[Bug]: For A2A Agent test not working

[sunvk]

🐞 Bug Summary

Created a sample A2A Agent. Will provide the code below.

1. A2A agent is exposed as an api endpoint and takes a user query. There is no way to test this A2A Agent from the UI, as no field to pass the user input.

2. Tools from the A2A Agent is not getting listed under the Global Tools Tab.

Sample A2A Agent code:

`
import random

def calculator(expression: str) -> str:
"""Evaluate a math expression safely."""

try:

    result = eval(expression, {"__builtins__": {}})

    return str(result)

except Exception as e:

    return f"Error: {e}"

def weather(city: str) -> str:

"""Mock weather lookup tool."""

conditions = ["sunny", "rainy", "cloudy", "stormy"]

temp = random.randint(10, 35)

return f"The weather in {city} is {random.choice(conditions)}, {temp}°C"

`

from a2a_agent.tools import calculator, weather class SimpleAgent: def __init__(self, name="Agent"): self.name = name self.tools = { "calculator": calculator, "weather": weather, } def run(self, query: str) -> str: # Very basic routing if "calc:" in query: expr = query.replace("calc:", "").strip() return self.tools["calculator"](expr) elif "weather:" in query: city = query.replace("weather:", "").strip() return self.tools["weather"](city) else: return f"{self.name} does not understand the query."

from a2a_agent.agent import SimpleAgent def main(): agent = SimpleAgent("A2A-Agent") print("A2A Agent started. Try queries like:") print(" calc: 5*10+2") print(" weather: Dallas") while True: query = input("\n> ") if query.lower() in ["exit", "quit"]: break print(agent.run(query)) if __name__ == "__main__": main()

`from fastapi import FastAPI

from pydantic import BaseModel

from a2a_agent.agent import SimpleAgent

app = FastAPI(title="A2A Agent API")

agent = SimpleAgent("A2A-Agent")

class Query(BaseModel):

query: str

@app.post("/run")

def run_agent(req: Query):

response = agent.run(req.query)

return {"response": response}

`

uv run uvicorn a2a_agent.api:app --host 0.0.0.0 --port 8000

`curl -X POST "http://localhost:8000/run" \

-H "Content-Type: application/json" \

-d '{"query": "calc: 7*8"}'

curl -X POST "http://localhost:8000/run" \

-H "Content-Type: application/json" \

-d '{"query": "weather: Dallas"}'
`

`A2A Agent started. Try queries like:

calc: 5*10+2

weather: Dallas

calc: 7*9

63

weather: Houston

The weather in Houston is sunny, 28°C
