Use AI agents to build an optimized parlay with specified parameters. Agents will analyze rosters, props, and optimize for target multiplier.
AI agents use build_optimized_parlay to commit financial operations through Fantasy MCP — usually the final step of a payment, billing, or trading workflow. A call moves real money.
A parlay is a sports betting construct that combines multiple wagers for a combined payout multiplier. Building an optimized parlay is directly tied to placing financial bets — it recommends specific bet combinations intended to be acted upon for real money. The sibling tools (calculate_kelly_bet_size, get_betting_recommendations, calculate_value_bets) confirm this is a financial betting system.
From the tool's definition 'build an optimized parlay', 'optimize for target multiplier', paired with sibling tools like 'calculate_kelly_bet_size', 'get_betting_recommendations', and 'calculate_value_bets'

It is categorised as a Financial tool in the Fantasy MCP MCP Server, which means it involves financial transactions. Block by default and require explicit approval.
Register the Fantasy MCP server in PolicyLayer and add a rule for build_optimized_parlay: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Fantasy MCP. Nothing to install.
build_optimized_parlay is a Financial tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the build_optimized_parlay rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for build_optimized_parlay. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
build_optimized_parlay is provided by the Fantasy MCP server (mattarm/fantasy_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
