WHAT IT DOES

What pm_create_market does on Basis MCP Server

AI agents use pm_create_market to create or update resources in Basis MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Basis MCP Server environment.

RISK

Why pm_create_market is rated Medium

The tool creates and stores a new prediction market record, which is a reversible operation (markets can be deleted or modified post-creation). This is a Write operation. Severity is high because prediction markets can involve financial stakes and user funds, and a malicious actor could create markets designed to defraud or mislead participants.

From the tool's definition Tool name 'pm_create_market' and description 'Create a private prediction market with metadata' indicate the tool creates a new data structure (a prediction market) with associated metadata.

pm_create_market Rate-limited

pm_create_market stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
