FeedbackJar + Google Antigravity

~/.gemini/antigravity/mcp_config.json

Google Antigravity uses mcp_config.json with mcpServers and serverUrl for remote HTTP servers. Add FeedbackJar and your agent can read user feedback while building in Antigravity.

How to connect FeedbackJar to Google Antigravity

1

Create an API token

bash 
# Workspace token: fj_live_...
# Set as environment variable (recommended):
export FEEDBACKJAR_API_KEY="fj_live_..."

→ Never hardcode API tokens in mcp_config.json if the file might be committed to git.

2

Open MCP config in Antigravity

bash 
# In Antigravity IDE:
# 1. Click ... in the agent side panel → MCP Servers
# 2. Click Manage MCP Servers → View raw config

# Or edit directly:
# macOS/Linux: ~/.gemini/antigravity/mcp_config.json
# Windows: %UserProfile%\.gemini\antigravity\mcp_config.json
3

Add FeedbackJar to mcp_config.json

json 
{
  "mcpServers": {
    "feedbackjar": {
      "serverUrl": "https://api.feedbackjar.com/mcp",
      "headers": {
        "Authorization": "Bearer ${FEEDBACKJAR_API_KEY}"
      }
    }
  }
}

→ Antigravity uses serverUrl (not url) for remote HTTP servers. Restart Antigravity after saving.

4

Verify in the agent panel

bash 
# After restart, check MCP Servers in the agent panel.
# FeedbackJar should appear with tools like list_posts, get_post, update_status.

# Try: "Show me the top open bugs from FeedbackJar"
