LangChain Mail Security Tools email_fix_plan

How to: LangChain Mail Security Tools email_fix_plan

client:LangChain transport:streamable-http tool:email_fix_plan

Add Mail Security Tools 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({
        "email-security": {
            "transport": "streamable_http",
            "url": "https://api.mailsecuritytools.com/mcp",
        }
})

tools = await client.get_tools()
  1. 02

    Save the file and restart LangChain.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that Mail Security Tools'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 14 October 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.
