LangChain Nostr Signer get_grynvault_account_dashboard

How to: LangChain Nostr Signer get_grynvault_account_dashboard

client:LangChain transport:streamable-http tool:get_grynvault_account_dashboard

Add Nostr Signer 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({
        "nostr-signer": {
            "transport": "streamable_http",
            "url": "https://signer.frontiercrown.com/mcp",
        }
})

tools = await client.get_tools()
  1. 02

    Save the file and restart LangChain.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that Nostr Signer'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.
