LangChain is a composable framework to build LLM applications. It can be combined with LangGraph which is a stateful, orchestration framework that brings added control to agent workflows. You can deploy your LangChain or LangGraph projects to Blaxel with minimal code editing (and zero configuration), enabling you to use Serverless Deployments, Agentic Observability, Policies, and more.
Get started with LangChain on Blaxel
To get started with LangChain/LangGraph on Blaxel:
- if you already have a LangChain or LangGraph agent, adapt your code with Blaxel SDK commands to connect to MCP servers, LLMs and other agents.
- or initialize an example project in LangChain by using the following Blaxel CLI command and selecting the LangChain hello world:
Deploy it by running:
Develop a LangChain agent using Blaxel features
While building your agent in LangChain, use Blaxel SDK to connect to resources already hosted on Blaxel:
Connect to MCP servers
Connect to MCP servers using the Blaxel SDK to access pre-built or custom tool servers hosted on Blaxel. This eliminates the need to manage server connections yourself, with credentials stored securely on the platform.
Run the following command to retrieve tools in LangChain format:
from blaxel.langgraph import bl_tools
await bl_tools(['mcp-server-name'])
Connect to LLMs
Connect to LLMs hosted on Blaxel using the SDK to avoid managing model API connections yourself. All credentials remain securely stored on the platform.
from blaxel.langgraph import bl_model
model = await bl_model("model-api-name")
Connect to other agents
Connect to other agents hosted on Blaxel from your code by using the Blaxel SDK. This allows for multi-agent chaining without managing connections yourself. This command is independent of the framework used to build the agent.
from blaxel.core.agents import bl_agent
response = await bl_agent("agent-name").run(input);
Host your agent on Blaxel
You can deploy your agent on Blaxel, enabling you to use Serverless Deployments, Agentic Observability, Policies, and more. This command is independent of the framework used to build the agent.
Either run the following CLI command from the root of your agent repository.
Or connect a GitHub repository to Blaxel for automatic deployments every time you push on main.
