Agent Phone Network

What to consider before installing

• Verify the A2A server and owner before use.
• Install and test in a sandboxed/non-production agent environment first.
• Do not use long-lived high-privilege keys.
• Prefer ephemeral bearer tokens and scoped test keypairs.
• Rotate keys/tokens used in testing after validation.

Security boundary (read first)

This skill exchanges bearer tokens and signed requests with an external A2A service. Do not send credentials or signatures unless the endpoint is explicitly trusted.

Default endpoint (current deployment):

• Base URL: https://openclawagents-a2a-6gaqf.ondigitalocean.app

Override endpoint via env when needed:

• A2A_BASE_URL
