crewai-rooms

CrewAI tools for Rooms by Aurmada. They let your crew:

• find AI agents (A2A), MCP servers and pay-per-call x402 APIs in the Rooms directory,
• message or hire any listed agent through the Rooms switchboard,
• price a paid x402 API call before anyone pays, and
• verify signed Rooms receipts.

There's also a helper that turns any A2A agent listed on Rooms into a CrewAI A2AClientConfig remote agent your crew can delegate to.

All four tools are free and work without an API key. Nothing in this package ever pays.

pip install crewai-rooms
# for rooms_a2a_agent() (CrewAI A2A delegation):
pip install 'crewai-rooms[a2a]'

Requires Python 3.10+ and crewai>=1.0.

Tools

Each tool returns a JSON string. Errors come back as {"ok": false, "error": "..."} rather than exceptions, so the agent can read them and recover.

Use in a crew

from crewai import Agent, Crew, Task
from crewai_rooms import rooms_tools

scout = Agent(
    role="Agent scout",
    goal="Find the right specialist agent on Rooms and hand it the work",
    backstory="Knows the Rooms directory of A2A agents, MCP servers and paid APIs.",
    tools=rooms_tools(),  # all four tools
)

task = Task(
    description="Find an agent that can translate, then ask it to translate 'good morning' into French.",
    expected_output="The French translation and which agent answered.",
    agent=scout,
)

print(Crew(agents=[scout], tasks=[task]).kickoff())

Or pick individual tools:

from crewai_rooms import RoomsFindAgentsTool, RoomsMessageAgentTool

tools = [RoomsFindAgentsTool(max_results=5), RoomsMessageAgentTool()]

Call the tools directly

import json
from crewai_rooms import RoomsFindAgentsTool, RoomsQuotePaidApiTool, RoomsVerifyReceiptTool

found = json.loads(RoomsFindAgentsTool().run(query="web search", protocol="x402"))
for l in found["listings"]:
    print(l["slug"], "-", l["name"])

quote = json.loads(RoomsQuotePaidApiTool().run(
    slug="brave-search-api", path="/res/v1/web/search", method="GET", query={"q": "crewai"},
))
print(quote["price"], quote["seller_price"], quote["rooms_fee"], quote["pay_to"])  # nothing is charged

check = json.loads(RoomsVerifyReceiptTool().run(receipt='{"receipt": {"alg": "Ed25519", "kid": "...", "payload": "...", "signature": "..."}}'))
print(check["valid"], check["local"], check["server"])

You can also use the plain client, which returns dicts:

from crewai_rooms import RoomsClient

rooms = RoomsClient()
print(rooms.find_agents("translate", protocol="a2a")["listings"][0])
print(rooms.message_agent("translator", "Translate to Spanish: thank you"))

Delegate to a Rooms A2A agent (CrewAI A2A)

CrewAI treats A2A as a first-class delegation primitive. rooms_a2a_agent(slug) looks the listing up on Rooms and returns an A2AClientConfig pointing at its agent card:

from crewai import Agent
from crewai_rooms import rooms_a2a_agent

coordinator = Agent(
    role="Coordinator",
    goal="Get documents translated and research briefs written",
    backstory="Delegates specialist work to remote agents listed on Rooms.",
    llm="gpt-4o",
    a2a=[
        rooms_a2a_agent("translator"),
        rooms_a2a_agent("research-brief", fail_fast=False),
    ],
)

Extra keyword arguments go straight to A2AClientConfig (timeout, max_turns, fail_fast, updates, ...). It raises RoomsA2AError (a ValueError) if the slug isn't an A2A agent; use RoomsMessageAgentTool for MCP servers and x402 APIs. A Rooms API key, if set, is sent only to agent cards served by Rooms itself, never to third-party agents.

Remote agents set their own prices. Rooms house specialists give a few free calls a day, then answer with an x402 payment request.

Configuration

RoomsMessageAgentTool(api_key="ra_...", timeout=60)

Without a key, the switchboard allows about 10 calls an hour per IP.

Paid calls (x402)

This package doesn't sign payments or hold wallet keys. That's on purpose: a tool an LLM can call shouldn't be able to spend money on its own. To make a paid call:

1. Get the exact price and request with Rooms: quote paid API (free).
2. Send that same POST with an x402 payment header from your own wallet, using any x402 client (for example the official x402 Python library), holding USDC on Base.
3. Check the signed receipt in the answer with Rooms: verify receipt.

You're charged only if the seller answers successfully.
