bolyra-crewai 0.1.0

CrewAI tools for Bolyra mutual ZKP authentication and SD-JWT delegation

Bolyra CrewAI Integration

Status: Alpha (0.1.0) -- Mutual ZKP authentication, scoped delegation, and SD-JWT tools for CrewAI multi-agent workflows.

Install

pip install bolyra-crewai

# For ZKP tools (auth + delegate), also need Node.js bridge:
npm install @bolyra/sdk && npx bolyra setup

Quick Start

from crewai import Agent, Crew, Task
from bolyra_crewai import (
    BolyraAuthTool,
    BolyraDelegateTool,
    BolyraSDJWTTool,
    BolyraGuard,
    BolyraSession,
)

# 1. Create tools
auth = BolyraAuthTool(permissions=["read_data", "write_data"])
delegate = BolyraDelegateTool(agent_permissions=["read_data", "write_data"])
sd_jwt = BolyraSDJWTTool()

# 2. Create session + guard
session = BolyraSession(auth_tool=auth, delegate_tool=delegate, sd_jwt_tool=sd_jwt)
guard = BolyraGuard(session=session, on_failure="raise")

# 3. Wrap tools with pre-execution auth enforcement
analyst_tools = guard.guard_tools([auth, sd_jwt])
delegator_tools = guard.guard_tools([delegate])

# 4. Build agents
analyst = Agent(
    role="Authenticated Data Analyst",
    goal="Analyze data only after mutual ZKP authentication",
    tools=analyst_tools,
)

delegator = Agent(
    role="Delegation Manager",
    goal="Delegate scoped permissions to sub-agents",
    tools=delegator_tools,
)

# 5. Build crew
crew = Crew(
    agents=[analyst, delegator],
    tasks=[
        Task(
            description="Authenticate and analyze the dataset",
            expected_output="Analysis report",
            agent=analyst,
        ),
    ],
)

Tools

BolyraAuthTool

Mutual ZKP handshake authentication. Returns a JSON string with session nonce, scope commitment, and nullifiers.

auth = BolyraAuthTool(
    permissions=["read_data", "write_data"],
    agent_model_hash="gpt-4o",        # optional
    operator_key="0xdeadbeef...",       # optional (dev mode if omitted)
    human_secret=12345,                # optional (dev mode if omitted)
    expiry_seconds=86400,              # credential validity
)

BolyraDelegateTool

Scoped permission delegation with cryptographic scope narrowing. Permissions are passed as a comma-separated string.

delegate = BolyraDelegateTool(
    agent_permissions=["read_data", "write_data", "financial_small"],
)

# CrewAI agent calls with:
# permissions="read_data, write_data"  (comma-separated string)

BolyraSDJWTTool

Lightweight SD-JWT delegation (pure Python, no Node.js). Raw receipts are vaulted internally -- only JTI references appear in tool output.

tool = BolyraSDJWTTool(dev_mode=True)  # auto-generates Ed25519 keys

# Production mode:
from bolyra.sd_jwt import generate_ed25519_keypair
issuer_priv, _ = generate_ed25519_keypair()
tool = BolyraSDJWTTool(
    issuer_private_key=issuer_priv,
    issuer_kid="my-key-1",
    dev_mode=False,
)

BolyraGuard

Two enforcement modes:

Pre-execution (recommended): wraps tools so auth is checked before execution:

guard = BolyraGuard(
    session=session,
    on_failure="raise",      # "raise" | "warn" | "skip"
    session_ttl_seconds=3600, # optional session expiry
)

# Wrap tools for pre-execution enforcement
tools = guard.guard_tools([auth, sd_jwt, delegate])

analyst = Agent(role="Analyst", tools=tools, ...)
crew = Crew(agents=[analyst], tasks=[...])

Post-execution audit: hooks into CrewAI's step callback (fires after each step):

crew = Crew(..., step_callback=guard.step_callback)

BolyraSession

Stateful session that chains handshake -> delegate -> SD-JWT flows. Thread-safe.

session = BolyraSession(auth_tool=auth, delegate_tool=delegate, sd_jwt_tool=sd_jwt)

# Authenticate
result = session.authenticate(scope="my-app")

# Delegate (session_nonce + scope_commitment auto-injected)
result = session.delegate(delegatee_id="0xabc", permissions="read_data")

# Authorize via SD-JWT
result = session.authorize(action="read", audience="api.example.com")

# Reset
session.reset()

Security

• Receipt vaulting: Raw SD-JWT bearer credentials never appear in tool output (which flows through the LLM context). Only JTI references are returned.
• Dev mode guard: Set BOLYRA_ENV=production to block dev-mode auto-generated identities.
• Scope narrowing: Delegation enforces one-way narrowing at both the SDK and circuit level.
• Nonce binding: Every handshake commits to a fresh session nonce. Replay requires rebinding.
• Canonical nonce format: (unix_seconds << 64) | os.urandom(8) for dev-mode SD-JWT nonces.

Non-Monorepo Setup

If you installed bolyra from PyPI (not from the monorepo checkout), the Python SDK needs to know where the Node.js @bolyra/sdk package lives:

export BOLYRA_NODE_SDK_PATH=/path/to/node_modules/@bolyra/sdk

Inside the monorepo, the SDK auto-discovers ../sdk and no configuration is needed.
