Robocorp is the easiest way to extend the capabilities of AI agents, assistants and copilots with custom actions, written in Python. Create and deploy tools, skills, loaders and plugins that securely connect any AI Assistant platform to your data and applications.

Robocorp Action Server makes your Python scripts compatible with ChatGPT and LangChain by automatically creating and exposing an API based on function declaration, type hints and docstrings. Just add @action and start!

Looking for a replacement to RPA? Head over to our Enterprise Python Automation site for more.

There are two main ways using the Action Server: use with our Robocorp Code extension for VS Code, or DIY from the command line. This section gets you going!

brew update
brew install robocorp/tools/action-server

# Download Robocorp Action Server
curl -o action-server.exe https://downloads.robocorp.com/action-server/releases/latest/windows64/action-server.exe

# Download Robocorp Action Server
curl -o action-server https://downloads.robocorp.com/action-server/releases/latest/linux64/action-server
chmod a+x action-server

# Add to PATH or move to a folder that is in PATH
sudo mv action-server /usr/local/bin/

Bootstrap a new project from a template. You’ll be prompted for the name of the project:

action-server new

Navigate to the freshly created project folder and start the server:

cd my-project
action-server start --expose

👉 You should now have an Action Server running locally at: http://localhost:8080, to open the web UI.

👉 Using the --expose -flag, you also get a public internet-facing URL (something like twently-cuddly-dinosaurs.robocorp.link) and an API key. These are the details that you need to configure your AI Agent.

Head over to Action Server docs for more.

1️⃣ package.yaml file that describes the set of Actions your are working on, and defines up your Python environment and dependencies:

name: Package name
description: Action package description
version: 0.0.1
documentation: https://github.com/...

dependencies:
  conda-forge:
  - python=3.10.12
  - pip=23.2.1
  - robocorp-truststore=0.8.0
  pypi:
  - robocorp=1.6.1
  - robocorp-actions=0.0.7
  - pytz=2023.3

2️⃣ @action decorator that determines the action entry point and Type hints and docstring to let AI agents know what the Action does in natural language.

@action
def greeting(name: str) -> str:
    """
    Greets the user

    Args:
        name (str): The user name

    Returns:
        str: Final user greeting
    """

Once you have started the Action Server with --expose flag, you’ll get a URL available to the public, along with the authentication token. The relevant part of the output from the terminal looks like this, of course with your own details:

...
Uvicorn running on http://localhost:8080 (Press CTRL+C to quit)
🌍 URL: https://seventy-six-helpless-dragonflies.robocorp.link
🔑 Add following header api authorization header to run actions: { "Authorization": "Bearer xxx_xxx" }

Adding the Action Server-hosted AI Action to your custom GPT is super simple: basically just navigate to “Actions” section of the GPT configuration, add the link to import the actions, and Add Authentication with Authentication method set to “API key” and Auth Type to “Bearer”.

TIP:
Use the @action(is_consequential=False) flag to avoid the user needing to accept the action execution separately each time on your GPT.

Robocorp Action Server has everything needed to connect it to your Langchain AI app project. The easiest way is to start with the template provided in the Langchain project. Here’s how to do it:

# Install LangChain cli tool if not already there
pip install langchain-cli

# Create a new LangChain app using Action Server template
langchain app new my-awesome-app --package robocorp-action-server

Then define the route inside the created ./my-awesome-app/app/server.py file:

from langserve import add_routes
+ from robocorp_action_server import agent_executor as action_server_chain

# Edit this to add the chain you want to add
- add_routes(app, NotImplemented)
+ add_routes(app, action_server_chain, path="/robocorp-action-server")

After the setup make sure you have:

• An environment variable OPENAI_API_KEY with your OpenAI API key set
• You have a running Action Server at http://localhost:8080

Finally, inside the project directory ./my-awesome-app spin up a LangServe instance directly by:

langchain serve

After running the steps above, you’ll have a Playground available at http://127.0.0.1:8000/robocorp-action-server/playground/ where you can test your Actions with an AI agent.

Want to build your own thing? Adding your Robocorp AI Actions to a Langchain project is as easy as the code below. Just remember to change the URL of the Action Server if you are not running both the Action Server and Langchain app on the same machine.

from langchain_robocorp import ActionServerToolkit

# Initialize Action Server Toolkit
toolkit = ActionServerToolkit(url="http://localhost:8080")
tools = toolkit.get_tools()

Robocorp stack is hands down the easiest way to give AI agents more capabilities. It’s an end-to-end stack supporting every type of connection between AI and your apps and data. You are in control where to run the code and everything is built for easiness, security, and scalability.

• 🔐 Decouple AI and Actions that touches your data/apps - Clarity and security with segregation of duties between your AI agent and code that touches your data and apps. Build @action and use from multiple AI frameworks.
• 🏎️ Develop Actions faster with robocorp automation libraries - Robocorp libraries and the Python ecosystem lets you act on anything - from data to API to Browser to Desktops.
• 🕵️ Observability out of the box - Log and trace every @action run automatically without a single print statement. Pro tip: connect LangSmith traces with Action logs!
• 🤯 No-pain Python environment management - Don't do this. Robocorp manages a full Python environment for your actions with ease.
• 🚀 Deploy with zero config and infra - One step deployment, and you'll be connecting your @action to AI apps like Langchain and OpenAI GPTs in seconds.

Check out these example projects for inspiration.

• 🐣 Simplest possible AI Action
• 🤡 Get a random joke or jokes per theme. Showcases how easy it is to work with APIs.
• 🕸️ Open a local Playwright browser and make some Google searches.
• 🖥️ Securely fetch contents of .txt and .pdf files from your local machine's folder in real time.
