A2A Inspector

Connect, discover, and test Agent-to-Agent (A2A) protocol agents

Agent requests can use your browser or the server proxy

Why: Discovery, messages and streams contact the configured agent. Proxy mode and CORS fallback use this deployment's server routes.

Data sent:

Target URL, configured headers and credentials, and the request payload
Agent discovery URLs, message parts, task identifiers and stream requests

Data handling: Direct mode sends requests from your browser to the target. Proxy mode sends the configured request through this deployment; the target also receives it. Review credentials and payloads before sending.
