## Description

Fastn lets you manage your backend logic without leaving your chat interface. If you're tired of jumping between your code editor and a separate dashboard to trigger flows, this Connector handles that for you. You can tell your agent to run a specific process, check why a previous run failed, or update your flow definitions on the fly. It handles the heavy lifting of API calls and credential management, so you can focus on the logic. By adding this to your Vinkius setup, you give your agent the ability to interact with your low-code backend as if it were a first-class citizen of your workspace. You can audit your platform usage, see what's currently running, and manage your secrets without ever opening a browser tab. It turns your backend into a conversational tool where you can deploy, monitor, and debug your infrastructure as fast as you can type. Imagine being able to tell your agent to check the status of our payment flow and getting a full breakdown of the last five executions, including exactly where a failure occurred. Or tell it to update the production flow to use the new API endpoint and have it happen instantly. This isn't just about running commands; it's about having a live link to your backend that understands your business logic. You can rotate keys to keep things secure, archive old versions to keep your workspace clean, and monitor your daily quotas to ensure you're staying within your plan. It moves the friction of backend management out of the dashboard and into your primary workspace.

## Tools

### list_workflows
See all your flow definitions in one list. This gives you a bird's-eye view of your backend.

### get_credentials
Pull stored secrets for your connectors. This makes it easy to access keys without manual hunting.

### get_execution
See exactly what happened at every step of a specific run. This helps you find bugs in seconds.

### get_quota_daily
Check your daily limits at a glance. You'll always know how much usage you have left.

### get_quota_summary
Get a high-level view of your account usage. This is great for a quick check on your plan status.

### get_quota_usage
See how much of your plan you've used so far. Use this to stay under your monthly caps.

### list_executions
See the history of runs for a specific tenant. Use this to audit past activity.

### get_workflow
View the full spec of a specific flow. This lets you inspect the logic of any definition.

### publish_workflow
Deploy a flow to your production environment. This moves your logic live with one command.

### rotate_credentials
Refresh your connector keys automatically. This keeps your integrations secure and up to date.

### store_credentials
Save new connector keys securely. This ensures your secrets aren't sitting in plain text.

### update_workflow
Change the logic of an existing flow. Use this to modify your backend without re-creating it.

### archive_workflow
Turn off a flow without deleting it. This is perfect for deactivating old logic.

### cancel_execution
Stop a flow that's currently running. Use this to kill processes that are hanging or stuck.

### create_workflow
Build a new flow definition from scratch. This lets your agent help you draft new logic.

### execute_flow
Run a flow immediately using a specific JSON payload. This is the primary way to trigger your backend logic.

## Prompt Examples

**Prompt:** 
```
Show me the step-by-step execution trace for ID 'exec_789xyz' in tenant 'main-prod'.
```

**Response:** 
```
Fetching trace for 'exec_789xyz'...

**Execution Summary:**
- **Status:** Success
- **Total Duration:** 450ms
- **Steps:**
  1. Auth (Success)
  2. Fetch Data (Success)
  3. Transform (Success)
  4. Load (Success)

Everything looks good! The data was processed and loaded successfully.
```

**Prompt:** 
```
Execute the 'data-sync' flow with input { "source": "crm" }.
```

**Response:** 
```
Executing 'data-sync'...

**Result:**
- **Status:** Completed
- **Records Synced:** 150
- **Source:** CRM

The synchronization is finished. Would you like me to pull the full execution trace for this run?
```

**Prompt:** 
```
List all flow definitions for tenant 'main-prod'.
```

**Response:** 
```
I've retrieved the workflows for 'main-prod'. You have 3 active flows:

| Flow Name | Status |
| :--- | :--- |
| payment-process | Active |
| send-welcome-email | Active |
| data-sync | Active |

Which one would you like to inspect or run?
```

## Capabilities

### Trigger backend flows
Run specific processes instantly with custom JSON payloads.

### Manage flow definitions
Create, update, and publish your backend logic via chat.

### Inspect execution traces
View step-by-step logs to find exactly where a flow failed.

### Secure credential management
Store, retrieve, and rotate API keys for your connectors.

### Monitor platform usage

## Use Cases

### Debugging a failed CRM sync
A DevOps engineer asks the agent to show the trace for a specific sync ID to see which step failed.

### Triggering a new user onboarding flow
A product manager asks the agent to run the welcome flow for a new test user with a specific payload.

### Rotating expired API keys
A developer asks the agent to refresh the credentials for the payment gateway connector to prevent downtime.

### Auditing production logic
An engineer asks the agent to list all active flows to ensure the correct versions are live.

## Benefits

- Stop switching tabs to trigger logic; do it directly from your chat interface.
- Debug complex flows in seconds by viewing detailed execution traces for every step.
- Keep your secrets safe by automating credential rotation and secure storage.

## How It Works

The bottom line is you get a natural language interface for your entire Fastn backend.

1. Connect your Fastn API Key and Space ID in your settings.
2. Link the Connector to your preferred client through Vinkius.
3. Ask your agent to run, list, or debug your backend flows.

## Frequently Asked Questions

**Can the Fastn MCP run my backend flows using natural language?**
Yes. You can tell your agent to trigger specific flows by describing the action or providing the necessary data. It handles the API communication for you.

**How does the Fastn MCP help with debugging?**
It allows your agent to pull detailed, step-by-step execution traces. You can ask why a specific run failed and get a breakdown of every step instantly.

**Is it safe to manage API keys with the Fastn MCP?**
Yes. The Connector includes tools to store and rotate credentials securely. This keeps your secrets out of your prompts and your agent's conversation history.

**Can I use Fastn MCP to see my platform usage?**
Absolutely. You can ask your agent for a summary of your usage, your daily breakdown, or your current plan limits without leaving your chat.

**Does Fastn MCP support deploying new flows?**
Yes. You can use the agent to publish new flow definitions to your production environment or archive old ones to keep your backend organized.

**Can I stop a flow that is currently hanging?**
Yes. If a process is stuck, you can ask your agent to cancel the execution immediately to free up your resources.

**Can I trigger a flow and get the result immediately?**
Yes. Use the `execute_flow` tool with the flow name and input data. It performs a real-time sync execution and returns the response directly to the agent.

**How can I debug a failed flow execution?**
You can use `list_executions` to find the ID of the failed run, then use `get_execution` to retrieve a full step-by-step trace of what happened during that specific execution.

**Is it possible to update an existing workflow definition?**
Absolutely. The `update_workflow` tool allows you to modify the JSON definition of any flow. Remember to use `publish_workflow` afterwards to deploy your changes to the live environment.
