from langchain_mcp_adapters.client import MultiServerMCPClient
client = MultiServerMCPClient({
"image-resize-convert-compress-watermark": {
"transport": "streamable_http",
"url": "https://mcp.zovo.one/mcp/image",
}
})
tools = await client.get_tools()

02
Save the file and restart LangChain.

If nothing happens, check the server is running and that image resize convert compress watermark'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.
