# AutoPlugin
AutoPlugin is a Python package that makes it easy to convert Python functions into [ChatGPT plugins](https://openai.com/blog/chatgpt-plugins). With just a couple lines of code, you can:
- Automatically create an OpenAPI spec with custom endpoints for your registered Python functions, telling ChatGPT how to use it. Pull endpoint descriptions from the function docstring or generate them automatically with the OpenAI API.
- Generate the `ai-plugin.json` file to register your plugin with ChatGPT.
- Launch a local server that can be used by ChatGPT for development.
## Installation
To install AutoPlugin, simply run the following command:
```bash
pip install autoplugin
```
To install with the ability to generate endpoint descriptions for the OpenAPI specification automatically from source code, install with
```bash
pip install 'autoplugin[gen]'
```
## Basic Usage
To get started with AutoPlugin, follow these steps:
1. Import the necessary functions from AutoPlugin:
```python
from autoplugin import register, generate, launch, get_app
```
2. Create an app instance, backed by FastAPI:
```python
app = get_app()
```
3. Use the register decorator to register your functions as API endpoints.
AutoPlugin will automatically generate descriptions if needed.
```python
@register(app, methods=["GET"])
async def get_order(name: str) -> str:
order = await get_order_from_db(name)
return f"Order for {name}: {order}"
# Generated description: "Retrieves an order from the database for a given name."
```
4. Generate the necessary files (`openapi.yaml` and `ai-plugin.json`) for your ChatGPT plugin.
Optionally, specify `out_dir` to change where they're saved to:
```python
# generated files saved to `.well-known/` directory
generate(app, name="Example", description="Plugin to add numbers or greet users")
```
5. Launch the server. Optionally, specify `host` and `port`:
```python
launch(app) # API hosted at localhost:8000
```
6. Follow the [instructions](https://platform.openai.com/docs/plugins/getting-started/running-a-plugin) to run a custom plugin:
- On ChatGPT, make a new chat.
- Under "Models" select "Plugins"
- In the Plugins dropdown, select "Plugin store"
- Click "Develop your own plugin"
- Enter the URL you're running the server at ("localhost:8000" by default) and hit enter.
- Click "Install localhost plugin"
## Example
Here's a complete example that demonstrates how to use AutoPlugin to create API endpoints for two functions, `hello` and `add`.
It also generates the `openapi.yaml` and `ai-plugin.json` files, by default in the `.well-known` directory. :
```python
from autoplugin.autoplugin import register, generate, launch, get_app
app = get_app()
@register(app, methods=["GET", "POST"])
async def hello(name: str, age: int = 5) -> str:
return f"Hello, {name}! Age {age}."
@register(app, methods=["GET"])
async def add(a: int, b: int) -> int:
""" Adds two numbers """
return a + b
# Generate the necessary files
generate(app, name="Example", description="Plugin to add numbers or greet users")
# Launch the server
launch(app)
```
This example creates a FastAPI server with two endpoints, `/hello` and `/add`, that can be accessed using GET or POST requests.
AutoPlugin will use the docstring for the OpenAPI description of `/add` and generate an automatic description for `/hello` by passing the source code of the function to OpenAI's API.
## The `@register` Decorator
The `@register` decorator is used as follows:
```python
@register(app: FastAPI,
methods: List[str], # which HTTP methods to support
description: Optional[str], # if provided, used as is
generate_description: Optional[bool]) # whether to autogenerate a description
def my_func(...):
...
```
AutoPlugin generates function descriptions in the OpenAPI spec so that ChatGPT knows how to use your endpoints. There are a few keyword arguments to customize the behavior of this generation
By default, the description is fetched from the docstring. If there's no docstring, or if you specify `generate_description=True`, AutoPlugin will generate one automatically from OpenAI's API (requires the LangChain package and setting the `OPENAI_API_KEY` environment variable).
Finally, you can override the description generation behavior by specifying a description (e.g. if the docstring contains extra information not needed in the OpenAPI description) in the `description` keyword argument.
## The `generate` Function
The `generate` function has the following signature:
```python
def generate(app: FastAPI, out_dir: str=".well-known", **kwargs):
```
The `out_dir` keyword argument determines where the `ai-plugin.json` and `openapi.yaml` files are saved upon generation.
All other keyword arguments are used to customize fields of the [plugin manifest file](https://platform.openai.com/docs/plugins/getting-started/plugin-manifest).
The `name` keyword argument can be used for convenience to update both `name_for_human` and `name_for_model` at once. Same for `description`. In a future update, these can be automatically generated to further streamline the deployment process. Keep in mind the [best practices](https://platform.openai.com/docs/plugins/getting-started/writing-descriptions) for descriptions.
## Testing
AutoPlugin also provides a `testing_server` utility (courtesy of [florimondmanca](https://github.com/encode/uvicorn/issues/742#issuecomment-674411676)) for testing your endpoints. Here's an example of how you can use it to test the `/hello` and `/add` endpoints from the example above:
```python
from autoplugin.testing import testing_server
from os.path import join
import requests
def test_api():
host = "127.0.0.1"
port = 8000
server, base_url = testing_server(host=host, port=port, app_file="path/to/example.py", app_var="app")
with server.run_in_thread():
# Server is started. Do your tests here.
response = requests.post(join(base_url, "hello"), json={"name": "John Doe", "age": 31})
assert response.json() == {"result": "Hello, John Doe! Age 31."}
response = requests.get(join(base_url, "hello"), params={"name": "Jane Smith"})
assert response.json() == {"result": "Hello, Jane Smith! Age 5."}
response = requests.get(join(base_url, "add"), params={"a": 6, "b": 8})
assert response.json() == {"result": 14}
# Server will be stopped.
test_api()
```
