Simmer
Connect coding agents to Simmer prediction markets for research briefings, autoresearch, skill discovery, and optional paper or live trading.
Overview
Simmer MCP is a MCP server for the Build phase that connects agents to prediction-market skill discovery, autoresearch, and paper-or-live trading via Simmer.
What is this MCP server?
- npm package simmer-mcp via npx (stdio transport, v3.3.2)
- Free-tier tools without API key; Pro tools need SIMMER_API_KEY (sk_live_...)
- simmer_trade with paper/sim by default; live only if SIMMER_MCP_ALLOW_LIVE=true
- Skill discovery, autoresearch, and execution for prediction markets
- Published from SpartanLabsXyz/simmer-sdk; product site simmer.markets
- npm package version 3.3.2 (simmer-mcp)
- Registry MCP version 3.3.2
- Pro tools gated by SIMMER_API_KEY

What problem does it solve?
You want agents to research and act on prediction markets but lack a standard MCP bridge with safe defaults for simulated versus live trades.
Who is it for?
Advanced indie builders building agent experiments around prediction markets who accept sim-first defaults and manual live-trade gating.
Skip if: Casual users seeking regulated brokerage integrations, guaranteed returns, or zero-config financial advice without oversight.
What do I get? / Deliverables
After npx simmer-mcp and optional API keys, your agent can run Simmer briefings and trades in sim mode until you explicitly enable live execution.
- MCP-connected Simmer briefings and autoresearch outputs
- Paper or sim trades by default via simmer_trade
- Optional live trade execution when allow-live env is set
Recommended MCP Servers
Journey fit
Financial and market APIs are integrated during Build when you wire agent tooling and external data sources into your stack. integrations is the shelf for third-party trading and market MCP servers—not core app frontend or generic PM docs.
How it compares
Prediction-market execution MCP via Simmer, not a generic stock ticker or personal budgeting skill.
Common Questions / FAQ
Who is Simmer MCP for?
Developers wiring Claude Code or Cursor to Simmer for prediction-market research, autoresearch, and controlled paper or live trading workflows.
When should I use Simmer MCP?
Use it while building agent tooling or quantitative side projects that need Simmer briefings and trade tools—not as a substitute for legal or investment compliance review.
How do I add Simmer MCP to my agent?
Run npx simmer-mcp with stdio in your MCP config, set SIMMER_API_KEY for Pro tools if needed, and set SIMMER_MCP_ALLOW_LIVE=true only when you intend live simmer_trade execution.
