# Consensus Round Calculator MCP for AI Agents AI Agent Connect

> Consensus Round Calculator MCP simulates Raft consensus algorithm behavior. It lets you calculate quorum requirements, predict leader election timings, check for split votes, and verify log replication consistency across distributed clusters.

## Description

Building distributed systems is hard because consensus is unpredictable. This MCP gives your agent the ability to run deterministic simulations of the Raft algorithm to catch logic errors before they hit production. Instead of guessing if a cluster of seven nodes will reach agreement during a network partition, you can run a simulation to see exactly how the election plays out. You can check if your quorum math is right, predict how long an election will take based on network latency, and verify that log entries are being committed correctly across all nodes. It turns abstract distributed systems theory into a practical testing tool for your agent. Since this is part of the Vinkius catalog, you can connect it to your preferred AI client and start running these simulations immediately without setting up a local environment.

## Tools

### simulate_election
Evaluates the current state of an election to see if a leader is chosen or if a split vote happens. It helps you catch election failures in your distributed logic.

### validate_log_replication
Checks if log entries are being committed correctly or if there are consistency errors. It ensures your data stays synchronized across the cluster.

### get_quorum_threshold
Calculates the minimum number of nodes required to reach consensus. It prevents errors in setting up cluster membership.

### estimate_election_timing
Predicts the duration of a leader election based on network conditions. It helps you tune timeouts for better stability.

## Prompt Examples

**Prompt:** 
```
How many nodes do I need for a quorum in a 9-node cluster?
```

**Response:** 
```
For a 9-node cluster, you need a quorum of **5 nodes** to reach consensus or elect a leader.
```

**Prompt:** 
```
Will my election succeed if I have 5 nodes and only 2 can communicate?
```

**Response:** 
```
No, the election will likely fail. 

| Metric | Value |
| :--- | :--- |
| Total Nodes | 5 |
| Quorum Required | 3 |
| Available Nodes | 2 |

Since you only have 2 nodes available, you cannot meet the required quorum of 3, meaning no leader can be elected.
```

**Prompt:** 
```
How long will an election take with 7 nodes, a 300ms timeout, and 50ms RTT?
```

**Response:** 
```
The estimated election duration is **225.0ms**. This calculation accounts for the specified network round-trip time and your timeout settings.
```

## Capabilities

### Calculate quorum requirements
Find the exact number of nodes needed to reach agreement in a cluster.

### Predict election outcomes
Determine if a leader will be successfully elected or if a split vote will occur.

### Estimate election duration
Calculate how long a leader election will take based on specific network round-trip times.

### Verify log consistency
Check if log entries are being committed correctly across all distributed nodes.

## Use Cases

### Testing cluster resilience
An engineer asks their agent to simulate an election with 5 nodes where 2 are offline to see if the remaining 3 can still form a quorum.

### Tuning election timeouts
A developer uses the tool to see how a 150ms timeout affects election speed when network latency jumps to 100ms.

### Validating log consistency
A system architect checks if a specific sequence of log entries will be successfully committed across a 7-node cluster.

### Designing new clusters
A designer calculates the exact quorum needed for a 9-node deployment to ensure high availability during maintenance.

## Benefits

- Catch split vote errors early by using simulate_election to test cluster states.
- Avoid configuration mistakes by using get_quorum_threshold to verify majority requirements.
- Optimize network timeouts by using estimate_election_timing to predict election durations.
- Prevent data corruption by using validate_log_replication to check entry consistency.
- Reduce manual math errors when designing cluster sizes and membership rules.

## How It Works

The bottom line is you get a reliable way to test Raft consensus logic through natural language commands.

1. Connect your AI client to the MCP through the Vinkius platform.
2. Provide your cluster configuration, such as node count and network latency, to your agent.
3. Receive deterministic simulation results for elections and log replication.

## Frequently Asked Questions

**Can I use Consensus Round Calculator to test my production cluster?**
No, this MCP is designed for deterministic simulations. It helps you model and test theoretical scenarios and logic before you apply them to real-world systems.

**Does this work with consensus protocols other than Raft?**
The logic in this MCP is specifically built for the Raft consensus algorithm. It won't accurately simulate Paxos or other protocols.

**How does this help with election timeouts?**
You can use it to predict how long an election will take based on your specific network latency, helping you set more stable timeout values.

**Can I check if my cluster configuration is valid?**
Yes, you can use it to verify that your quorum thresholds and node counts are mathematically sound for the cluster size you've chosen.

**How do I simulate a split vote?**
You can run an election simulation with specific node states to see if the votes will be distributed such that no single node reaches a majority.
