# Execution Circuit Breaker MCP for AI Agents MCP

> Execution Circuit Breaker stops your agents from hitting dead ends. It monitors consecutive errors and automatically pauses execution when things go wrong, preventing a chain reaction of failures across your automated workflows.

## Description

The Execution Circuit Breaker prevents your agents from repeatedly attempting operations that are likely to fail. When an error occurs, the system tracks it. If failures pile up, the circuit trips to an open state, which blocks all calls for a set cooldown period. This keeps your automation from wasting resources or hammering broken services. You can check if execution is still permitted or notify the system when a task succeeds to reset the failure count. By using this through Vinkius, you add a layer of resilience that protects your entire agentic ecosystem from cascading outages.

## Tools

### get_circuit_status
Checks if the circuit is currently allowing execution or if it is blocked. This helps your agent decide whether to proceed with a task.

### record_failure
Notifies the system that an attempt failed so it can track error counts. Use this whenever an operation does not complete as expected.

### record_success
Tells the system of a successful run to reset any failure tallies. This allows the circuit to close again after a period of stability.

## Prompt Examples

**Prompt:** 
```
Is it safe to run the data sync right now?
```

**Response:** 
```
The circuit is currently in the **CLOSED** state, so execution is permitted. You can proceed with the synchronization task.
```

**Prompt:** 
```
I just got an error on the payment gateway. Update the status.
```

**Response:** 
```
I have recorded that failure. If this reaches the threshold, all further attempts will be blocked for the cooldown period to protect your system.
```

**Prompt:** 
```
The sync finished without any issues.
```

**Response:** 
```
Great. I have updated the registry with a success, which resets your consecutive error count to zero. The circuit remains closed and ready for the next task.
```

## Capabilities

### Stop error loops
Automatically pauses execution after repeated failures.

### Monitor system health
Tracks whether it is safe to proceed with tasks.

### Auto-reset logic
Clears failure tallies once a successful operation occurs.

### Prevent resource drain
Blocks calls during cooldown periods to save compute.

## Use Cases

### API Outage Protection
An agent tries to call a broken service, hits the threshold, and stops trying until the service is back up.

### Database Stress Reduction
When queries start failing due to load, the circuit trips to prevent further database pressure.

### Cost Control
Prevents your agent from burning through tokens by repeatedly attempting doomed operations.

## Benefits

- Avoid infinite loops by automatically pausing tasks when errors pile up.
- Protect downstream APIs by tracking consecutive error counts.
- Reduce manual monitoring since the system handles cooldowns itself.
- Maintain clean logs by preventing a flood of repetitive error messages.
- Restore operations instantly when a successful run resets the failure count.

## How It Works

The bottom line is that it prevents a single point of failure from crashing your entire automation pipeline.

1. Connect the MCP to your agentic workflow or client.
2. Configure your agent to report every success and failure.
3. The circuit automatically blocks execution if error thresholds are met.

## Frequently Asked Questions

**How does Execution Circuit Breaker prevent API overload?**
It monitors failure rates and blocks all calls once a threshold is reached, protecting your downstream services from being overwhelmed.

**Can I use Execution Circuit Breaker with Claude or Cursor?**
Yes, any MCP-compatible client like Claude, Cursor, or Windsurf can use this to manage execution permissions for your agents.

**Does Execution Circuit Breaker help with cost management?**
Absolutely. By stopping failed loops, it prevents unnecessary token usage and compute costs during service outages.

**How do I know if the circuit is open?**
You can check the current operational state to see if execution is currently permitted or if a cooldown is in progress.

**What happens after the cooldown period ends?**
The system enters a state where it allows trial executions to see if the underlying issue has been resolved.

**What does it mean when the circuit is in an OPEN state?**
An OPEN state means the failure threshold has been reached, and all execution attempts are currently blocked to allow for a cooldown period.

**How can I check if I am allowed to execute a task?**
You should use the `get_circuit_status` tool. It will return whether the state is CLOSED, OPEN, or HALF_OPEN and provide a `shouldExecute` flag.

**Does this system use real-world time?**
No, the system uses a deterministic integer-based tick counter to ensure all state transitions are perfectly reproducible in testing environments.
