How to: LangChain npm Release Tracker — new Node.js packages & JavaScript dependency updates (npmwatch) data_session_release_with_proof
Add npm Release Tracker — new Node.js packages & JavaScript dependency updates (npmwatch) to LangChain
-
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({
"data-npm-release-node-package-javascript-dependency": {
"transport": "streamable_http",
"url": "https://a2awire.com/mcp/data/npmwatch-new-npm-package-releases-javascript-dependency-updates-9aad2b/http",
}
})
tools = await client.get_tools()
-
02
Save the file and restart LangChain.
-
03
Ask for something data_session_release_with_proof does. LangChain lists the server's tools on connect and calls data_session_release_with_proof itself — you do not invoke it by name.
-
04
If nothing happens, check the server is running and that npm Release Tracker — new Node.js packages & JavaScript dependency updates (npmwatch)'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 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.
