This MCP server provides a high-performance statistical simulation engine to compare different D&D character attribute generation methods. By executing 10,000 randomized iterations per method, it allows AI agents to analyze the mathematical 'power' and consistency of mechanics like heroic_4d6, classic_33d6, point_buy, and standard_array. Users can use tools like simulate_method to generate datasets, analyze_attribute_averages to find mean scores, and evaluate_power_threshold to determine the probability of high-strength character creation. It is an essential tool for tabletop RPG designers and players looking to understand the impact of different rolling mechanics on character strength.

4 tools expose this connector's capabilities to your AI agent.

simulate_method

Executes a large-scale randomized simulation for a specific generation method

analyze_attribute_averages

Calculates the mean value for each attribute across a provided set of simulation results

generate_method_comparison_report

Produces a high-level comparative summary between two different simulation datasets

evaluate_power_threshold

Determines the probability of a character "outperforming" a specific power metric

Run a simulation for the heroic 4d6 method and show me the average strength.

The simulation for `heroic_4d6` is complete. The calculated average strength across 10,000 iterations is 12.38.

What is the probability of getting at least two attributes of 15 or higher using the classic 3d6 method?

Using the `classic_3d6` dataset, the probability of having at least 2 attributes with a score of 15 or higher is 4.2%.

Compare the power of point buy versus standard array.

The comparison report shows that `point_buy` results in a higher average for primary attributes, while `standard_array` provides more consistent baseline scores across all six attributes.

You can simulate `heroic_4d6`, `classic_3d6`, `point_buy`, and `standard_array` methods.

Bezos Flywheel Prover MCP

1 tools Official

A startup benchmarked against 5 competitors instead of talking to a single customer. It proposed standalone initiatives instead of a flywheel. It built an end-user product instead of infrastructure. It formed a committee instead of a two-pizza team. It optimized for this quarter instead of a 7-year thesis. That is not strategy — that is a project list. This tool forces five Bezos-level axes: customer obsession, flywheel design, infrastructure-first, Day 1 culture, and long-term compounding.

AI Ethics Prover MCP

1 tools Official

An AI said 'AI should be fair and transparent' without naming a single affected group. It said 'we checked for bias' without naming a metric, attribute, or measured disparity. It said 'contact support' as the recourse mechanism. That is not ethics — that is ethics washing. This tool forces five operational axes: stakeholder identification, harm quantification, bias auditing, transparency demonstration, and recourse mechanisms.
