Plugins
Short answer: Plugins are the data-and-tools layer of Questflow’s financial harness — the finance equivalent of MCP servers for a coding agent. They give the AI Finance Agent market prices, on-chain flow, news, social sentiment, prediction-market odds, and research so skills are not guessing in the dark.
What a plugin is
A plugin is a connector: read a venue, a data vendor, or a research tool, and return structured context the agent can use. It does not place the trade. That is execution.
Data the harness is built to ingest
Market data
Prices, books, OHLCV, funding, open interest, liquidations
Regime, trigger, execution quality
On-chain
Wallets, transfers, holders, unlocks, whale prints
Crypto positioning and cycle
News & calendars
Headlines, macro events, earnings, unlocks
Catalysts and invalidation
Social / attention
CT, narrative heat, smart-money chatter
Reflexivity — used with care
Prediction markets
Polymarket odds, liquidity, resolution timing
Event thesis, not just spot
Portfolio context
Balances, positions, PnL across connected accounts
The agent must know your book
Deep research
Filings, protocol docs, long-form research
Quality/forensic skills
Venue-native reads (same rails as execution)
These are both plugins (read) and, where permitted, execution venues (write):
Hyperliquid — perps, leverage, funding, OI, liquidation risk, vault activity
Polymarket — positions, probabilities, liquidity, catalysts
OKX / OKX DEX — balances, spot/DEX activity, routing, CEX vs DEX exposure
Lighter — perps book, fees, whether it is the better venue for a fill
Account-aggregation plugins (portfolio context)
The harness is designed to read books you already have, then advise or execute only where you grant write access:
Wallet address
Hyperliquid and other public on-chain books
Zero-auth Day-1 context
Coinbase
Crypto balances and history
Official OAuth read
Binance
Crypto balances, positions, trades
User API key, read-only first
Plaid
US brokers (Robinhood, Webull, Fidelity, Schwab, E*TRADE, banks)
Global portfolio picture
SnapTrade
Broker aggregation (IBKR, Alpaca, Webull, …)
Dev-style broker read
IBKR TWS
Multi-market positions
Pro book context
Futu / moomoo OpenD
HK / A-shares / US
Greater-China book
Read is not a trade. Write stays on execution accounts you authorize.
How plugins compose with the other pillars
A Druckenmiller-style skill is useless without liquidity and rates context. A VCP skill needs clean price/volume. A Willy Woo skill needs on-chain. The model only reasons over what plugins feed it.
