Flipcoin
Let your coding agent quote, trade, and create prediction markets on Base via FlipCoin without hand-rolling wallet and API flows.
Overview
FlipCoin MCP is a MCP server for the Build phase that lets agents trade, quote, and create prediction markets on Base through FlipCoin’s API.
What is this MCP server?
- stdio MCP server (@flipcoin/mcp-server v0.1.2) for agent-first prediction markets on Base
- Trade, get quotes, and create markets through MCP tools instead of custom REST clients
- Requires FlipCoin agent API key (fc_ prefix) from flipcoin.fun/agents
- npm registry transport for local agent configuration
- Built for autonomous agents trading structured event markets, not manual-only dashboards
- Server version 0.1.2 on npm as @flipcoin/mcp-server
- Single required secret env: FLIPCOIN_API_KEY
- stdio transport; one npm package entry in server manifest
What problem does it solve?
Hooking an agent up to prediction markets usually means bespoke API and key handling that breaks every time you switch hosts or models.
Who is it for?
Indie builders prototyping agent-driven trading or market-making workflows on Base who already have or can obtain a FlipCoin agent key.
Skip if: Teams that need regulated brokerage features, no crypto exposure, or production trading without reviewing FlipCoin’s terms and chain risks.
What do I get? / Deliverables
After you register the server with FLIPCOIN_API_KEY, your agent can call FlipCoin market actions through standard MCP tools in one config block.
- Registered FlipCoin MCP server in the agent config
- Callable MCP tools for quote, trade, and market operations on Base
- Documented env var setup for local and CI agent runs

Journey fit
MCP wiring lands in Build when you connect agent tooling to external financial APIs as part of the product or automation stack. Integrations is the canonical shelf for third-party MCP servers that expose remote trading and market-creation capabilities to Claude Code, Cursor, or Codex.
How it compares
On-chain prediction-market MCP integration, not a generic DeFi wallet or back-office accounting skill.
