langchain-mnki
LangChain / LangGraph tools guarded by mnki (Agent Trust): every tool call is verified against the agent's delegated authority, with an evidence list, before it runs.
pip install langchain-mnki
import os
from mnki import AgentTrustClient, Guard
from langchain_mnki import guard_tools
from langgraph.prebuilt import create_react_agent
g = Guard(AgentTrustClient("https://mnki.com", api_key=os.environ["MNKI_API_KEY"]), agent="invoice-agent")
graph = create_react_agent(model, guard_tools(g, [refund, lookup]))
- Tools stay
BaseToolinstances (aGuardedToolsubclass), soToolNode,bind_toolsand isinstance checks work. - A refused call returns
{"error": "denied", "reasons": [...], "evidence": [...]}to the model;on_refused="throw"raises. - Calls that policy escalates wait for a human approval (phone app) and continue when approved.
- No account needed to try it:
Guard(world=demo_world(), agent="invoice-agent")runs the same verifier offline.
Pinned versions and the support level are in the compatibility matrix; every
integration path is on one page at https://mnki.com/docs/integrations. The implementation is
mnki.adapters.langchain in the mnki package; this distribution is its
LangChain-facing name. Apache-2.0.
