Frenchie in Google Antigravity
Invoke MCP servers by name, not by skill name.
Install
From your project root:
npx @lab94/frenchie install --agent antigravity --global --api-key fr_your_key_hereNeed help picking an agent? See the invocation matrix.
Invoke
Primary pattern:
/frenchie TOR.pdfAntigravity invokes MCP servers directly by name, not skills or commands. That means /ocr and @frenchie are ignored — only /<server-name> reaches the tool layer. Since our server is registered as frenchie, that means /frenchie TOR.pdf.
Example
You:
/frenchie TOR.pdfAgent:
Antigravity routes to ocr_to_markdown. The file is processed, .frenchie/TOR/result.md lands in your project.
Known gotchas
macOS GUI PATH gap
When Antigravity is launched from Dock / Spotlight (not from a terminal), it inherits a sterile launchd environment with no shell PATH. Layer A fails with exec: npx: executable file not found in $PATH; layer B fails with env: node: No such file or directory. Frenchie 0.3.0 fixes both by writing the absolute path to npx plus a scoped PATH into the MCP config's env block. Re-run install to pick up the fix.
