Overview

AI-generated overview

Remote MCP endpoint for sealed prediction-market verdicts graded in public across Polymarket and Kalshi, with no authentication required.

What you can do
  • The listing gives no tool list, so capabilities are known only from the description.
  • It is described as serving sealed prediction-market verdicts.
  • Those verdicts are graded in public across Polymarket and Kalshi.
  • It is a remote streamable HTTP endpoint with no authentication.
When to use it
Worth considering when you want an assistant to consult prediction-market verdicts covering Polymarket and Kalshi, or to check how such calls were graded publicly. Because no tools are documented, verify what it actually exposes before relying on it.
Requirements
A remote streamable HTTP endpoint; nothing to install locally. No authentication, environment variables or headers are declared. Network access to the endpoint is required.
Before you install
No tools, README or instructions are published, so what the server exposes and what data it receives cannot be verified. The description mentions no credentials, payments or write actions, but treat any betting-related content as informational rather than financial advice.

Installation

In SourceWeft

  1. Open Spoiler 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.zerozaky%2Fspoiler/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
