Manifold Markets
Wire your coding agent to Manifold so it can search prediction markets, read odds, and place or manage bets while you validate ideas and forecasts.
Overview
Manifold MCP is an Idea-phase MCP server that lets coding agents search, read, bet on, create, and resolve prediction markets on Manifold Markets.
What is this MCP server?
- Search and read Manifold markets from the agent with stdio MCP transport (v1.0.1).
- Place bets and interact with market positions via MANIFOLD_API_KEY-authenticated tools.
- Create new prediction markets and resolve them from chat-driven workflows.
- Ships as an MCPB package from jbeshir/mcp-servers with one required secret env var.
- Complements manual Manifold browsing when you want reproducible, agent-logged market queries.
- Server version 1.0.1
- Transport: stdio
- 1 required secret: MANIFOLD_API_KEY
What problem does it solve?
Checking Manifold odds and acting on markets from an AI coding session means leaving the agent, copying links, and hand-rolling API calls.
Who is it for?
Indie builders and researchers who already use Manifold and want crowd probabilities inside Claude Code or Cursor during early research.
Skip if: Teams with no Manifold account, jurisdictions or policies that block prediction-market trading, or workflows that only need static competitor notes.
What do I get? / Deliverables
After install, your agent can query live Manifold markets and perform allowed market actions in one thread with your API key.
- Agent-callable tools to search and read Manifold markets
- Bet, create, and resolve market flows driven from the agent
- Documented stdio MCP server entry with required secret env var

Journey fit
Prediction-market data is most valuable early when you are forming beliefs, sizing uncertainty, and researching scenarios before you commit to a build. Research is where external odds and crowd forecasts belong—alongside competitor and audience work—not as a ship-time integration.
How it compares
Live Manifold Markets API bridge via MCP—not an agent skill that invents forecasts without market data.
