## Description

JSONBin.io lets your AI agent handle cloud-based JSON storage without you having to build a backend. It's perfect for storing configuration files, mock data, or app states. You can create bins, organize them into collections, and query specific fields using JSON Path. It handles everything from tiny snippets to 10MB XL bins, making it a reliable place for your agent to persist data between sessions. Imagine you're building an app and need a place to dump configuration data or save the state of a user's session. Usually, you'd have to spin up a database, set up endpoints, and worry about authentication logic. This Connector changes that by giving your agent a direct line to cloud storage. Instead of manual copy-pasting, your agent can grab a specific config value, update a user's preferences, or pull a whole set of mock data for testing. It handles the heavy lifting of cloud storage so you can stay focused on the logic. Because Vinkius makes it so easy to connect these tools, you can jump from a blank chat to a fully persisted data environment in minutes. You're not just asking an agent to remember something for one turn; you're giving it a persistent memory that lives outside the chat window. Whether you're a developer prototyping a new feature or an analyst querying processed results, this setup ensures your data stays organized, versioned, and accessible whenever you need it.

## Tools

### count_bin_versions

Modifies the actual JSON content of a bin. This is how you update your stored data.

### update_collection_name
Renames an existing collection. Use this to rename your project folders.

### fetch_uncategorized_bins
Finds all bins that haven't been put in a collection. Use this to find orphaned data.

### list_access_keys
Shows all the keys you've created. This lets you manage who has access to your bins.

### add_schema_to_collection
Links a schema to a collection for validation. This ensures all bins in a folder follow the same rules.

### update_schema_name
Renames a saved JSON schema document. Use this to keep your schema labels accurate.

### update_schema
Modifies the contents of a JSON schema document. Use this to change your data validation rules.

## Prompt Examples

**Prompt:** 
```
I need to store a mock user profile for a 'premium' tier. Use JSONBin.io to create a private bin named 'PremiumUser' with some fake data.
```

**Response:** 
```
I've created a private bin named 'PremiumUser'. Here is the Bin ID: `72a...`. I've stored the profile with details like a premium badge, a high loyalty score, and a list of favorite categories.
```

**Prompt:** 
```
Can you check the 'AppConfig' bin and tell me what the current 'theme' color is?
```

**Response:** 
```
Checking the 'AppConfig' bin... The current theme color is set to `#2c3e50` (Midnight Blue). Would you like me to update it to something else?
```

**Prompt:** 
```
List all the collections I have in my JSONBin.io account.
```

**Response:** 
```
I found the following collections in your account:
* Production-Configs
* Staging-Data
* Archive-Bins
Which one would you like to explore?
```

## Capabilities

### Create and delete JSON bins
Store and remove JSON objects from the cloud instantly.

### Organize bins into collections
Group your data into logical folders for better project structure.

### Fetch data using JSON Path
Query specific nested fields instead of pulling the entire file.

### Track changes with versioning
Keep a history of your data and roll back to previous states.

### Store large files up to 10MB
Handle bigger datasets using the XL bin feature.

### Manage private and public visibility
Control who can see your data with simple privacy toggles.

### Generate and manage access keys
Create restricted keys to give your agent specific permissions.

## Use Cases

### Mocking API Responses
A developer wants the agent to store a set of fake user profiles to use as a mock backend for a frontend demo.

### Configuration Management
An engineer needs to store various environment variables and UI themes in create_bin for different deployment stages.

### Data Analysis
An analyst wants the agent to save a large JSON result set and then use read_bin to query specific nested fields.

### Workflow State
An automation specialist uses update_bin to save the progress of a multi-step task so the agent can resume it later.

## Benefits

- Persistent memory for your agent means it won't forget your app's state between different chat sessions by using read_bin and update_bin.
- Use read_bin with JSON Path to grab exactly what you need instead of pulling massive objects into your context window.
- Organize your projects using create_collection to keep your configuration files from becoming a mess.
- Keep a history of your data with versioning so you can roll back to previous configurations if an update breaks something.
- Handle massive datasets with create_xl_bin when your standard JSON files hit the 10MB limit.
- Secure your data by using create_access_key to give your agent specific permissions without sharing your master key.

## Frequently Asked Questions

**What is JSONBin.io MCP for AI agents?**
It's a way to give your AI agent a permanent place to store and retrieve JSON data. Instead of the agent forgetting things as the conversation gets longer, it can save data to the cloud and pull it back whenever it needs it.

**Can I use JSONBin.io MCP to store large files?**
Yes, you can use the XL bin feature to store JSON files up to 10MB. This is great for handling larger datasets that would normally be too big for a standard chat prompt.

**Is my data secure with JSONBin.io MCP?**
You have full control over privacy. You can set bins to be private or public, and you can use access keys to give your agent specific, restricted permissions to your data.

**How does JSONBin.io MCP handle versioning?**
Every time you update a bin, the Connector can track those changes. This allows you to see previous versions of your data and ensures you don't lose important information if an update goes wrong.

**Can my agent query specific parts of a JSON file?**
Yes, it uses JSON Path. This means your agent can grab just one specific field or a small array from a large file, which saves space in your chat window and keeps the agent focused.

**Do I need to set up a database to use JSONBin.io MCP?**
No, that's the main benefit. You don't need to manage a database server or write backend code. You just connect the Connector, and your agent has immediate access to cloud storage.

**Can I filter the data inside a bin without downloading the whole JSON?**
Yes. When using the `read_bin` tool, you can provide a `json_path` expression to filter the data on the server side and retrieve only the matching subset.

**How do I store datasets larger than the standard bin limit?**
You should use the `create_xl_bin` tool. This is specifically designed for large JSON files (up to 10MB) and requires a paid JSONBin.io plan with Early Access enabled.

**Is it possible to change a bin from public to private after creation?**
Absolutely. Use the `update_bin_privacy` tool with the target `bin_id` and set `is_private` to true or false as needed.
