LangChain Time convert_time
How to: LangChain Time convert_time
client:LangChain
transport:stdio
tool:convert_time
Add Time to LangChain
-
01
Open pip install langchain-mcp-adapters and merge this in. Keep any servers already there.
from langchain_mcp_adapters.client import MultiServerMCPClient
client = MultiServerMCPClient({
"time": {
"transport": "stdio",
"command": "uvx",
"args": ["mcp-server-time"],
}
})
tools = await client.get_tools()
-
02
Save the file and restart LangChain.
-
03
Ask for something convert_time does. LangChain lists the server's tools on connect and calls convert_time itself — you do not invoke it by name.
-
04
If nothing happens, check the server is running and that Time's identifier in your config matches the one above exactly.
get_tools() returns the server's tools as LangChain tools, ready for an agent. LangChain docs
Same tool, other clients
Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
