# API Key Rotation Manager MCP for AI Agents AI Agent Connect

> API Key Rotation Manager handles the heavy lifting of switching between multiple API keys to prevent rate limit errors. It uses a deterministic circular queue to automatically move to the next available key when one hits a limit or fails, ensuring your LLM orchestrators stay running without manual intervention or constant downtime.

## Description

Running high-volume AI workflows often means hitting rate limits or authentication walls that stall your entire process. Instead of manually swapping keys or writing complex retry logic, this MCP manages a pool of keys for you. It tracks which keys are working and which are currently blocked, automatically cycling to a fresh key the moment a failure is detected. This keeps your agents moving through tasks without getting stuck on a single exhausted account. You can monitor the health of your entire key pool at any time to see how many active keys remain. If a key fails repeatedly, the system automatically pulls it from rotation until it's ready again, preventing your agent from getting caught in a loop of failed requests. By connecting this to your workflow through the Vinkius catalog, you add a layer of resilience that keeps your automated tasks running smoothly even when individual service limits are reached.

## Tools

### get_rotation_status
Check the current health and availability of your API key pool. It shows how many keys are active and which one is currently in use.

### report_key_failure
Tell the system a key failed due to a rate limit or error. This increments the failure count to trigger a rotation.

### report_key_success
Confirm a key worked successfully. This resets the failure counter so the key stays in the rotation.

### rotate_key
Force the system to switch to the next key in the queue. Use this to bypass a blocked or exhausted key immediately.

## Prompt Examples

**Prompt:** 
```
The current API key just hit a rate limit. Rotate to the next one.
```

**Response:** 
```
The system has rotated to the next available key.

| Status | Details |
| :--- | :--- |
| **Current Key ID** | `key_002` |
| **Keys Remaining** | `4` |
| **Action** | Successfully transitioned to next key in queue. |
```

**Prompt:** 
```
Check the current status of the API key rotation pool.
```

**Response:** 
```
Here is the current status of your API key pool:

* **Active Keys:** 5
* **Total Keys in Pool:** 5
* **Current Active Key:** `key_003`
* **System Health:** No exhaustion detected. All keys are performing within normal parameters.
```

**Prompt:** 
```
A request was successful using key_001. Reset its failure count.
```

**Response:** 
```
Success reported for `key_001`.

**Update Details:**
* The failure counter for `key_001` has been reset to **0**.
* The key is now fully eligible for rotation in the primary queue.
```

## Capabilities

### Cycle to a fresh key
Move to the next available key in your pool immediately after a rate limit hit.

### Track key health
Monitor which keys are active and which are currently sidelined due to failures.

### Reset failed keys
Clear error counts for a key once it successfully completes a request again.

### Automate key removal
Automatically stop using keys that hit a specific threshold of consecutive errors.

### Audit pool status
Get a real-time view of how many keys are in your rotation and which one is active.

## Use Cases

### Scaling LLM batch processing
An engineer running a massive data labeling job hits a rate limit on their primary key. The agent detects the failure and immediately switches to the next key to finish the job.

### Autonomous agent reliability
A researcher's agent is performing deep web searches. When an API key gets exhausted, the rotation manager swaps it out so the agent doesn't stop mid-task.

### Multi-account orchestration
A developer managing multiple service accounts uses this to distribute load across several keys, preventing any single account from being throttled.

### Resilient automated testing
A QA engineer's automated test suite uses rotating keys to ensure that testing volume doesn't trigger artificial rate limits during heavy load tests.

## Benefits

- Eliminate workflow stalls by automatically switching to a new key when one hits a limit.
- Reduce manual debugging by letting the system handle key failures in real-time.
- Maintain high availability for long-running agents using a deterministic rotation queue.
- Protect your processes from infinite error loops by sidelining keys that fail too often.
- Get clear visibility into your key pool status to manage your API usage effectively.

## How It Works

The bottom line is that your automated workflows stop breaking every time you hit a service limit.

1. Add your pool of API keys to the rotation manager.
2. Connect your AI client to the MCP via Vinkius.
3. The agent automatically switches keys whenever a rate limit or auth error occurs.

## Frequently Asked Questions

**How does the API Key Rotation Manager prevent my agent from stopping?**
It automatically detects when a key hits a limit and immediately switches to the next available key in your pool, so your agent never has to wait for manual intervention.

**Can I use the API Key Rotation Manager with Claude or Cursor?**
Yes, as long as you are using an MCP-compatible client like Claude, Cursor, or Windsurf, you can connect this to your workflow to manage your keys.

**What happens if all my API keys hit their limits?**
The system will continue to cycle through the pool. If all keys are exhausted or failing, the rotation will stop until you add more keys or reset the failure counts.

**Will this MCP help me manage multiple different API providers?**
This tool is designed to manage a pool of keys for a specific service. You would typically set up separate rotation pools for different providers to keep the logic clean.

**How does the system handle a key that is completely broken?**
The manager tracks consecutive failures. If a key fails too many times in a row, it is automatically removed from the rotation to prevent it from wasting time.

**Is it easy to see which key is currently being used?**
Yes, you can check the real-time status of your pool at any time to see exactly which key is active and how many healthy keys are left.

**How does the rotation mechanism work?**
The system uses a circular queue. When a key fails, you can call `rotate_key` to move to the next valid index in the sequence, ensuring continuous operation.

**How are broken keys handled?**
By using `report_key_failure`, you can track consecutive failures. If a key hits the `maxConsecutiveFailures` threshold, it is automatically removed from the active rotation pool.

**Can I see the current status of my API key pool?**
Yes, you can use `get_rotation_status` to retrieve a snapshot of active keys, total keys, and the current key ID being used.
