Google Antigravity Python SDK — v0.1.3 Release Notes

This release introduces per-server MCP timeout configurations and improves local connection error handling.

---

🌟 Key Highlights

• Per-Server MCP Timeout: Added configuration support to set custom timeouts for individual MCP servers.
• Terminal Error Propagation: The local connection now propagates terminal trajectory errors from the localharness as structured exceptions in the Python SDK.

📋 Detailed Changes

Configuration & MCP

• Per-Server Timeout: You can now configure the timeout (in seconds) for each MCP server individually via the timeout_seconds parameter on BaseMcpServerConfig (inherited by stdio and HTTP server configs).

Connection & Error Handling

• Terminal Error Propagation: During local connection runs, if the localharness binary exits with a terminal error, the SDK will now raise an AntigravityExecutionError during step collection.
