btp-guard • BTP v2.2 Universal Agent Trust Guard
Cryptographic Governance for LangGraph, AutoGen, CrewAI & LlamaIndex
btp-guard is the official Python SDK for the Bartholomew Trust Protocol (BTP v2.2). It provides 100% offline, zero-network mathematical verification of autonomous agent trajectories, tool executions, and cross-framework delegations using RFC 8785 JSON Canonicalization (JCS) and FIPS 186-5 Ed25519 signatures.
Installation
pip install btp-guard
Quickstart: 1-Line Tool Guard (LangGraph / LangChain)
from btp_guard import BTPGuard
# 1. Initialize guard with your organization's recognized root authorities
guard = BTPGuard(
trusted_authorities=["<64-hex-char-ed25519-public-key>"],
agent_id="Agent-Production-Cluster"
)
# 2. Decorate critical tools
@guard.wrap_tool
def execute_sql_patch(sql_query: str):
# Automatically blocked if unauthenticated or payload tampered
return db.execute(sql_query)
Quickstart: Microsoft AutoGen Interceptor
from btp_guard import BTPGuard
guard = BTPGuard(trusted_authorities=[ROOT_KEY])
# Drops or alerts on unattested high-privilege tool requests in transit
safe_message = guard.intercept_autogen_message(inbound_packet)
Quickstart: Standalone Offline Verification (Zero-SDK)
from btp_guard import verify_btp_receipt
ok, msg = verify_btp_receipt(
receipt_json_str=inbound_packet,
candidate_payload={"file": "worker.py", "patch": "fix()"},
trusted_root_pubkeys=[ROOT_KEY],
expected_recipient_context="Agent-Production-Cluster"
)
if not ok:
raise PermissionError(f"Attestation rejected: {msg}")
