LangChain pdfedit mcp pdf_edit

How to: LangChain pdfedit mcp pdf_edit

client:LangChain transport:streamable-http tool:pdf_edit

Add pdfedit mcp 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({
        "pdfedit-mcp": {
            "transport": "streamable_http",
            "url": "https://pdfedit-mcp-remote.niubai-pdfedit-remote-worker.workers.dev/mcp",
        }
})

tools = await client.get_tools()
  1. 02

    Save the file and restart LangChain.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that pdfedit mcp'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

Set these first

pdfedit mcp will not start until these are set, so pdf_edit never becomes available.

  • PDFEDIT_BASE_URL

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 16 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.
