beam-crewai 0.5.0

CrewAI integration for Beam Protocol

beam-crewai

beam-crewai is a small Python package that connects CrewAI agents to Beam Protocol using the beam-directory SDK.

It provides two high-level primitives:

• BeamTool: a CrewAI-compatible tool for sending natural-language messages to Beam agents
• BeamAgent: a thin wrapper around the Beam Protocol Python SDK for registration, intent sending, and natural-language conversations

Installation

pip install beam-crewai

Quick Start

1) Create a Beam wrapper

from beam_crewai import BeamAgent

beam = BeamAgent.create(
    agent_name="researcher",
    org_name="acme",
    directory_url="https://api.beam.directory",
    default_recipient="[e-mail]",
)

2) Send a Beam intent

result = beam.send_intent_sync(
    intent="query.status",
    params={"detail": "full"},
)

print(result.success)
print(result.payload)

3) Send a natural-language Beam message

reply = beam.talk_sync("What is the latest account summary?")
print(reply["message"])

Using BeamTool with CrewAI

from crewai import Agent
from beam_crewai import BeamAgent, BeamTool

beam = BeamAgent.create(
    agent_name="ops-assistant",
    org_name="acme",
    directory_url="https://api.beam.directory",
    default_recipient="[e-mail]",
)

beam_tool = BeamTool(
    beam_agent=beam,
    description="Send a message to the CRM Beam agent and return the reply.",
)

agent = Agent(
    role="Operations Assistant",
    goal="Fetch information from partner agents over Beam",
    backstory="A CrewAI agent that delegates partner-system questions to Beam agents.",
    tools=[beam_tool],
)

The tool sends a conversation.message request through Beam and returns the remote agent's text response. If the Beam response has no plain-text message, it falls back to serialized structured payload.

API

BeamAgent

• BeamAgent.create(...): creates a new Beam identity and client
• BeamAgent.from_identity_data(...): rebuilds a wrapper from exported Beam identity data
• register(...) / register_sync(...): registers the local Beam agent in the directory
• send_intent(...) / send_intent_sync(...): sends a Beam intent frame
• talk(...) / talk_sync(...): sends a natural-language Beam message

BeamTool

• Accepts message, optional to, optional context, optional language, and timeout_ms
• Uses the wrapper's default_recipient when to is omitted
• Raises an error on Beam delivery failures so CrewAI can surface the tool failure

Development

Run the package tests with:

python -m unittest discover -s tests
