toolbroker-crewai

CrewAI adapter for ToolBroker.

pip install toolbroker-crewai

from crewai import Agent, Crew, Task
from toolbroker import ToolBroker

broker = ToolBroker()
broker.add_functions([search_orders, issue_refund, check_inventory])
broker.index()

tools, selection = broker.select_for("crewai", "customer wants a refund", k=3)
agent = Agent(role="Support", goal="Help the customer", backstory="...", tools=tools)

CrewAI pulls a large dependency tree. That is precisely why this is a separate package — nothing reaches the ToolBroker core, and installing it affects only you.

Schemas

CrewAI wants args_schema as a pydantic model class, not a JSON Schema dict, so this adapter builds one per tool with toolbroker.schema.model_from_schema. Awkward parameter names are handled: order-id becomes order_id with an alias, and a parameter called schema or class gets mangled and aliased rather than shadowing a pydantic or Python name.

Anything the converter cannot map degrades to a permissive field. A tool the model can still call with loose typing beats one that disappeared because its schema used a construct nobody anticipated.

Remote tools

Tools with no local callable need an invoker, or the adapter refuses rather than emitting one that fails when the agent calls it:

CrewAIAdapter(invoker=lambda tool, kwargs: my_client.call(tool, kwargs))
