How to: LangChain Tokenbooks - crypto and fiat accounting and payments preview_transaction_classification
Add Tokenbooks - crypto and fiat accounting and payments 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({
"tokenbooks": {
"transport": "streamable_http",
"url": "https://api.tokenbooks.io/mcp",
}
})
tools = await client.get_tools()
-
02
Save the file and restart LangChain.
-
03
Ask for something preview_transaction_classification does. LangChain lists the server's tools on connect and calls preview_transaction_classification itself — you do not invoke it by name.
-
04
If nothing happens, check the server is running and that Tokenbooks - crypto and fiat accounting and payments'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.
