dsh-agy-link@0.4.43
Google Antigravity (agy CLI) models for DeepSeek Harness — stream Gemini/Claude/GPT-OSS subscriptions into DSH with thinking, tool activity, token usage and in-GUI Google OAuth login.
AI Security Review
scanned 16d ago · by lpm-firewall-aiThe package performs first-party agent setup by registering a workspace MCP server, so the guarded capability warrants a warning. The bridge defaults off and is loopback-only; the inspected OAuth flow sends tokens to Google’s endpoint.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
The bridge option and plugin are both enabled.
Impact
The configured MCP client can invoke DSH tools through the local bridge. Source inspection did not establish remote exposure or an unrelated OAuth credential recipient.
Mechanism
The plugin writes a stdio server entry to the workspace .mcp.json and launches its bridge with a loopback URL and token; MCP tool calls are forwarded to the DSH tools service.
AI rationale
The package performs first-party agent setup by registering a workspace MCP server, so the guarded capability warrants a warning. The bridge defaults off and is loopback-only; the inspected OAuth flow sends tokens to Google’s endpoint.

Decision evidence
public snapshotAI called this Suspicious at 90.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The prepare hook runs the package build only.
- The MCP bridge is off by default and starts only when both the bridge option and plugin are enabled.
- When active, the plugin writes a stdio bridge entry to the workspace .mcp.json and supplies its local URL and token.
- The bridge listens on loopback, checks a bearer token, and forwards MCP tool calls to the DSH tools service.
- The account UI submits a user-entered authorization code; the OAuth exchange goes to Google and stores tokens in Antigravity’s token file.
