# Langchain - Robocorp Action Server
|
|
|
|
This template enables using [Robocorp Action Server](https://github.com/robocorp/robocorp) served actions as tools for an Agent.
|
|
|
|
## Usage
|
|
|
|
To use this package, you should first have the LangChain CLI installed:
|
|
|
|
```shell
|
|
pip install -U langchain-cli
|
|
```
|
|
|
|
To create a new LangChain project and install this as the only package, you can do:
|
|
|
|
```shell
|
|
langchain app new my-app --package robocorp-action-server
|
|
```
|
|
|
|
If you want to add this to an existing project, you can just run:
|
|
|
|
```shell
|
|
langchain app add robocorp-action-server
|
|
```
|
|
|
|
And add the following code to your `server.py` file:
|
|
|
|
```python
|
|
from robocorp_action_server import agent_executor as action_server_chain
|
|
|
|
add_routes(app, action_server_chain, path="/robocorp-action-server")
|
|
```
|
|
|
|
### Running the Action Server
|
|
|
|
To run the Action Server, you need to have the Robocorp Action Server installed
|
|
|
|
```bash
|
|
pip install -U robocorp-action-server
|
|
```
|
|
|
|
Then you can run the Action Server with:
|
|
|
|
```bash
|
|
action-server new
|
|
cd ./your-project-name
|
|
action-server start
|
|
```
|
|
|
|
### Configure LangSmith (Optional)
|
|
|
|
LangSmith will help us trace, monitor and debug LangChain applications.
|
|
LangSmith is currently in private beta, you can sign up [here](https://smith.langchain.com/).
|
|
If you don't have access, you can skip this section
|
|
|
|
```shell
|
|
export LANGCHAIN_TRACING_V2=true
|
|
export LANGCHAIN_API_KEY=<your-api-key>
|
|
export LANGCHAIN_PROJECT=<your-project> # if not specified, defaults to "default"
|
|
```
|
|
|
|
### Start LangServe instance
|
|
|
|
If you are inside this directory, then you can spin up a LangServe instance directly by:
|
|
|
|
```shell
|
|
langchain serve
|
|
```
|
|
|
|
This will start the FastAPI app with a server is running locally at

|
|
|
We can access the template from code with:
|
|
|
|
```python
|
|

|
|
|
runnable = RemoteRunnable("http://localhost:8000/robocorp-action-server")
