Oracle3

Build prediction-market agents that discover markets, analyze opportunities, and test strategies.

Connect AI agents to Kalshi and Polymarket through MCP. Give them reusable Skills for market research and strategy development, then build on a Python engine for paper and live execution.

13 MCP tools · 6 agent Skills · Kalshi & Polymarket data · Python 3.10+

Why Oracle3

• A connected research workflow. Discover contracts, inspect their rules and order books, compare related outcomes, and track simulated positions.
• Calculations that include trading costs. Five relationship checks return candidate baskets, per-leg fees, and calculated net edge.
• Tools and workflows for agents. Use MCP for structured access and Skills for repeatable research, strategy authoring, and operations.
• An engine you can extend. Build strategies with Python interfaces, risk controls, and paper/live venue adapters.
• A foundation for experiments. Reproducible software checks, automated tests, and installed-package validation make the implementation inspectable.

Public Kalshi and Polymarket market reads need no exchange credentials. MCP provides market data, calculations, and a local paper ledger; real-order execution uses the separate CLI/Python engine.

Quickstart

Install the current development checkout:

git clone https://github.com/YichengYang-Ethan/oracle3-prediction-market-agent.git
cd oracle3-prediction-market-agent
python -m venv .venv
.venv/bin/python -m pip install -e .

Connect it to Claude Code from this directory:

claude mcp add oracle3 -- "$PWD/.venv/bin/oracle3-mcp"

For other MCP clients, configure the absolute path to .venv/bin/oracle3-mcp as the command with an empty argument list. On Windows, use .venv\Scripts\python.exe and .venv\Scripts\oracle3-mcp.exe.

Give your agent a first task

Find Kalshi and Polymarket contracts about the next Fed rate decision. Compare their outcome definitions, resolution rules, and order-book quotes. Summarize the markets with their IDs, prices, and the assumptions needed to compare them.

For a calculation that works offline after installation:

Use Oracle3 to check an implication: A implies B. A has a YES bid of $0.60 and B has a YES ask of $0.55. Use the default Kalshi taker fee schedule and 100 contracts per leg. Show the basket, gross edge, fees, and net edge.

The synthetic example returns $5.00 gross edge − $3.4125 fees = $1.5875 calculated net edge, conditional on the supplied implication and quotes. See exact inputs and output.
