Serac is a terminal-native AI development agent purpose-built for ServiceNow. It brings 429 ServiceNow MCP tools, 55 bundled domain skills (including Blast Radius impact analysis), and 20+ AI providers into your own terminal — your editor, your keys (BYOK), and any instance you connect to. It's built for ServiceNow developers and the consultants who work across many client instances. Serac extends the open-source opencode agent with a deep ServiceNow domain layer.
