Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Descripción del creador (original en inglés)
Kalshi and Polymarket data, venue fees, no-arbitrage checks and paper execution for AI agents.
Estos tres nunca se combinan en una sola puntuación: las opiniones, las mediciones y la popularidad son cosas distintas.
Todavía no escribimos un resumen sencillo para este. Abajo están los datos que leímos del registro.

Superó 1 de 1 revisiones básicas aplicables. No hemos leído el código. Antes de agregar una clave o un token, revisa qué acceso pide el servidor y usa una clave que tenga solo los permisos que necesitas.
El registro no indica ninguna clave obligatoria, aunque algunos servidores te piden iniciar sesión la primera vez que los usas.

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+
Quickstart · MCP tools · Agent Skills · Project and contributions · Documentation
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.
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.
Client configuration and first tool call · Published-package installation
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.
| Task | Tools | Result |
|---|---|---|
| Discover markets | search_markets, get_market | Contracts, metadata, and available resolution rules |
| Inspect market conditions | get_quote, get_orderbook | Prices, fee information, and displayed depth |
| Analyze related contracts | check_constraint, check_constraint_live | Baskets and net edge under a stated relationship |
| Calculate fees and model values | trading_fee, fair_value | Fee estimates and parameterized model outputs |
| Try a paper entry | paper_order, paper_portfolio | Simulated fills and holdings in a local ledger |
Relationship checks cover implication, exclusivity, complement, same event, and event sum. They expose assumptions with their results, giving agents and researchers a common calculation layer.
All 13 MCP tools · Workflow examples
The repository includes six workflows that help agents move from individual tool calls to complete tasks:
| Skill | Use it to |
|---|---|
| Data discovery | Find markets and organize research inputs |
| Constraint arbitrage | Examine related contracts and calculate fee-aware baskets |
| Quant strategy authoring | Develop strategies with Oracle3's Python interfaces |
| Agent strategy authoring | Build agent-driven decision workflows |
| Paper operations | Run and inspect simulated trading sessions |
| Live operations | Configure and operate the separate live engine |
Claude Code project copies are included in .claude/skills/. Open the checkout as your project, or use your client's supported Skill installation mechanism. Skill setup.
For AI agents: start with llms.txt for task routing, the MCP reference for tool schemas, and AGENTS.md for contributing code.
Use the same project for research scripts, agent strategies, and engine operations:
.venv/bin/oracle3 market search --exchange kalshi --query "fed" --json
.venv/bin/oracle3 market search --exchange polymarket --query "fed decision" --json
| Component | Build with it |
|---|---|
| MCP server | Structured market access and local paper operations for agents |
| Relations and fees | Shared calculations for related-contract strategies |
| Strategies | Logical-relation, statistical, and model-driven approaches |
| Trading engine | Paper/live adapters for Kalshi, Polymarket, and Solana via DFlow |
| Pricing | Wang-transform models and estimators for research |
| oracle3-extras | Optional venue, data-provider, and wallet integrations |
CLI guide · Integration guide · Execution reference
Oracle3 combines a concrete decision environment with structured tools, observable state, and a software validation harness. This supports work on agent interfaces, workflow guidance, and reproducible evaluation.
CI runs automated tests and checks the built package through real MCP sessions on SDK 1.x and 2.x. The harness documentation explains the reproducible checks. Model-level agent evaluation is a next research direction.

Oracle3 began as ulab-uiuc/oracle3, developed by Yicheng Yang and Haofei Yu at U Lab (University of Illinois Urbana-Champaign). It also bundles the lab's Coinjure package. Yicheng Yang continues to develop and maintain the extensions in this repository. Read the project story and contributions.
We acknowledge the foundational work of the Coinjure team at the University of Illinois Urbana-Champaign—Haofei Yu, Yicheng Yang, Yuxiang Liu, and Prof. Jiaxuan You—on which Oracle3 builds.
