Gemini × Hail

Gemini CLI and Code Assist both speak MCP. Hail registers as a tool group that Gemini surfaces in any agentic workflow.

Three steps. That's the bar.

~120 SECONDS · COFFEE OPTIONAL
01

Grab an API key

Sign in to the Hail console and create a project key. Keep it scoped to the project — you can rotate or kill it any time without touching the rest of your stack.

console.hail.so → Keys → New
02

Drop Hail into your config

Add the Hail MCP server using the snippet below. Paste it where this client expects MCP servers — the path varies, the shape doesn't.

Gemini CLI → /mcp add hail

SHELL · Terminal

gemini mcp add hail \
  --url https://mcp.hail.so/v1 \
  --header "Authorization: Bearer hl_live_••••"
03

Try it once. It works or it doesn't.

Reload the client. The Hail tools should surface in the agent's toolset. Send the prompt below — if a call is placed, an SMS lands, or an email shows up in the inbox view, you're done.

gemini "use hail to call dr. allen's office and reschedule"
■ NOTES & GOTCHAS

  • Streaming transcripts surface as tool-result events.

Hail your first call — from this client.

Self-host on your own carrier or claim a managed number. Either way, your agent picks up the phone in ~120 seconds.
