LangChain Perigee perigee_object

How to: LangChain Perigee perigee_object

client:LangChain transport:streamable-http tool:perigee_object

Add Perigee 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({
        "perigee": {
            "transport": "streamable_http",
            "url": "https://perigee-mcp.perigeeinfo.workers.dev/mcp",
        }
})

tools = await client.get_tools()
  1. 02

    Save the file and restart LangChain.

  2. 03

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

  3. 04

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

Perigee will not start until these are set, so perigee_object never becomes available.

  • PERIGEE_SITE
  • PERIGEE_MCP_CACHE

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 11 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.
