🎸 Plug and Plai
Plug and Plai is an open source library aiming to simplify the integration of AI plugins into open-source language models (LLMs).
It provides utility functions to get a list of active plugins from plugnplai.com directory, get plugin manifests, and extract OpenAPI specifications and load plugins.
Installation
You can install Plug and Plai using pip:
pip install plugnplai

Quick Start Example

OAuth Plugins Example for setting up plugins with OAuth: examples/oauth_example
Usage
Get a list of plugins


urls = get_plugins(): Get a list of available plugins from a plugins repository.


urls = get_plugins(filter = 'ChatGPT', category='dev'): Use 'filter' or 'category' variables to query specific plugins


Example:
import plugnplai

# Get all plugins from plugnplai.com
urls = plugnplai.get_plugins()

# Get ChatGPT plugins - only ChatGPT verified plugins
urls = plugnplai.get_plugins(filter = 'ChatGPT')

# Get working plugins - only tested plugins (in progress)
urls = plugnplai.get_plugins(filter = 'working')

# Get plugins by category - only tested plugins (in progress)
urls = plugnplai.get_plugins(category = 'travel')

# Get the names list of categories
urls = plugnplai.get_category_names()

Utility Functions
Help to load the plugins manifest and OpenAPI specification

manifest = get_plugin_manifest(url): Get the AI plugin manifest from the specified plugin URL.
specUrl = get_openapi_url(url, manifest): Get the OpenAPI URL from the plugin manifest.
spec = get_openapi_spec(openapi_url): Get the OpenAPI specification from the specified OpenAPI URL.
manifest, spec = spec_from_url(url): Returns the Manifest and OpenAPI specification from the plugin URL.

Example:
import plugnplai

# Get the Manifest and the OpenAPI specification from the plugin URL
manifest, openapi_spec = plugnplai.spec_from_url(urls[0])

Load Plugins
Example:
from plugnplai import Plugins

###### ACTIVATE A MAX OF 3 PLUGINS ######
# Context length limits the number of plugins you can activate,
# you need to make sure the prompt fits in your context lenght,
# still leaving space for the user message

# Initialize 'Plugins' by passing a list of urls, this function will
# load the plugins and build a default description to be used as prefix prompt
plugins = Plugins.install_and_activate(urls)

# Print the deafult prompt for the activated plugins
print(plugins.prompt)

# Print the number of tokens of the prefix prompt
print(plugins.tokens)

Example on installing (loading) all plugins, and activating a few later:
from plugnplai import Plugins

# If you just want to load the plugins, but activate only
# some of them later use Plugins(urls) instead
plugins = Plugins(urls)

# Print the names of installed plugins
print(plugins.list_installed)

# Activate the plugins you want
plugins.activate(name1)
plugins.activate(name2)
plugins.activate(name3)

# Deactivate the last plugin
plugins.deactivate(name3)

Prompt and Tokens Counting
The plugins.prompt attribute contains a prompt with descriptions of the active plugins.
The plugins.tokens attribute contains the number of tokens in the prompt.
For example:
plugins = Plugins.install_and_activate(urls)
print(plugins.prompt)
print(plugins.tokens)

This will print the prompt with plugin descriptions and the number of tokens.
Parse LLM Response for API Tag
The parse_llm_response() function parses an LLM response searching for API calls. It looks for the <API> pattern defined in the plugins.prompt and extracts the plugin name, operation ID, and parameters.
Call API
The call_api() function calls an operation in an active plugin. It takes the plugin name, operation ID, and parameters extracted by parse_llm_response() and makes a request to the plugin API.
Plugin Authentication: Plugins with Oauth, user or service level authentication pass api_key(string) as parameter. For oauth, use the access_token as the api_key parameter. For more detail about oauth authentication please see oauth_example/run_plugin_with_oauth.py and oauth_example/oauth_server.py files.
Apply Plugins
The @plugins.apply_plugins decorator can be used to easily apply active plugins to an LLM function.
This method is suboptimal for GPT chat models because it doesn't make use of the different available roles on the chat api (system, user, or assistant roles). But it may be useful for other LLM providers or open-source models.

Import the Plugins class and decorator:

from plugnplai import Plugins, plugins.apply_plugins


Define your LLM function, that necessarily takes a string (the user input) as the first argument and returns a string (the response):

@plugins.apply_plugins
def call_llm(user_input):
...
return response


The decorator will handle the following:


Prepending the prompt (with plugin descriptions) to the user input
Checking the LLM response for API calls (the ... pattern)
Calling the specified plugins
Summarizing the API calls in the LLM response
Calling the LLM function again with the summary to get a final response


If no API calls are detected, the original LLM response is returned.

To more details on the implementation of these steps, see example "Step by Step":
Plugins Retrieval
PlugnPlai Retrieval API - https://www.plugnplai.com/_functions/retrieve?text={user_message_here} :
Build our own Plugins Vector Database:
from plugnplai import PluginRetriever

# Initialize the plugins retriever vector database and index the plugins descriptions.
# Loading the plugins from plugnplai.com directory
plugin_retriever = PluginRetriever.from_directory()

# Retrieve the names of the plugins given a user's message
plugin_retriever.retrieve_names("what shirts can i buy?")
