Solves the internal rate of return for an equal-period cash flow series by deterministic bisection over a declared rate bracket with declared tolerance and iteration cap. Never Newton/derivative-based, so no float-drift nondeterminism. Reports whether the bracket contained a sign change and whether the search converged.
Copy this paragraph into Claude, OpenClaw, or any MCP-aware agent to run this exact tool, with this sample, and verify the artifact.
Run the AINumbers MCP tool `compute_irr`. Task: Internal rate of return for an equal-period cash flow series, solved by deterministic bisection over a declared rate bracket with declared tolerance and iteration cap.
Call it with arguments: {"policy_parameters":{"cash_flows":[{"amount":-1000},{"amount":500},{"amount":400},{"amount":300},{"amount":100}]}}
Verify before trusting: call `verify_execution_hash` on mcp.ainumbers.co (https://mcp.ainumbers.co/mcp) with the parameter `claimed_hash` set to the returned `execution_hash`, passing the full artifact the run returned (the object containing `policy_parameters` + `output_payload` + `execution_hash`; equivalently `policy_parameters` + `output_payload` with `claimed_hash`), not the bare hash string.
