LangChain Sec 13f entity_profile

How to: LangChain Sec 13f entity_profile

client:LangChain transport:streamable-http tool:entity_profile

Add Sec 13f 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({
        "sec-13f": {
            "transport": "streamable_http",
            "url": "https://gateway.pipeworx.io/sec-13f/mcp",
        }
})

tools = await client.get_tools()
  1. 02

    Save the file and restart LangChain.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that Sec 13f'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

Sec 13f will not start until these are set, so entity_profile never becomes available.

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 14 November 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.
