Agents can use two public FirstSales surfaces:
  • Developer API for any tool that can send HTTPS requests.
  • firstsales CLI for local shells, coding agents, CI, and scripts.
Agents should prefer the CLI when shell access exists because it centralizes auth, JSON output, idempotency headers, and destructive confirmation behavior. When shell access does not exist, use the API examples directly.

MCP

The MCP integration guide is available at FirstSales MCP server. It documents the Product MCP resource, the modern 2026-07-28 and legacy 2025-11-25 contracts, and the OAuth grant model. The synchronized release manifest has release_ready: true. The current released tool catalog is read-only; no approval-backed Product MCP action is released. The MCP guide renders its complete tool list from the machine-owned parity artifact.
