X/Twitter sweepstakes campaigns, review how a keyword's sweepstakes changed over time, or see which prizes rose or fell most in value. It suits read-only research over the bundled snapshot rather than live monitoring.
Requirements
Runs locally as a stdio MCP process, started with python server/server.py. Requires Python and the fastmcp package (version 3.0.0 or later). No network access, API key, or account is required; the data is a bundled snapshot file.
Before you install
The dataset is a fixed snapshot dated 2026-10-03, so results may be stale and are not live. The README mentions a revenue-sharing model with a platform fee and external queries, so review how the server is used before relying on it. All tools are read-only and no credentials are requested.

Installation

In SourceWeft

  1. Open Kensho Kema in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

  • No network, no API key, no account required.

Run

bash
python server/server.py          # stdio MCP transport

Requires fastmcp>=3.0.0 (see requirements.txt).

python scripts/pack_mcpb.py

Revenue Model

This MCP Connector follows the Kensho revenue sharing model:

  • 20% to Apify (platform fee)
  • PPE model continues for internal operations
  • Revenue generated from external queries via Apify MCP integration

Integration Notes

The kensho-kema MCP Connector serves as an additional data source for the main Kensho sweepstakes collection, complementing the existing knshow.com, ken-kaku.com, kenshou.club, and cp.meikan.org sources. It provides specialized coverage of the ke-ma.net (懸賞マニア) sweepstakes ecosystem.
