Scenariosim is a remote MCP server that gives an AI agent 6 tools, among them break_even, compare_scenarios, health_check. It answers at https://scenariosim-mcp.pages.dev/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 22 October 2026, succeeded.
Deterministic what-if & scenario simulation for AI agents: projections, sensitivity & break-even.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
break_even | Solve for the input value required to make an output metric hit a target value (deterministic bisection root-finding). Provide 'template', 'solve_for' (the input to solve), 'target_metric' (defaults to the primary output), and 'target_value Inputs: template, inputs, solve_for, target_metric, target_value, bounds |
compare_scenarios | Run 2-3 scenarios and compare their key_results side by side, with deltas against the first (baseline) scenario. Provide a 'scenarios' array where each entry is {name?, template, inputs} (each may set its own horizon, or pass a shared top-l Inputs: scenarios, compare_metric, goal, horizon, include_projections |
health_check | Server health, version, and capabilities (tools, templates, period labels, max horizon). No parameters. |
list_templates | Discovery tool: list every pre-built scenario template (id, label, category, description, primary output, documented inputs with defaults/units, and available output metrics), plus how to run a custom free-form scenario and the supported pe |
run_scenario | Main simulation tool. Run a deterministic what-if projection from a pre-built template (saas_growth, pricing_change, churn_impact, cost_reduction, hiring_plan, cash_runway, unit_economics, marketing_funnel, compound_growth) OR a free-form ' Inputs: template, inputs, metrics, horizon, period_label |
sensitivity_analysis | Vary one or more input assumptions and show the impact on a target output metric (one-at-a-time sensitivity).

It answered our last check on 22 October 2026 in 154 ms. Over 6 checks since 11 September 2026 it answered 6. Status here comes from Neuronto's own probes, not from the publisher.
6, as returned by the server's own tools/list on 14 September 2026: break_even, compare_scenarios, health_check, list_templates, run_scenario, sensitivity_analysis.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://scenariosim-mcp.pages.dev/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
