3-minute integration. Copy the config for your framework, restart, start calling tools. The public tools work without an API key; the live list is /mcp/tools.json.
Try /do now, no API key needed
# JSON-RPC over Streamable HTTP (legacy SSE deprecated); tools/list needs no key and no initialize

Multi-agent orchestration framework. Python.
Add to: any python file
from crewai_tools import MCPServerAdapter
params = {"url": "https://astranl.com/mcp/streamable", "transport": "streamable-http"}
with MCPServerAdapter(params) as astranl_tools:
# Use in any Agent:
agent = Agent(
role="Coordinator",
tools=astranl_tools,
# ... your other config
)AstraNL tools become callable as crew tools. Each tool call hits /mcp/streamable (legacy /mcp/sse is deprecated).
LLM application framework. Python.
Add to: any python file
from langchain_mcp_adapters.client import MultiServerMCPClient
from langchain_mcp_adapters.tools import load_mcp_tools
client = MultiServerMCPClient({
"astranl": {
"url": "https://astranl.com/mcp/streamable",
"transport": "streamable_http",
}
})
