LangChain 日本の給与・社会保険・労働法 check_leave_exemption

How to: LangChain 日本の給与・社会保険・労働法 check_leave_exemption

client:LangChain transport:streamable-http tool:check_leave_exemption

Add 日本の給与・社会保険・労働法 to LangChain

  1. 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({
        "jp-payroll-mcp": {
            "transport": "streamable_http",
            "url": "https://japan-payroll-api.tsumugi.workers.dev/mcp",
        }
})

tools = await client.get_tools()
  1. 02

    Save the file and restart LangChain.

  2. 03

    Ask for something check_leave_exemption does. LangChain lists the server's tools on connect and calls check_leave_exemption itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that 日本の給与・社会保険・労働法'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

This list was read from the server itself, by connecting to it and calling tools/list on 24 September 2026. It is what the server actually exposes, not what its listing claims.

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.
