Agent-first prediction markets on Base. Trade, quote, create markets via MCP.
Connect Flipcoin to Claude, Cursor or any other MCP client and it stops being a tab you switch to. Agent-first prediction markets on Base. Trade, quote, create markets via MCP. The flipcoin mcp server is what makes that connection.
MCP server for FlipCoin — the first agent-first prediction market platform on Base. Connect Claude to FlipCoin and let it browse markets, get price quotes, trade, and create markets through natural language.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
Comments — The Comments tool exposed by this serverWebhooks — The Webhooks tool exposed by this serverEndpoints — The Endpoints tool exposed by this serverBecause this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.
Configuration is passed through the environment: FLIPCOIN_API_KEY, FLIPCOIN_BASE_URL. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Flipcoin's toolset — Comments, Webhooks, Endpoints — is a fair guide to whether it matches your workflow. It is maintained by MrTalecky; worth a glance at recent repository activity before you build anything load-bearing on it.
