SimBroker MCPB v0.2.0 (demo paper broker)

SimBroker is a pretend broker for the PolyBridge Market Foresight cookbook. It records simulated fills to local files only. It has no market connection, no credentials, no network access, no real trading, and no financial advice.

New in v0.2.0: every account starts with a simulated $1,000 SPY starter position, so the demo always has a position to add to, exit, or hold.

Install the bundle in Claude Desktop alongside the read-only PolyBridge MCPB.
