Connect Antigravity

Add PMM Sherpa to Google's Antigravity IDE.

Antigravity is Google's agentic IDE. It supports Streamable HTTP MCP servers through a JSON config.

Steps#

  1. Open the MCP store in Antigravity → Manage MCP Servers → View raw config.
  2. This opens mcp_config.json:
    • macOS / Linux: ~/.gemini/antigravity/mcp_config.json
    • Windows: C:\Users\<you>\.gemini\antigravity\mcp_config.json
  3. Add PMM Sherpa under mcpServers:
{
  "mcpServers": {
    "pmm-sherpa": {
      "httpUrl": "https://pmmsherpa.com/api/mcp"
    }
  }
}
  1. Save. Antigravity hot-reloads and triggers OAuth on the first tool call.

Auth#

Browser OAuth on first use. Tokens persist across sessions.

Limitations#

Per-workspace MCP config is still being rolled out. For now, this config is global across all Antigravity workspaces. Disabling per-workspace is not yet supported, so consider that when sharing machines.

Troubleshooting#

  • Tools missing after save: confirm the JSON is valid (httpUrl, not url). Quit and relaunch Antigravity.
  • OAuth window blocked: allow pop-ups for pmmsherpa.com, then re-trigger any tool call.
  • Want staging: use https://staging.pmmsherpa.com/api/mcp and a staging account.
