## Description

Running autonomous agents is risky. When one part of your workflow starts failing, it often triggers a domino effect that crashes every other connected service. This MCP acts as a safety valve for your agentic workflows. It uses a deterministic state machine to monitor health and automatically trip a circuit breaker when error rates climb too high. Instead of letting a broken API call loop infinitely or exhaust your resources, this tool shifts the system into a safe state, isolating the problem. You can also use bulkhead isolation to ensure that a failure in one specific type of agent doesn't bleed into your other operations. It's like having a dedicated reliability engineer sitting inside your agent's logic, constantly checking metrics and deciding when to pause, retry, or redirect traffic. By connecting this to your AI client through the Vinkius catalog, you add a layer of industrial-grade fault tolerance that keeps your automated processes stable even when external services go dark.

## Tools

### analyze_health_metrics
Calculates failure rates and downtime to identify when an agent is becoming unstable. It helps you spot critical health issues before they cause a system-wide crash.

### calculate_state_transition
Determines if the circuit should move to an open or half-open state based on current performance. This keeps your error handling deterministic and predictable.

### evaluate_bulkhead_status
Checks if failures are being successfully isolated to specific agent types. It prevents a single bad integration from affecting your entire agent fleet.

### get_operational_strategy
Retrieves the specific fallback behaviors and retry limits for your system. It tells your agent exactly how to react when a service becomes unavailable.

## Prompt Examples

**Prompt:** 
```
The connection to the weather service is failing repeatedly. Should we stop trying to call it?
```

**Response:** 
```
Based on the current error rate, the circuit should move to an **OPEN** state. 

| Metric | Value |
| :--- | :--- |
| Current State | CLOSED |
| Failure Count | 12 |
| Threshold | 10 |
| **Action** | **Trip Circuit** |

I will stop all attempts to reach the weather service to prevent further errors.
```

**Prompt:** 
```
How is the research agent performing compared to the writing agent right now?
```

**Response:** 
```
The system health is currently stable, though there is a slight divergence in performance:

*   **Writing Agent:** 100% success rate (Healthy)
*   **Research Agent:** 85% success rate (Warning)

The Research Agent is currently within its bulkhead limits, so the Writing Agent remains unaffected.
```

**Prompt:** 
```
We've been in an error state for 5 minutes. Is it safe to try the API again?
```

**Response:** 
```
Yes, the timeout period has elapsed. 

I am transitioning the circuit to **HALF_OPEN**. I will allow a limited number of test requests to verify if the service has recovered. If these succeed, we will return to a normal operating state.
```

## Capabilities

### Stop cascading failures
Automatically trips a circuit breaker to prevent a single failing service from crashing your entire agentic workflow.

### Isolate broken components
Uses bulkhead isolation to keep failures contained within specific agent types so the rest of your system stays online.

### Monitor real-time health
Tracks failure rates and downtime to provide a clear picture of how reliable your agents are performing.

### Automate state transitions
Decides exactly when to move between closed, open, and half-open states based on your specific error thresholds.

### Define fallback logic
Sets the rules for how your system should behave and how many times it should retry when things go wrong.

## Use Cases

### Preventing API exhaustion during outages
When a third-party tool goes down, your agent keeps trying to call it. Use calculate_state_transition to trip the circuit and stop the wasted compute.

### Isolating specialized agent failures
If your 'Researcher' agent starts failing, use evaluate_bulkhead_status to ensure your 'Writer' agent keeps working perfectly.

### Automating error recovery
Instead of manual restarts, use get_operational_strategy to let the agent know exactly when it's safe to try a request again.

### Real-time reliability monitoring
An engineer asks their agent for a status report, and the agent uses analyze_health_metrics to provide a precise failure percentage.

## Benefits

- Stop runaway loops by using calculate_state_transition to automatically trip breakers when error thresholds are hit.
- Protect your entire system from single-point failures by using evaluate_bulkhead_status to isolate specific agent types.
- Get clear visibility into system stability by using analyze_health_metrics to track real-time failure rates.
- Standardize how your agents handle errors by using get_operational_strategy to define fallback behaviors.
- Reduce manual intervention by letting the state machine handle the transition between open and closed states automatically.

## How It Works

The bottom line is this MCP provides a programmable safety net that keeps your autonomous agents from spiraling out of control during service outages.

1. Connect the MCP to your AI client via Vinkius
2. Define your error thresholds and bulkhead boundaries
3. The agent uses the state machine to manage real-time reliability

## Frequently Asked Questions

**How does the Agent Circuit Breaker Calculator prevent my agents from crashing?**
It acts as a safety switch. When it detects too many errors, it automatically stops the agent from making further calls to the failing service, preventing a total system collapse.

**Can I use the Agent Circuit Breaker Calculator to isolate specific tasks?**
Yes. It uses bulkhead isolation to ensure that if one specific type of task fails, it doesn't spread to and disrupt your other running processes.

**Will the Agent Circuit Breaker Calculator work with my existing agent workflows?**
Yes, as long as your agent is running in an MCP-compatible client, you can connect this to manage its reliability and error handling.

**How does the Agent Circuit Breaker Calculator decide when to retry a failed task?**
It follows the specific operational strategies you define, managing the transition between states to ensure retries only happen when it's safe and logical.

**Does the Agent Circuit Breaker Calculator help with monitoring agent health?**
Absolutely. It calculates real-time statistical indicators like failure rates and downtime so you can see exactly how stable your agents are.

**What is the purpose of the circuit breaker?**
It prevents an application from repeatedly trying to execute an operation that is likely to fail, protecting the system from cascading failures.

**How does the state transition work?**
You can use `calculate_state_transition` to determine if the circuit should move from CLOSED to OPEN based on failure thresholds, or from OPEN to HALF_OPEN after a timeout.

**How can I check if my agent is at risk of a cascading failure?**
Use the `evaluate_bulkhead_status` tool to analyze if multiple agent types have OPEN circuits, which indicates a cascading risk.
