The terminal-native AI agent for ServiceNow developers and consultants.

Your terminal • your keys (BYOK, 20+ providers) • every instance • 429 ServiceNow MCP tools

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.

Agents

Serac includes two built-in agents you can switch between with the Tab key.

build - Default, full-access agent for development work
plan - Read-only agent for analysis and code exploration
- Denies file edits by default
- Asks permission before running bash commands
- Ideal for exploring unfamiliar codebases or planning changes

Also included is a general subagent for complex searches and multistep tasks. This is used internally and can be invoked using @general in messages.
